Hi Cristian,
That's what I did:
1) Created empty directory "D:\CL", moved clang-cl.exe there and renamed
it to cl.exe.
2) Put the paths to cl.exe and Clang first in the global PATH
environment variable. Set path to Clang Includes first in INCLUDE
3) Launched Cmake from an empty project dir.
Still having the same issue. What am I doing wrong? Any ideas?
------ check that project dir is empty:
$dir

Hi Anton,
When I say clang-cl I mean how the official llvm package does it - a
50mb executable named cl.exe and not clang-cl.exe.
Ninja believes it compiles with visual c++, but instead it compiles
with clang. That's why you need to put the path to clang INCLUDE and
PATH first.
Simply rename clang-cl.exe as cl.exe, copy it in a directory and put
that path as first in the PATH environment variable.
Cheers,
Cristian.

Hi Cristian,
thanks for the replay. I have clang-cl first in PATH, the problem
persists.

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 ..
