[cfe-dev] building LLVM/Clang on Windows 7 x64 using MinGW/MSYS

I tried building with the MinGW64 compiler and got a different link error at 64% of the build:
Linking CXX executable ../../bin/lli.exe
../../lib/libLLVMExecutionEngine.a(RTDyldMemoryManager.cpp.obj):RTDyldMemoryManager.cpp:(.text+0x8f): undefined reference to `__register_frame'
collect2.exe: error: ld returned 1 exit status
tools/lli/CMakeFiles/lli.dir/build.make:198: recipe for target `bin/lli.exe' failed
make: *** [bin/lli.exe] Error 1
CMakeFiles/Makefile2:7475: recipe for target `tools/lli/CMakeFiles/lli.dir/all' failed
make: *** [tools/lli/CMakeFiles/lli.dir/all] Error 2
Makefile:136: recipe for target `all' failed
make: *** [all] Error 2
So I went back and tried the 32 bit tools again. I got the same failure, but I noticed that ld.exe was only using 1.97 GB of ram when it crashed, so I'm not sure the problem is an address space issue.
I will be busy with moving for a few days, but any other ideas are welcome.

3GB is too close for comfort for the 32 bit linker.
G M reports success with the 64 bit toolchain so maybe it's actually required with current versions.
Are you using the 32-bit toolchain or 64-bit toolchain of mingw-builds?

I also had some problems with building llvm+clang on MinGW 4.8.1 + MSYS. Another thing was that linker did require ~3GB memory to complete on x64.
Here in the readme I have listed steps and linked versions of MinGW and MSYS to use for being able to compile llvm + clang on Windows 7.
Best regards, Mikael Lepistö

I'd try switching MingW distribution as it's very easy to do.
If you're now using http://www.mingw.org/ try http://sourceforge.net/projects/mingwbuilds/ and vice verse. These are different distributions with different patches and different binaries.
For instance ld.exe in the former is 9MB and in the later 944K.
