无法在 MSys2 上通过 cmake 编译项目
Not able to compile project by cmake on MSys2
问:
我正在通过教程学习使用 CMake:http://derekmolloy.ie/hello-world-introductions-to-cmake/。我尝试使用 cmake 编译我的hello_world.cpp,但我在 Windows 10 的 MSys2 上收到此错误消息:
-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:3 (project):
The CMAKE_C_COMPILER:
cl
is not a full path and was not found in the PATH.
To use the NMake generator with Visual C++, cmake must be run from a shell
that can use the compiler cl from the command line. This environment is
unable to invoke the cl compiler. To fix this problem, run cmake from the
Visual Studio Command Prompt (vcvarsall.bat).
Tell CMake where to find the compiler by setting either the environment
variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
the compiler, or to the compiler name if it is in the PATH.

cl
是 Microsoft Visual Studio 编译器。默认情况下,IIRC MSYS(和 MSYS2)不会安装 MinGW(这是包的编译器组件)。你安装了MinGW吗?在 MSYS shell 中,如果运行程序会发生什么?你从哪里跑?gcc
cmake
gcc --version
gcc
cl
cl.exe
cmake
cl.exe
g++
gcc
