3. Installing the Binder Daemon

The Application Framework Binder Daemon (afb-daemon), which is a part of the AGL Application Framework, provides a way to connect applications to required services. It provides a fast way to securely offer APIs to applications that are written in any language and that can run almost anywhere.

You can learn more about the AGL Application Framework in the “AGL Framework Overview” section. You can learn more about the aft-daemon in the “Binder Overview” section.

Installing on Debian

Use the following commands if your native Linux machine uses the Debian distribution:

$ sudo apt-get install agl-app-framework-binder-dev

Installing on OpenSUSE

Use the following commands if your native Linux machine uses the OpenSUSE distribution:

bash $ sudo zypper install agl-app-framework-binder-devel

Installing on Fedora

Use the following commands if your native Linux machine uses the Fedora distribution:

bash $ sudo dnf install agl-app-framework-binder-devel

Setting Your Environment Variables

Regardless of your system’s distribution, you need to set certain environment variables correctly in order to use the daemon (i.e. app-framework-binder).

Commands that define and export these environment variables exist in the /etc/profile.d/AGL_app-framework-binder.sh file, which is created when you install the daemon:

export LD_LIBRARY_PATH=/opt/AGL/lib/x86_64-linux-gnu:${LD_LIBRARY_PATH}
export LIBRARY_PATH=/opt/AGL/lib/x86_64-linux-gnu:${LIBRARY_PATH}
export PKG_CONFIG_PATH=/opt/AGL/lib/x86_64-linux-gnu/pkgconfig:${PKG_CONFIG_PATH}
export PATH=/opt/AGL/bin:${PATH}

You can make sure thest environment variables are correctly set by doing one of the following:

  • Logout and Log Back In:

    Logging out and then logging back in correctly sets the environment variables.

  • Manually Source the AGL_app-framework-binder.sh File:

    Source the following command:

    $ source /etc/profile.d/AGL_app-framework-binder.sh
    

    NOTE: Creating a new session automatically sources the AGL_app-framework-binder.sh file.
