Hi Cristian,
thanks for the replay. I have clang-cl first in PATH, the problem persists.
$ SET PATH
Path=D:\-Work-\llvm-3.7.1.src\-VS_build VS 2013-\Release\bin;...
$cd D:\-Work-\llvm-3.7.1.src\-VS_build VS 2013-\Release\bin

Hi Anton,
clang.exe doesn't know of any windows specific things. Clang-cl
instead does.
Just make sure to have clang-cl before msvc-cl in path and ninja will
just work.
Cheers,
Cristian

Hi all,
I'm trying to use Clang, compiled with VS 2013
(configuration:Release, platform:x64) as a C/C++ compiler for a
simple HelloWorld CMake project. Generation ends up with errors
like "clang.exe: error: no such file or directory: '/DWIN32'" at
compiler check stage. If I understand correctly the problem is
that MSVC compiler options are fed to Clang for some reason (maybe
the "-- The C compiler identification is unknown" log entry is
related to the problem?).
Could anyone help to resolve this, please?
I also tried to change compiler ID with
"-DCMAKE_C_COMPILER_ID=Clang -DCMAKE_CXX_COMPILER_ID=Clang", then
compilation succeeded, but linkage failed (just as described in
the thread "Question on usage of cmake on Windows with clang"
http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/54650).
Here the problem seems to be reversed: GNU linker options are fed
to MS linker.
************** Setup and details:
1) INCLUDE and PATH set to clang/clang-cl
2) command line environment is configured with vsvars32.bat
3) CC and CXX set to clang
$ cat CMakeLists.txt
project(test_project)
add_executable(main file.cpp)
$ cmake -G "Ninja" -DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang ..
Log:
-- The C compiler identification is unknown
-- The CXX compiler identification is Clang 3.7.1
-- Check for working C compiler using: Ninja
-- Check for working C compiler using: Ninja -- broken
