ejabberd
In this guide we are using the plain meta-erlang layer to build a XMPP server called ejabberd.
The recipe ejabberd_20.03.bb builds the ejabberd using a crosscompile approach both to erlang and for the various Erlang NIFs. ejabberd uses a custom mix between autotools and rebar2. Basically rebar needs to know how to use the correct environment variables in order to compile all the C code.
As a final result, we are able to run an embedded ejabberd using qemu.
Follow the quickstart guide to get a basic working environment and then:
- Add
ejabberd
package toIMAGE_INSTAL
in conf/local.conf
echo 'IMAGE_INSTALL:append = " ejabberd"' >> conf/local.conf
- Now its time to build the image:
bitbake core-image-minimal
- And check the results with qemu:
runqemu core-image-minimal
Connect to the qemu instance and call the main ejabberd admin tool:
ejabberdctl
.
The default recipe creates a system user called ejabberd by default.
