target package: Run the 2 previous installation commands. host package: Run the installation of the package in the host directory. Displays the first-order reverse dependencies of the package i. e packages that directly depend on it. Recursively displays the reverse dependencies of the package i. e the packages that depend on it, directly or indirectly. Generate a dependency graph of the package, in the context of the current Buildroot configuration.

See this section for more details about dependency graphs. Generate a graph of this package reverse dependencies i. The normal operation of Buildroot is to download a tarball, extract it, configure, compile and install the software component found inside this tarball. Even when a Git or Subversion repository is used as the input for the package source code, Buildroot creates a tarball out of it, and then behaves as it normally does with tarballs.

This behavior is well-suited when Buildroot is used mainly as an integration tool, to build and integrate all the components of an embedded Linux system. However, if one uses Buildroot during the development of certain components of the system, this behavior is not very convenient: one would instead like to make a small change to the source code of one package, and be able to quickly rebuild the system with Buildroot.

Buildroot reads an override file, which allows the user to tell Buildroot the location of the source for certain packages. config file, so local. mk by default lives side-by-side with the. config file, which means:. In this override file, Buildroot expects to find lines of the form:.

Instead, it will directly use the source code available in the specified directory and make clean will not touch this directory. This allows to point Buildroot to your own directories, that can be managed by Git, Subversion, or any other version control system. Source trees for big projects often contain hundreds or thousands of files which are not needed for building, but will slow down the process of copying the sources with rsync.

For example, when working on the webkitgtk package, the following will exclude the tests and in-tree builds from a local WebKit source tree:. By default, Buildroot skips syncing of VCS artifacts e. git and. svn directories. Some packages prefer to have these VCS directories available during build, for example for automatically determining a precise commit reference for version information. To undo this built-in filtering at a cost of a slower speed, add these directories back:.

An important note regarding such project-specific customizations: please carefully consider which changes are indeed project-specific and which changes are also useful to developers outside your project. The Buildroot community highly recommends and encourages the upstreaming of improvements, packages and board support to the official Buildroot project. Of course, it is sometimes not possible or desirable to upstream because the changes are highly specific or proprietary.

This chapter describes how to make such project-specific customizations in Buildroot and how to store them in a way that you can build the same image in a reproducible way, even after running make clean. By following the recommended strategy, you can even use the same Buildroot tree to build multiple distinct projects!

When customizing Buildroot for your project, you will be creating one or more project-specific files that need to be stored somewhere. While most of these files could be placed in any location as their path is to be specified in the Buildroot configuration, the Buildroot developers recommend a specific directory structure which is described in this section. Orthogonal to this directory structure, you can choose where you place this structure itself: either inside the Buildroot tree, or outside of it using a br2-external tree.

Both options are valid, the choice is up to you. It is quite common for a user to have several related projects that partly need the same customizations. Instead of duplicating these customizations for each project, it is recommended to use a layered customization approach, as explained in this section. Almost all of the customization methods available in Buildroot, like post-build scripts and root filesystem overlays, accept a space-separated list of items.

The specified items are always treated in order, from left to right. By creating more than one such item, one for the common customizations and another one for the really project-specific customizations, you can avoid unnecessary duplication. Depending on your projects, you could even introduce more than two layers.

An example directory structure for where a user has two customization layers common and fooboard is:. then first the patches from the common layer would be applied, followed by the patches from the fooboard layer. As already briefly mentioned in Section 9. It can be passed to any Buildroot make invocation. It is automatically saved in the hidden. mk file in the output directory. It can however be changed at any time by passing a new value, and can be removed by passing an empty value.

The path to a br2-external tree can be either absolute or relative. If it is passed as a relative path, it is important to note that it is interpreted relative to the main Buildroot source directory, not to the Buildroot output directory.

Note: If using an br2-external tree from before Buildroot See Section A br2-external tree must contain at least those three files, described in the following chapters:. They are described in the following chapters as well. That file describes the br2-external tree: the name and description for that br2-external tree. The format for this file is line based, with each line starting by a keyword, followed by a colon and one or more spaces, followed by the value assigned to that keyword.

There are two keywords currently recognised:. name , mandatory, defines the name for that br2-external tree. This variable is available both in Kconfig, so you can use it to source your Kconfig files see below and in the Makefile, so that you can use it to include other Makefiles see below or refer to other files like data files from your br2-external tree.

Note: Since it is possible to use multiple br2-external trees at once, this name is used by Buildroot to generate variables for each of those trees. That name is used to identify your br2-external tree, so try to come up with a name that really describes your br2-external tree, in order for it to be relatively unique, so that it does not clash with another name from another br2-external tree, especially if you are planning on somehow sharing your br2-external tree with third parties or using br2-external trees from third parties.

They are also exported in the environment so are available in post-build, post-image and in-fakeroot scripts. Those files which may each be empty can be used to define package recipes i. mk like for packages bundled in Buildroot itself or other custom configuration options or make logic. Buildroot automatically includes the Config. in from each br2-external tree to make it appear in the top-level configuration menu, and includes the external. mk from each br2-external tree with the rest of the makefile logic.

The main usage of this is to store package recipes. The recommended way to do this is to write a Config. in file that looks like:. You can also define custom configuration options in Config. in and custom make logic in external. One can store Buildroot defconfigs in the configs subdirectory of the br2-external tree. They will be visible in the make list-defconfigs output, below an External configs label that contains the name of the br2-external tree they are defined in.

Note: If a defconfig file is present in more than one br2-external tree, then the one from the last br2-external tree is used. It is thus possible to override a defconfig bundled in Buildroot or another br2-external tree.

For some packages, Buildroot provides a choice between two or more implementations of API-compatible such packages. For example, there is a choice to choose either libjpeg ot jpeg-turbo; there is one between openssl or libressl; there is one to select one of the known, pre-configured toolchains…. It is possible for a br2-external to extend those choices, by providing a set of files that define those alternatives:.

For example, you could set the paths to a global patch directory, to a rootfs overlay and to the kernel configuration file as follows e. by running make menuconfig and filling in these options :. Additional Linux kernel extensions see Section Here is an example layout using all features of br2-external the sample content is shown for the file above it, when it is relevant to explain the br2-external tree; this is all entirely made up just for the sake of illustration, of course :.

desc :. options will not appear in the Toolchain menu. in and will thus appear in the External options menu. The Buildroot configuration can be stored using the command make savedefconfig. This strips the Buildroot configuration down by removing configuration options that are at their default value.

The result is stored in a file called defconfig. The configuration files for BusyBox, the Linux kernel, Barebox, U-Boot and uClibc should be stored as well if changed.

For each of these components, a Buildroot configuration option exists to point to an input configuration file, e. To store their configuration, set these configuration options to a path where you want to save the configuration files, and then use the helper targets described below to actually store the configuration. As explained in Section 9. You can create the configuration file by running make linux-menuconfig etc.

The two recommended methods, which can co-exist, are root filesystem overlay s and post build script s. A filesystem overlay is a tree of files that is copied directly over the target filesystem after it has been built.

You can even specify multiple overlays, space-separated. If you specify a relative path, it will be relative to the root of the Buildroot tree. Hidden directories of version control systems, like.

git ,. svn ,. hg , etc. empty and files ending in ~ are excluded from the copy. As shown in Section 9. Post-build scripts are shell scripts called after Buildroot builds all the selected software, but before the rootfs images are assembled. Using post-build scripts, you can remove or modify any file in your target filesystem. You should, however, use this feature with care. Whenever you find that a certain package generates wrong or unneeded files, you should fix that package rather than work around it with some post-build cleanup scripts.

The post-build scripts are run with the main Buildroot tree as current working directory. The path to the target filesystem is passed as the first argument to each script. All the scripts will be passed the exact same set of arguments, it is not possible to pass different sets of arguments to each script.

Below three more methods of customizing the target filesystem are described, but they are not recommended. For temporary modifications, you can modify the target filesystem directly and rebuild the image.

After making your changes, run make to rebuild the target filesystem image. This method allows you to do anything to the target filesystem, but if you need to clean your Buildroot tree using make clean , these changes will be lost.

Such cleaning is necessary in several cases, refer to Section 8. This solution is therefore only useful for quick tests: changes do not survive the make clean command.

Once you have validated your changes, you should make sure that they will persist after a make clean , using a root filesystem overlay or a post-build script. The root filesystem image is created from a target skeleton, on top of which all packages install their files.

The default target skeleton provides the standard Unix filesystem layout and some basic init scripts and configuration files.

However, if the default skeleton is entirely different than what you need, using a custom skeleton may be more suitable. Both options are available in the System configuration menu. This method is not recommended because it duplicates the entire skeleton, which prevents taking advantage of the fixes or improvements brought to the default skeleton in later Buildroot releases.

This is not a complete substitute for actually being root, but is enough for what Buildroot needs. Post-fakeroot scripts are shell scripts that are called at the end of the fakeroot phase, right before the filesystem image generator is called. As such, they are called in the fakeroot context. Post-fakeroot scripts can be useful in case you need to tweak the filesystem to do modifications that are usually only available to the root user.

Note: The difference between post-build scripts above and fakeroot scripts, is that post-build scripts are not called in the fakeroot context. Note: Using fakeroot is not an absolute substitute for actually being root. Sometimes it is needed to set specific permissions or ownership on files or device nodes.

For example, certain files may need to be owned by root. Since the post-build scripts are not run as root, you cannot do such changes from there unless you use an explicit fakeroot from the post-build script.

Instead, Buildroot provides support for so-called permission tables. If you are using a static device table i. not using devtmpfs , mdev , or e udev then you can add device nodes using the same syntax, in so-called device tables.

mk file instead see Section Sometimes it is needed to add specific users in the target system. To cover this requirement, Buildroot provides support for so-called users tables. While post-build scripts Section 9. Post-image scripts can for example be used to automatically extract your root filesystem tarball in a location exported by your NFS server, or to create a special firmware image that bundles your root filesystem and kernel image, or any other custom action required for your project.

Just like post-build scripts, post-image scripts are run with the main Buildroot tree as current working directory. The path to the images output directory is passed as the first argument to each script.

The post-image scripts will be executed as the user that executes Buildroot, which should normally not be the root user. Therefore, any action requiring root permissions in one of these scripts will require special handling usage of fakeroot or sudo , which is left to the script developer.

It is sometimes useful to apply extra patches to packages - on top of those provided in Buildroot. This might be used to support custom features in a project, for example, or when working on a new architecture. For information about how patches are applied for a package, see Section It can be used to specify a patch directory for any package in buildroot. It should also be used in place of the custom patch directory options that are available for packages such as U-Boot and Barebox.

By doing this, it will allow a user to manage their patches from one top-level directory. In general, any new package should be added directly in the package directory and submitted to the Buildroot upstream project.

How to add packages to Buildroot in general is explained in full detail in Chapter 18, Adding new packages to Buildroot and will not be repeated here. However, your project may need some proprietary packages that cannot be upstreamed. This section will explain how you can keep such project-specific packages in a project-specific directory.

If you are using the br2-external tree feature see Section 9. However, Buildroot will not be aware of the packages in this location, unless we perform some additional steps. As explained in Chapter 18, Adding new packages to Buildroot , a package in Buildroot basically consists of two files: a. mk file describing how to build the package and a Config. in file describing the configuration options for this package. Buildroot will automatically include the.

If we want Buildroot to include. mk file in a first-level subdirectory that includes these additional. mk files. For the Config. in that includes the Config. in files of all your packages. An exhaustive list has to be provided since wildcards are not supported in the source command of kconfig.

For example:. in , preferably in a company-specific menu to make merges with future Buildroot versions easier. If using a br2-external tree, refer to Section 9.

Earlier in this chapter, the different methods for making project-specific customizations have been described. This section will now summarize all this by providing step-by-step instructions to storing your project-specific customizations.

Clearly, the steps that are not relevant to your project can be skipped. config as far as they are relevant :. This chapter discusses how various things are integrated at system level.

Buildroot is highly configurable, almost everything discussed here can be changed or overridden by rootfs overlay or custom skeleton configuration. Systemd requires a DBus daemon. At least one of them must be chosen. If both are included in the configuration, dbus-broker will be used as system bus, but the traditional dbus-daemon is still installed as well and can be used as session bus.

Also its tools e. dbus-send can be used systemd itself has busctl as an alternative. In addition, the traditional dbus package is the only one that provides libdbus , which is used by many packages as dbus integration library.

Both in the dbus and in the dbus-broker case, the daemon runs as user dbus. The DBus configuration files are also identical for both. To make sure that only one of the two daemons is started as system bus, the systemd activation files of the dbus package dbus. socket and the dbus. service symlink in multi-user. wants are removed when dbus-broker is selected. SELinux is a Linux kernel security module enforcing access control policies.

In addition to the traditional file permissions and access control lists, SELinux allows to write rules for users or processes to access specific functions of resources files, sockets…. To have proper support for SELinux in a Buildroot generated system, the following configuration options must be enabled:. The SELinux refpolicy contains modules that can be enabled or disabled when being built. Each module provide a number of SELinux rules.

In Buildroot the non-base modules are disabled by default and several ways to enable such modules are provided:. Buildroot also allows to completely override the refpolicy.

This allows to provide a full custom policy designed specifically for a given system. When going this way, all of the above mechanisms are disabled: no extra SElinux module is added to the policy, and all the available modules within the custom policy are enabled and built into the final binary policy.

The custom policy must be a fork of the official refpolicy. In order to fully override the refpolicy the following configuration variables have to be set:. If the boot process seems to hang after the following messages messages not necessarily exactly similar, depending on the list of packages selected :.

In order to have the system start a shell on your serial console, you have to go into the Buildroot configuration, in System configuration , modify Run a getty login prompt after boot and set the appropriate port and baud rate in the getty options submenu. It has been decided that support for the native compiler on the target would be stopped from the Buildroot If you need a compiler on your target anyway, then Buildroot is not suitable for your purpose.

In such case, you need a real distribution and you should opt for something like:. Since there is no compiler available on the target see Section Because Buildroot mostly targets small or very small target hardware with limited resource onboard CPU, ram, mass-storage , it does not make sense to waste space with the documentation data. If you need documentation data on your target anyway, then Buildroot is not suitable for your purpose, and you should look for a real distribution see: Section To know more about the dependencies of a package, search for the package symbol in the config menu see Section 8.

Then, you may have to recursively enable several options which correspond to the unmet dependencies to finally be able to select the package. If the package is not visible due to some unmet toolchain options, then you should certainly run a full rebuild see Section 8.

There are plenty of reasons to not use the target directory a chroot one, among these:. For these reasons, commands run through chroot, using the target directory as the new root, will most likely fail. One feature that is often discussed on the Buildroot list is the general topic of "package management". To summarize, the idea would be to add some tracking of which Buildroot package installs what files, with the goals of:.

In general, most people think it is easy to do: just track which package installed what and remove it when the package is unselected.

However, it is much more complicated than that:. For all these reasons, the conclusion is that adding tracking of installed files to remove them when the package is unselected, or to generate a repository of binary packages, is something that is very hard to achieve reliably and will add a lot of complexity.

Since Buildroot often involves doing full rebuilds of the entire system that can be quite long, we provide below a number of tips to help reduce the build time:. All of the end products of Buildroot toolchain, root filesystem, kernel, bootloaders contain open source software, released under various licenses.

Using open source software gives you the freedom to build rich embedded systems, choosing from a wide range of packages, but also imposes some obligations that you must know and honour. Some licenses require you to publish the license text in the documentation of your product. Others require you to redistribute the source code of the software to those that receive your product. The exact requirements of each license are documented in each package, and it is your responsibility or that of your legal office to comply with those requirements.

To make this easier for you, Buildroot can collect for you some material you will probably need. To produce this material, after you have configured Buildroot with make menuconfig , make xconfig or make gconfig , run:. There you will find:. Please note that the aim of the legal-info feature of Buildroot is to produce all the material that is somehow relevant for legal compliance with the package licenses.

Buildroot does not try to produce the exact material that you must somehow make public. Certainly, more material is produced than is needed for a strict legal compliance.

For example, it produces the source code for packages released under BSD-like licenses, that you are not required to redistribute in source form. Moreover, due to technical limitations, Buildroot does not produce some material that you will or may need, such as the toolchain source code for some of the external toolchains and the Buildroot source code itself. When you run make legal-info , Buildroot produces warnings in the README file to inform you of relevant material that could not be saved.

Finally, keep in mind that the output of make legal-info is based on declarative statements in each of the packages recipes. The Buildroot developers try to do their best to keep those declarative statements as accurate as possible, to the best of their knowledge. However, it is very well possible that those declarative statements are not all fully accurate nor exhaustive.

You or your legal department have to check the output of make legal-info before using it as your own compliance delivery. See the NO WARRANTY clauses clauses 11 and 12 in the COPYING file at the root of the Buildroot distribution. Buildroot itself is an open source software, released under the GNU General Public License, version 2 or at your option any later version, with the exception of the package patches detailed below.

However, being a build system, it is not normally part of the end product: if you develop the root filesystem, kernel, bootloader or toolchain for a device, the code of Buildroot is only present on the development machine, not in the device storage.

Nevertheless, the general view of the Buildroot developers is that you should release the Buildroot source code along with the source code of other packages when releasing a product that contains GPL-licensed software.

This is because the GNU GPL defines the " complete source code " for an executable work as " all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable ". Buildroot is part of the scripts used to control compilation and installation of the executable , and as such it is considered part of the material that must be redistributed.

Keep in mind that this is only the Buildroot developers' opinion, and you should consult your legal department or lawyer in case of any doubt.

Buildroot also bundles patch files, which are applied to the sources of the various packages. Those patches are not covered by the license of Buildroot. Instead, they are covered by the license of the software to which the patches are applied. When said software is available under multiple licenses, the Buildroot patches are only provided under the publicly accessible licenses. See Chapter 19, Patching a package for the technical details. To achieve NFS-boot, enable tar root filesystem in the Filesystem images menu.

To build a live CD image, enable the iso image option in the Filesystem images menu. Note that this option is only available on the x86 and x architectures, and if you are building your kernel with Buildroot.

You can build a live CD image with either IsoLinux, Grub or Grub 2 as a bootloader, but only Isolinux supports making this image usable both as a live CD and live USB through the Build hybrid image option. As mentioned above, Buildroot is basically a set of Makefiles that download, configure, and compile software with the correct options. It also includes patches for various software packages - mainly the ones involved in the cross-compilation toolchain gcc , binutils and uClibc.

There is basically one Makefile per software package, and they are named with the. mk extension. Makefiles are split into many different parts. Overall, these coding style rules are here to help you to add new files in Buildroot or refactor existing ones.

If you slightly modify some existing file, the important thing is to keep the consistency of the whole file, so you can:. in files contain entries for almost anything configurable in Buildroot. The Config. in files are the input for the configuration tool used in Buildroot, which is the regular Kconfig. Header: The file starts with a header. It contains the module name, preferably in lowercase, enclosed between separators made of 80 hashes.

A blank line is mandatory after the header:. Note that commands inside a define block should always start with a tab, so make recognizes them as commands. cfg files contain the output image layout that genimage utility uses to create final. img file. The genimage. cfg files are the input for the genimage tool used in Buildroot to generate the final image file i. The documentation uses the asciidoc format. Buildroot contains basic configurations for several publicly available hardware boards, so that users of such a board can easily build a system that is known to work.

You are welcome to add support for other boards to Buildroot too. To do so, you need to create a normal Buildroot configuration that builds a basic system for the hardware: internal toolchain, kernel, bootloader, filesystem and a simple BusyBox-only userspace. No specific package should be selected: the configuration should be as minimal as possible, and should only build a working basic BusyBox system for the target platform.

You can of course use more complicated configurations for your internal projects, but the Buildroot project will only integrate basic board configurations. This is because package selections are highly application-specific.

Once you have a known working configuration, run make savedefconfig. This will generate a minimal defconfig file at the root of the Buildroot source tree. If the configuration is a bit more complicated, it is nice to manually reformat it and separate it into sections, with a comment before each section. Typical sections are Architecture , Toolchain options typically just linux headers version , Firmware , Bootloader , Kernel , and Filesystem.

Always use fixed versions or commit hashes for the different components, not the "latest" version. It is recommended to use as much as possible upstream versions of the Linux kernel and bootloaders, and to use as much as possible default kernel and bootloader configurations.

If they are incorrect for your board, or no default exists, we encourage you to send fixes to the corresponding upstream projects. However, in the mean time, you may want to store kernel or bootloader configuration or patches specific to your target platform. You can then store your patches and configurations in these directories, and reference them from the main Buildroot configuration. Refer to Chapter 9, Project-specific customization for more details.

Before submitting patches for new boards it is recommended to test it by building it using latest gitlab-CI docker container. This section covers how new packages userspace libraries or applications can be integrated into Buildroot. It also shows how existing packages are integrated, which is needed for fixing issues or tuning their configuration. When you add a new package, be sure to test it in various conditions see Section First of all, create a directory under the package directory for your software, for example libfoo.

Some packages have been grouped by topic in a sub-directory: x11r7 , qt5 and gstreamer. If your package fits in one of these categories, then create your package directory in these. New subdirectories are discouraged, however. For the package to be displayed in the configuration tool, you need to create a Config file in your package directory.

There are two types: Config. in and Config. For packages used on the target, create a file named Config. This file will contain the option descriptions related to our libfoo software that will be used and displayed in the configuration tool. It should basically contain:. The bool line, help line and other metadata information about the configuration option must be indented with one tab.

The help text itself should be indented with one tab and two spaces, lines should be wrapped to fit 72 columns, where tab counts for 8, so 62 characters in the text itself. The help text must mention the upstream URL of the project after an empty line. You can look at examples in other packages. The syntax of the Config. in file is the same as the one for the kernel Kconfig file. in or in a category subdirectory if you decided to put your package in one of the existing categories.

The files included there are sorted alphabetically per category and are NOT supposed to contain anything but the bare name of the package. The host package should be explicitly selectable by the user from the configuration menu. In this case, create a Config.

host file for that host package:. The same coding style and options as for the Config. in file are valid. The files included there are sorted alphabetically and are NOT supposed to contain anything but the bare name of the package.

The host package will then be available from the Host utilities menu. in file of your package must also ensure that dependencies are enabled. Typically, Buildroot uses the following rules:. The current problem with the kconfig language is that these two dependency semantics are not internally linked. An example illustrates both the usage of select and depends on. Overall, for package library dependencies, select should be preferred.

Note that such dependencies will ensure that the dependency option is also enabled, but not necessarily built before your package. To do so, the dependency also needs to be expressed in the. mk file of the package. Further formatting details: see the coding style. Some packages can only be built on certain target architectures, or if an MMU is available in the processor.

These dependencies have to be expressed with the appropriate depends on statements in the Config. in file. Additionally, for dependencies on toolchain options, a comment should be displayed when the option is not enabled, so that the user knows why the package is not available. Dependencies on target architecture or MMU support should not be made visible in a comment: since it is unlikely that the user can freely choose another target, it makes little sense to show these dependencies explicitly.

The comment should only be visible if the config option itself would be visible when the toolchain option dependencies are met. This means that all other dependencies of the package including dependencies on target architecture and MMU support have to be repeated on the comment definition.

There is no external source of money in the binary trading platforms. The money is being rotated. One trader won while the other lost. The money lost by that trader will get transferred to the one that won, depending on the profit percentage given by the broker to its traders.

Some percentage of the money lost will go to the broker. The answer to this question depends on the amount of money being traded. However, if you fail, you will lose all your money, i. There is no fixed maximum amount that can be earned through trading options. It depends on the amount of money traded and the number of wins. Since the trading strategies only give you a signal to predict your next move. However, good practice and knowledge of the asset will increase your chances to win.

To succeed in binary option trading, in the long run, you must practice the strategies repeatedly. Along with using the strategies, you must have patience and avoid taking impulsive actions. Using any strategy for one time will not bring you profits. Testing, trying, and repeating are the only way to master trading tactics.

Do not quit a strategy and opt for a new one every time you experience a loss. This will only confuse you, and you will never be able to make the best out of one strategy. Instead, stick to one strategy and learn the right time to use it.

It is also important to figure out the time when you must avoid using certain strategies. However, if your strategy is not working, you must reconsider it and make a new one. Now that you have read some of the best binary option trading strategies, find the one you have understood well and test it today. Then, get into action and start making money today!
