Could you please also make sure it builds on FreeBSD, so that I can create the FreeBSD port for it?

Thanks!

This is a problem with a third-party library. I'm not sure we want to patch all of those for FreeBSD; I would accept pull requests though. We have the problem of maintenance; we would need a build system setup to keep testing the target so it doesn't break in the future and it seems all BSD distributions on top of Linux kernels have died so we can't use our docker machines. It might be that would could port OpenModelica to Alpine Linux which uses musl-libc and thus less GNU extensions.

I would like to test some things on that code though because it should work just fine on FreeBSD; for some reason bind(...) returns a function pointer instead of an int? The FreeBSD man pages says it returns an int...
