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 >= Guppy in the latest machine's deploy directory. (e.g for Guppy in latest/<yourmachine>/deploy/sdk directory)
For the master development branch, in the latest machine's deploy directory. (e.g in latest/<yourmachine>/deploy/sdk directory)

To install the native package please refer to this chapter in the AGL documentation to install the AGL repository for your distribution.

Then use your package manager to install the library.

OpenSuse

sudo zypper ref
sudo zypper install agl-libafb-helpers-devel

Fedora

sudo dnf ref
sudo dnf install agl-libafb-helpers-devel

Ubuntu/Debian

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

# 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

vim .gitmodules

Remove the afb-helpers target link from any CMake target you specified. Those lines look like:

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:

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 CMake command to add it if you don't use the cmake-apps-module
