使用 Mingw-w64 编译谷歌测试

Question

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

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!

这就是我正在做的事情：

1. 打开 Windows CMD 终端并更改我下载谷歌测试的文件夹 t
2. 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%
3. 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Mingw-64w 的 MSYS package 。 我从这里克隆了谷歌测试

任何帮助深表感谢！

CMake/MinGW 未知编译器、gcc.exe中的所有解决方案都无法正常工作。

我还尝试使用环境变量来告诉 CMake 使用哪些工具。

1. 将工具的文件夹添加到 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%

2. 调用 CMake 与

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:

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

  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
  to the compiler, or to the compiler name if it is in the PATH.

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

由于 g++ 和 gcc 在 PATH 中，我还尝试像这样调用 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.


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

    g++

  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 "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
  to the compiler, or to the compiler name if it is in the PATH.


-- Configuring incomplete, errors occurred!
See also "C:/git/tdd/googletest/CMakeFiles/CMakeOutput.log".
See also "C:/git/tdd/googletest/CMakeFiles/CMakeError.log".

但是，我g++ ：

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

再次感谢！

您最初的问题源于选择将make.exe用于 MSYS2 以及 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。 我不能完全遵循您以后的编辑，但例如这在cmd.exe中效果很好：

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

在这里，我使用了：

• CMake 3.15.2,
• MinGW-w64 8.1.0 ( x86_64-8.1.0-posix-seh-rt_v6-rev0 ),
• 和 Google 测试的当前 git 修订版。

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

1. 将路径设置为：

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

2. 调用 CMake 与

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

3. 构建

mingw32-make.exe -j8

我要在这里的肢体上使用 go 并说这可能应该与 Git Bash Z2591C4198B701419FE26E 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。
