Building runtime

The beamruntime user guide has more details about how to setup and usage modes.

This section is focused on how to build beamruntime using meta-erlang.

beamruntime-tarball recipe

The first step is to define which Erlang and Elixir versions the beamruntime will use. This is done configuring the following variables in the file conf/local.conf or in the distro configuration file:

PREFERRED_VERSION_erlang = "24.1.7"
PREFERRED_VERSION_erlang-native = "24.1.7"
PREFERRED_VERSION_nativesdk-erlang = "24.1.7"

PREFERRED_VERSION_elixir = "1.12.3"
PREFERRED_VERSION_elixir-native = "1.12.3"
PREFERRED_VERSION_nativesdk-elixir = "1.12.3"

Then, make sure opengl feature is not configured. By defaul beamruntime enables wx Erlang application:

# disble opengl for beamruntime
DISTRO_FEATURES_FILTER_NATIVESDK:remove = "opengl"

After that, the next step is to call bitbake to build the beamruntime tarball:

bitbake beamruntime-tarball

Once the build has finished, the results can be found at tmp/deploy/sdk folder. You can copy it to the development machine. The installation is done executing the .sh script, like that:

sh x86_64-beamruntime-nativesdk-standalone-3.4.1-erlang-24.1.7-elixir-1.12.3.sh
