【问题描述】：

我正在尝试在 Windows 10 机器上使用 Mingw-w64 编译 Google 测试，但我总是收到错误：

C:\git\tdd\googletest>cmake CMakeLists.txt -G "MinGW Makefiles"
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles".  CMAKE_MAKE_PROGRAM is not set.  You probably need to select a different build tool.
CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!

这就是我正在做的：

打开一个 Windows CMD 终端并更改我下载 google test 的文件夹 t 将 CMake、make 和 g++ 添加到路径 set PATH="C:\Program Files\CMake\bin";"C:\msys\bin";"C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin";%PATH% 使用cmake CMakeLists.txt -G "MinGW Makefiles" 运行 CMake

这些是工具的版本：

GNU Make 3.81

This program built for i686-pc-msys

cmake 版本 3.15.3 g++ (i686-posix-dwarf-rev0, 由 MinGW-W64 项目构建) 8.1.0

Make 来自MSYS package from Mingw-64w。我从 here 克隆了 Google 测试

非常感谢任何帮助！

编辑 1

CMake/MinGW unknown compilers, gcc.exe broken 中的解决方案均无效。

编辑 2

我还尝试使用环境变量来告诉 CMake 使用哪些工具。

将工具文件夹添加到 PATH：

set PATH="C:\Program Files\CMake\bin";"C:\Program Files (x86)\mingw-w64\i686-8.1.0-posix-dwarf-rt_v6-rev0\mingw32\bin";%PATH%

使用 CMake 调用

cmake -DCMAKE_C_COMPILER="C:/Program Files (x86)/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin/gcc" -DCMAKE_CXX_COMPILER="C:/Program Files (x86)/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin/g++" -DCMAKE_MAKE_PROGRAM="C:/Program Files (x86)/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin/mingw32-make.exe" CMakeLists.txt -G "MinGW Makefiles"

我收到此错误：

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:10 (project):
  The CMAKE_C_COMPILER:

    C:/Program Files (x86)/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin/gcc

  is not a full path to an existing compiler tool.

  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.


CMake Error at CMakeLists.txt:10 (project):
  The CMAKE_CXX_COMPILER:

  is not a full path to an existing compiler tool.

  Tell CMake where to find the compiler by setting either the environment
  variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path

See also "C:/git/tdd/googletest/CMakeFiles/CMakeError.log".

由于 g++ 和 gcc 在 PATH 中，我也尝试像这样调用 CMake：

cmake -DCMAKE_C_COMPILER="gcc" -DCMAKE_CXX_COMPILER="g++" -DCMAKE_MAKE_PROGRAM="mingw32-make.exe" CMakeLists.txt -G "MinGW Makefiles"

这会产生与上一次尝试相同的错误：

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown
CMake Error at CMakeLists.txt:10 (project):
  The CMAKE_C_COMPILER:

    gcc

  is not a full path and was not found in the PATH.

  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.

  The CMAKE_CXX_COMPILER:

    g++

-- Configuring incomplete, errors occurred!

See also "C:/git/tdd/googletest/CMakeFiles/CMakeError.log".

但是，我可以致电g++：

C:\git\tdd\googletest>g++
g++: fatal error: no input files
compilation terminated.

再次感谢！

【参考方案1】：

您最初的问题源于选择为 MSYS2 使用 make.exe 连同 MinGW-w64 编译器，该版本的 make.exe 不支持该编译器。与 MinGW-w64 一起使用的正确程序是 mingw32-make.exe，它是 MinGW-w64 发行版的一部分。我不能完全理解您以后的编辑，但例如这在 cmd.exe 中运行良好：

set "PATH=C:\Program Files\CMake\bin;%PATH%"
set "PATH=C:\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\bin;%PATH%"

cmake ^
    -G "MinGW Makefiles" ^
    -D CMAKE_C_COMPILER=gcc.exe ^
    -D CMAKE_CXX_COMPILER=g++.exe ^
    -D CMAKE_MAKE_PROGRAM=mingw32-make.exe ^
    .

mingw32-make.exe

这里，我用过：

CMake 3.15.2， MinGW-w64 8.1.0 (x86_64-8.1.0-posix-seh-rt_v6-rev0), 以及 Google Test 的当前 git 版本。

【参考方案2】：

好的，我设法使用 CMDER 的 Bash 控制台对其进行了编译。假设您在 C:\mingw-w64\ 安装了 Mingw-w64（路径中没有空格），这些步骤将为您提供一个在 Mingw-w64 下工作的 Google 测试库

将 PATH 设置为：

PATH=/c/Program\ Files/CMake/bin:/c/mingw-w64/i686-8.1.0-posix-dwarf-rt_v6-rev0/mingw32/bin:$PATH

使用 CMake 调用

cmake -DCMAKE_C_COMPILER=gcc -DCMAKE_CXX_COMPILER=g++ -DCMAKE_MAKE_PROGRAM=mingw32-make.exe CMakeLists.txt -G 'MSYS Makefiles'

使用构建

mingw32-make.exe -j8

我会在这里勉强说这可能应该与 Git Bash shell 一起使用。我仍然没有使用常规 Windows CMD 终端构建它的解决方案。
