[cfe-dev] Building clang with mingw/msys/gcc 4.4

[Azriel Fasten]

I managed to build clang on mingw/msys today.

Running configure, make install worked for both debug and optimized builds
in general. However there were a few hitches along the way. Make would fail
with:


ln: creating symbolic link
`/d/super/dump/code/llvm/llvm-project/llvm/build.clang/Release+Asserts/bin/clang++.exe'
to `clang.exe': No such file or directory
ln: creating symbolic link `/usr/local/bin/clang++.exe' to `clang.exe': No
such file or directory


And similar errors. Running make with the -i argument finished the build,
and I manually created the links. I don't think there were any other
problems in the build, and

I changed InitHeaderSearch.cpp as instructed for clang to locate the header
files.

clang managed to build my large (personal) project, forcing me to fix some
syntax errors gcc allowed.

Linking ran into a single multiple definition error:

d:/super/dump/mingw/mingw/bin/../lib/gcc/mingw32/4.4.0/libstdc++.a(tinfo.o):C:\MinGW\src\gccbf\mingw32\libstdc++-v3\libsupc++/../../../../gcc-4.4.0/libstdc++-v3/libsupc++/tinfo.cc:40:
multiple definition of `std::type_info::operator==(std::type_info const&)
const'
objs/test/LoadSave.o:fake:(.text$_ZNKSt9type_infoeqERKS_[std::type_info::operator==(std::type_info
const&) const]+0x0): first defined here

This seemed to be defined in the libstdc++, and also in each of my
Translation Units.

I used gcc version 4.4.0 (GCC) and GNU Make 3.81
