# Usage ## Installation The afb-helpers library is integrated by default in the AGL SDK since the Guppy version (>=7) and is also available as a package for the AGL supported linux distributions. You could find the SDK build from Yocto which embed the afb-helpers library here: * For the [releases](https://download.automotivelinux.org/AGL/release/) >= Guppy in the latest machine's deploy directory. (e.g for Guppy in `latest//deploy/sdk` directory) * For the [master](https://download.automotivelinux.org/AGL/snapshots/master/) development branch, in the latest machine's deploy directory. (e.g in `latest//deploy/sdk` directory) To install the native package please refer to [this chapter](../1-verify-build-host.html) in the AGL documentation to install the AGL repository for your distribution. Then use your package manager to install the library. ### OpenSuse ```bash sudo zypper ref sudo zypper install agl-libafb-helpers-devel ``` ### Fedora ```bash sudo dnf ref sudo dnf install agl-libafb-helpers-devel ``` ### Ubuntu/Debian ```bash sudo apt-get update sudo apt-get install agl-libafb-helpers-dev ``` ## (Optionnal) Remove the git submodule version If you already use the afb-helpers component but using the submodule version then you have to get rid of it to be sure to link and use the library version. To do so, you have to do the following: * Deinitialize the submodule using `git` ```bash # This example assumes that the git submodule is named app-afb-helpers-submodule # and is located at your root project repository. git submodule deinit app-afb-helpers-submodule ``` * Remove the submodule relatives lines from the `.gitmodules` file ```bash vim .gitmodules ``` * Remove the `afb-helpers` target link from any CMake target you specified. Those lines look like: ```bash TARGET_LINK_LIBRARIES(${TARGET_NAME} afb-helpers # REMOVE THIS LINE ${link_libraries} ) ``` ## Add the libafb-helpers as a static library to your binding In your `config.cmake` file, add a dependency to the controller library, i.e: ```cmake set(PKG_REQUIRED_LIST json-c afb-daemon afb-helpers --> this is the afb-helpers library dependency name. ) ``` Or you can also use the [FIND_PACKAGE](https://cmake.org/cmake/help/v3.6/command/find_package.html?highlight=find_package) CMake command to add it if you don't use the [cmake-apps-module](../cmakeafbtemplates/dev_guide/cmake-overview.html)
