Linker “error: cannot preempt symbol” when building openal-soft

[ssterling]

I've tried everything I can from a Google search of “cannot preempt symbol” (try it yourself; only 22 results). No luck after three hours. The ports version of openal-soft builds just fine for me, though.

I'm on FreeBSD 12.0-RELEASE, amd64.

Try env LDFLAGS=-fuse-ld=bfd ./build.sh

Works!
