[vlc-devel] [PATCH] configure: disable -z defs linker check for OpenBSD.

[Brad Smith]

libvlccore will fail linking..

This is expected for OpenBSD. You cannot use -z,defs
when linking shared libraries if any of the code utilizes
functions from libc since shared libraries are not linked
against libc.
