Hello, I am trying to use clang with cmake on Windows.
I have compiled LLVM+clang using Visual Studio 2015. And now I am facing
problems with building cmake projects using this clang. It looks like
cmake is trying to pass wrong options to linker.
Here simple test project:
$ cat CMakeLists.txt
project(test_proj)
add_executable(test
test.cpp
)
$ cat test.cpp
#include <cstdio>
int main() {
printf("Hi there\n");
}
I am trying to build it using the following command:
$ cmake .. -G "Ninja" -DCMAKE_C_COMPILER=clang
-DCMAKE_CXX_COMPILER=clang -DCMAKE_C_COMPILER_ID=Clang
-DCMAKE_CXX_COMPILER_ID=Clang
And it fails with the error:
Run Build Command:"C:/ninja/ninja.exe" "cmTC_a2e93"
[1/2] Building C object CMakeFiles\cmTC_a2e93.dir\testCCompiler.c.obj
[2/2] Linking C executable cmTC_a2e93.exe
FAILED: cmd.exe /C "cd . && C:\Users\del\work\llvm\bin\clang.exe

-Wl,--major-image-version,0,--minor-image-version,0 && cd ."

clang.exe: error: linker command failed with exit code 1181 (use -v
to see
invocation)
ninja: build stopped: subcommand failed.
Here are the details on environment:
os: Windows 7 (64bit)
$ clang --version
clang version 3.9.0
Target: i686-pc-windows-msvc
Thread model: posix
$ cmake --version
cmake version 3.5.0-rc1
It would be great if someone could point me to what am I doing wrong?
Thanks in advance!
