r241432 - Teach mingw toolchain the msys2 mingw-w64 distribution C++ dirs.

Sun Jul 12 06:31:28 PDT 2015

clang does call ld directly and needs to know libs directories. Calling gcc
may solve the link problem but clang would still have to find the include
dirs somehow.
You solved this problem with -isystem
/usr/x86_64-w64-mingw32/sys-root/x86_64-w64-mingw32/include but there are
additional C++ includes.

The root of the problem is x86_64-w64-mingw32-gcc is in /usr/bin but includes
and libs under /usr/lib64/gcc/x86_64-w64-mingw32/5.1.0. So
x86_64-w64-mingw32-gcc is not in the same subtree as its includes and libs.

Is that standard installation of mingw?
Any idea how clang can find out these /usr/lib64/gcc/x86_64-w64-mingw32/5.1.0
 dirs?
How about using --sysroot=/usr/lib64/gcc/x86_64-w64-mingw32/5.1.0 ?
