[LLVMdev] Building Compiler-RT on Windows

[Daniel Dilts]

Has anyone built Compiler-RT on Windows?  I am attempting to compile it for
ARM, but I get errors from CMake.  It appears to be trying to pass VC++
flags to Clang.  I am using a version of Clang built from trunk.



PS D:\llvm\arm_test\compiler-rt-build> cmake -G Ninja
-DCMAKE_C_COMPILER=clang.exe -DCMAKE_CXX_COMPILER=clang++.exe -DCM
AKE_RC_COMPILER=rc.exe -DCMAKE_CXX_FLAGS="" -DCMAKE_C_FLAGS=""
