[erlang-bugs] epmd_srv.c:(.text+0x830): undefined reference to `sd_listen_fds'

[Dirkjan Ochtman]

Building Erlang 17.0 on Gentoo systems (I am the packager there),
there have been some problems:

epmd_srv.c:(.text+0x830): undefined reference to `sd_listen_fds'

I looked at configure --help, but there doesn't seem to be anything
about systemd in there. However, I found references to systemd in e.g.
erts/configure.in. In Gentoo, we prefer to be explicit about
supporting installed libraries, so I wonder if there could be a
--disable/enable-systemd switch to configure, so that this can be
explicitly stated at configure time.

Cheers,
