Here's the patches that makes everything works... patch-configure.in : this fixes pthread at several places and ensure LLVM_ variables have a sed -e to replace lpthread to pthread patch-eglib_src_Makefile.am : there's an issue with the NEED_VASPRINTF detection i commented the fix to keep foo.c ; definitively not the place ... patch-mcs_class_System_System.IO_KeventWatcher.cs: old patch for keven from romain.tarti...@gmail.com mono maintainer (bsd-sharp) patch-mono_dis_util.c : there's a problem with HAVE_ISINF detection ; flushed the pragma here... definitively not the place ...
patch-mono_mini_mini-llvm.c : The important patch - mini-llvm.c contains
gsharevt code and libmono-llvm.so doesn't link it, since it's just returning
false, i readded the functions locally... also mono_print_unwind_info is not
linked from unwind.o and adding it pull up recursive dependency...
I am including romain tartiere to keep him in the loop if he wants to check
those patches in bsd-sharp repo...
I don't say those patches are ok, to the contrary, i say those a hints at what
is to be really fixed for FreeBSD...
there's still code pointing to libc.so instead of @LIBC@
but this fix the issues:
ln -s /lib/libc.so.7 /lib/libc.so

We'd love to merge such change for FreeBSD :)

Good news, i figured out why it was hanging with llvm.
It's seems part of the code is missing -pthread and/or using -lpthread
CFLAGS+= -pthread
CXXFLAGS+= -pthreadLDFLAGS+= -pthread
it seems llvm-config output -lpthread and not -pthreadreplace -lpthread to
-pthread in LLVM_CFLAGSreplace -lpthread to -pthread in LLVM_LIBS
I don't know if someone is willing to see this in mono source or to keep it as
external patch?

LLVM was never tests on FreeBSD, you'll have to debug it.

When I try to compile mono from git with llvm ; llvm installed from
github.com/mono/llvm
I'm on FreeBSD HEAD.
Everything compiles smoothly but now the mono-sgen process get stuck in
"umtxn" state (kernel lock) on the first usage. (basic-profile-check.exe)
Whenever i remove --enable-llvm everything is fine again. This was working
before around october. Any ideas what could have change to cause this?
Any suggestions where to look?
Thanks.
