Missing erlang dependency

[wlindauer]

It appears that when compiling elixir it requires erlang to have already been built. The elixir and elixir-native recipes seem to be missing DEPENDS += "erlang" and DEPENDS += "erlang-native" respectively.

Shouldn't the RDEPENDS handle this also?
RDEPENDS is necessary because erlang is also needed at runtime on the target platform. Is a DEPENDS needed in addition to the RDEPENDS?

[wlindauer]

Unfortunately no, the RDEPENDS is not a superset of DEPENDS. Yes, you will need both DEPENDS and RDEPENDS. The RDEPENDS only insures that erlang will be built and placed in the final image to satisfy the need at runtime. It does not, however, guarantee any ordering during the build. In my scenario, it was attempting to build erlang and elixir in parallel instead of first building erlang and then building elixir in serial. Hopefully that explanation helps.

Thanks for helping

Yes, that would be good.
