This layer provides support for Erlang and Elixir for use with OpenEmbedded and/or the Yocto Project build system:

See meta-erlang documentation.

This layer depends on:

URI: git://git.openembedded.org/bitbake branch: master

URI: git://github.com/openembedded/oe-core.git branch: master revision: HEAD

URI: git://git.openembedded.org/openembedded-core layers: meta branch: master

For erlang odbc:

URI: https://github.com/openembedded/meta-openembedded.git layers: meta-oe branch: master

For erlang lksctp run-time support:

URI: https://github.com/openembedded/meta-openembedded.git layers: meta-networking branch: master

Use the bitbake-layers add-layer command to add the meta-erlang to the configuration file:

cd ~/poky/build
bitbake-layers add-layer ../meta-erlang

Then run:

bitbake erlang-embedded-image-minimal

That will create an image with embedded erlang.

Or add IMAGE_INSTALL_append = " erlang" in conf/local.conf file and run bitbake core-image-minimal to get an image with erlang support.

Also, there are a set of recipe examples demonstrating how to integrate Erlang/Elixir projects into YP/OE. The examples tried to cover some common use cases when dealing with cross compiled
applications.

meta-erlang tries to support a well balanced range of Erlang, Elixir and Yocto Project versions. The purpose is to provide up-to-date recipes following the latest fixes found in Erlang and Elixir projects as well keeping the old recipes to not break compatibility.

As meta-erlang provides multiple versions for the same recipes, pay attention to configure the variable PREFERRED_VERSION in one of the configuration file like local.conf, site.conf, auto.conf or distro/include files. Like this:

PREFERRED_VERSION_erlang = "23.1.3"
PREFERRED_VERSION_erlang-native = "23.1.3"

PREFERRED_VERSION_elixir = "1.10.0"
PREFERRED_VERSION_elixir-native = "1.10.0"

However if you have any specific requirements for a special recipe version, you can always add it in your application/middleware layer.

Following the OTP Versions Tree, Elixir Compatibility and Deprecations and Yocto Project releases meta-erlang supports the below versions:

Erlang:

• maint-24
• maint-23
• maint-22
• maint-21

Elixir:

• v1.11
• v1.10
• v1.9

Yocto:

• [hardknott]](https://git.yoctoproject.org/cgit/cgit.cgi/poky/log/?h=hardknott)
• gatesgarth
• dunfell
• zeus
• warrior

This layer can provide the entire Erlang installation, from the base runtime (erlang) to a full erlang development environment with all of the bells and whistles (erlang-modules).

A list of all the packages provided can be found in the manifest file, at recipes-devtools/erlang/erlang-${PV}-manifest.inc. This file needs to be re-generated and new SRCREVs need to be added whenever the version hanges.
