<p dir="ltr">Hi Anton,</p>
<p dir="ltr">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.</p>
<p dir="ltr">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.</p>
<p dir="ltr">Simply rename clang-cl.exe as cl.exe, copy it in a directory and put that path as first in the PATH environment variable.</p>

thanks for the replay. I have clang-cl first in PATH, the problem
persists.<br>

<br>
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?).<br>
Could anyone help to resolve this, please?<br>
<br>
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" <a href="http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/54650" rel="noreferrer" target="_blank">http://thread.gmane.org/gmane.comp.programming.tools.cmake.user/54650</a>).
Here the problem seems to be reversed: GNU linker options are
fed to MS linker.<br>
<br>
************** Setup and details:<br>
1) INCLUDE and PATH set to clang/clang-cl<br>
2) command line environment is configured with vsvars32.bat<br>
3) CC and CXX set to clang<br>
<br>
$ cat CMakeLists.txt<br>
project(test_project)<br>
add_executable(main file.cpp)<br>
<br>
$ cmake -G "Ninja" -DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang ..<br>
<br>
Log:<br>
-- The C compiler identification is unknown<br>
-- The CXX compiler identification is Clang 3.7.1<br>
-- Check for working C compiler using: Ninja<br>
-- Check for working C compiler using: Ninja -- broken<br>
