我正在尝试使用 CMake 作为主要构建工具在 Windows 机器上构建一个简单的应用程序。一旦在项目上调用 CMake,配置阶段就会出错:

r.cmake:52 (message):
The C compiler

It fails with the following output:

我通过网络阅读了很多内容,但任何建议的解决方案都没有解决我的问题。到目前为止,我发现的是一个类似但可能已经过时的相同问题的解决方案,这对我不起作用,因为 Ninja 无法构建可执行文件:
> ninja all

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.d'
ninja: build stopped: subcommand failed.
在此错误之前,CMake 配置正确,除了所有编译器 ABI 信息检测失败 - 但 CMake 恢复没有错误。还有一些 其他问题也没有帮助。
官方文档说这很简单,但实际上并非如此。
那么:如何使用带有 Ninja 生成器和 Clang 作为编译器的 CMake 构建一个简单的C++ 项目?我尽量避免安装 Visual Studio,但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
- 铿锵声 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)
主文件
#include <stdio.h>
int main(void)
{
printf("Hello World!\n");
return 0;
}
