[cfe-dev] clang libc++ libcxxabi std::thread std::async

[David Irvine]

UPDATE !!

I had to switch to libcxxrt with some hassle (libcxxabi fixed threading but
not async). To get this to statically compile I did have to use the buildit
script in libcxx/lib dir. Adding the -l:libcxxrt.a as LDFLAGS and ifPIC as
compile flags then in EXTRA_FLAGS add -DLIBCXXRT seems to do the trick if
you have libcxxrt.a installed all OK.

then pass -ldl with all builds and it's working.

Thanks again and hope this helps somebody else. If I get a chance I will
check the CMake build in libcxx to see if there's a simple way to add an
option (USE_LIBCXXRT || USE_LIBCXXABI when it's ready)

Thanks again, it's great to be building in clang now ! several hard to find
errors gone already.
