使用Ninja Generator的Windows(clang-cl)CMake构建

我正在尝试使用CMake作为主要构建工具在Windows计算机上构建一个简单的应用程序。在项目上调用CMake后,在配置阶段就会出错:

> cmake -H. -G Ninja -Bbuild -DCMAKE_C_COMPILER:PATH="C:\Program Files\LLVM\bin\clang-cl.exe" -DCMAKE_CXX_COMPILER:PATH="C:\Program Files\LLVM\bin\clang-cl.exe"

  It fails with the following output:

我在网上读了很多东西,但是我的问题没有被任何提议的解决方案解决。到目前为止,我发现的是一个类似的词,但可能由于类似的问题solution已过时,该问题对我不起作用,因为Ninja无法生成可执行文件:

> ninja all
[1/2] Building CXX object CMakeFiles/minimal.dir/main.cpp.obj
FAILED: CMakeFiles/minimal.dir/main.cpp.obj
C:\PROGRA~1\LLVM\bin\clang-cl.exe     -MD -MT CMakeFiles/minimal.dir/main.cpp.obj -MF CMakeFiles\minimal.dir\main.cpp.obj.d -o CMakeFiles/minimal.dir/main.cpp.obj -c ../main.cpp
clang-cl.exe: warning: unknown argument ignored in clang-cl: '-MF' [-Wunknown-argument]
clang-cl.exe: error: no such file or directory: 'CMakeFiles/minimal.dir/main.cpp.obj'
clang-cl.exe: error: no such file or directory: 'CMakeFiles\minimal.dir\main.cpp.obj.d'
ninja: build stopped: subcommand failed.

在此错误之前,CMake已正确配置,但所有编译器ABI信息检测均失败-但CMake继续正常运行,没有错误。有some other个问题也无济于事。

documentation官员表示这很简单,但实际上并非如此。

所以:如何使用带有Ninja生成器和Clang作为编译器的CMake构建简单 C ++项目?我尝试避免安装Visual Studio,但是如果生成的二进制文件与MSVC构建二进制文件兼容,那就太好了。

版本:

  • CMake 3.12.2
  • 忍者1.8.2
  • C 7.0.0

示例:这是我正在使用的最小示例:

CMakeLists.txt

cmake_minimum_required(VERSION 3.12)
project(minimal)
add_executable(${PROJECT_NAME} main.cpp)

main.cpp

#include <stdio.h>

int main(void)
{
  printf("Hello World!\n");
  return 0;
}

答案 0 :(得分:3)

要使用 clang-cl 进行编译,必须在加载了MSVC环境的情况下运行 cmake (使用 vcvarsall.bat )。否则,它将尝试使用GCC兼容性选项。 仅安装Build Tools就足够了。
