After figuring out the fault in the configuration step and rebuilding,
and then rebuilding again by forcing it with `ninja -k 16`, I managed to
build everything but 12 ninja targets.
I have to sift through them before I can report more, and I don't
don't know if it's small enough to post here, but some of the more
interesting errors are:
llvm/projects/compiler-rt/lib/tsan/dd/dd_interceptors.cc:226:20:
error: redefinition of 'realpath'
INTERCEPTOR(char*, realpath, const char *path, char *resolved_path) {

Looks like bits/stdlib.h gets pulled in only when _FORTIFY_SOURCE is enabled (which causes __USE_FORTIFY_LEVEL > 0). Do you have _FORTIFY_SOURCE set somewhere? Can you try with that not set?

Do you have _FORTIFY_SOURCE > set somewhere?I do, it's by default a part of hardening flags on most Linux distros, and I'm just following what the distro packages are built with.> Can you try with that not set?I can try, but I would prefer not to since it's a wide-spread default in Linux distro as part of stack-protector use. I would use SafeStack but that's limited in applicability right now. If I did we would still have the libomp duplicate symbol error. Since 3.9.0 built fine with that macro, I'd blame either gcc or glibc headers or compiler-rt 3.9.1. Arch Linux's 3.9.1 recipe applies the following patch: https://git.archlinux.org/svntogit/packages.git/tree/trunk/msan-prevent-initialization-failure-with-newer-glibc.patch?h=packages/llvm all the files https://git.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/llvm&id=a7dd5d50ec82d6a35a99f9bf92b074d4aeab1f50
