[Pkg-erlang-devel] Bug#961596: rebar: Remove -lerl_interface from ERL_LDFLAGS for Erlang 23

[Sergei Golovan]

Package: rebar
Version: 2.6.4-2
Severity: normal

Dear Maintainer,

I'd like to upload Erlang 23 to Debian for bullseye, so we'll need to make
its reverse dependencies working.

One of the changes in Erlang 23 is removal of an outdated erl_interface
library.

Rebar adds '-lerl_interface' to ERL_LDFLAGS, which means that packages will
start FTBFS complaining about non-existing library (for example the esdl
package doesn't use erl_interface, but still FTBFS with Erlang 23 because of
rebar's trying to link it in).

I'd suggest to remove -lerl_interface from the default rebar config. Packages
that really depend on it will have to adjust anyway.
