[Mono-dev] threads.o : fatal error: error in backend: unsupported symbol modifier in relocation

[Robert N]

I tried to compile from the tarball (mono-3.2.0.tar.bz2) and got the same results on OS-X. Is this a tool dependency related error? 

Is there at list of tool versions that are required to build 3.2.x on OS-X?

The OS-X Compile page lists autoconf/automake/libtool/m4 with versions. Are there different tool dep list for each mono version? What about clang/llvm version issues?

Thanks for any help on this.

> I am trying to compile version 3.2.0 of mono for a compliance review on OS-X (git checkout mono-3.2.0) and I'm receiving a fatal error on threads.o and domain.o during the 'make' run. Diving into libmonoruntime_la-threads.lo and/or libmonoruntime_la-domain.lo, I am getting a clang/llvm fatal error of "error in backend: unsupported symbol modifier in relocation". I've also tried checking out git tags 3.2.1, 3.2.3, etc.. and the same error occurs, Also tried x32 vs x64 builds, same error. FYI: building the latest 4.x branches/tags work fine.
