            Bug ID: 21384
           Summary: Can't build compiler-rt as part of llvm
           Product: compiler-rt
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: compiler-rt

I'm trying to build llvm with compiler-rt in the tree, similar to how it is
described at http://clang.llvm.org/get_started.html but using the official
release tarballs instead of svn checkouts.

I'm compiling on a Slackware-current system (the tree leading up to the next
release) using glibc-2.20. I tried working around the error by adding
-I/usr/include to the CFLAGS, but while the compile commands for llvm and clang
picked that up just fine, it's completely ignored by compiler-rt. My next best
guess is that it's failing because stdint.h is missing in SKDs/linux.

This is the error I'm getting:
