Extended Description

Following the instructions on http://clang.llvm.org/get_started.html I've taken all the steps, even the optional ones, for linux.

At step 7, make fails when trying to link ../../lib/libc++.so because of undefined references such as: __cxa_guard_acquire

I've attached the (stdout & stderr) output from make using make &> llvm_make_error.txt

Cmake output seems fine, attached that as well.

I've done a fresh install of debian and reproduced the problem here too:

Linux serenity 3.16.0-4-amd64 #​1 SMP Debian 3.16.7-ckt25-2 (2016-04-08) x86_64 GNU/Linux

The error message is the same but let me know if it helps to attach the one from this machine as well.

I also find it highly suspicious that after following the installation instructions, my svn status is this:

?       projects/compiler-rt
?       projects/libcxx

Does anyone look at these bug reports?

Yes, but you have to be rather patient.
