[LLVMdev] amd64, FreeBSD and shared libraries

[Coleman Kane]

Hello,

I am trying to build llvm-gcc 4.2 w/ llvm 2.2 on FreeBSD/amd64 and have
found that it doesn't seem to want to build shared libraries. I've found
numerous notes that I should try --disable-shared, because the linker
ends up erroring out with a linker error when building libgcc_s.so.
Subsequently, the same error is produced when it attempts to build
libstdc++.so. If you do happen to build and install it, any attempt to
link a shared library results in this very same behavior. The
crtbeginS.o object seems to contain the offending relocation data which
ld doesn't like.

The following error is what I get:

I am really eager to get this working on my system so that I can play
around. Any help would be appreciated.
