使用Mingw-w64编译Google测试 [英] Compiling Google test with Mingw-w64

问题描述

我正在尝试在Windows 10计算机中使用Mingw-w64编译Google Test，但始终会收到错误消息:

I'm trying to compile Google Test with Mingw-w64 in a Windows 10 machine but I always get the error:

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!

这就是我在做什么:

1. 打开Windows CMD终端并更改我下载google test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

1. Open a Windows CMD terminal and change folder t where I downloaded google test
2. Add CMake, make and g++ to the path 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. Run CMake with cmake CMakeLists.txt -G "MinGW Makefiles"

这些是工具的版本:

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

使来自此处

非常感谢您的帮助！

CMake/MinGW未知的编译器，gcc.exe损坏，都没有解决方案.

我还尝试使用环境变量来告诉CMake使用哪些工具.

I also tried using environment variables to tell CMake which tools to use.

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%

1. 通过调用CMake

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.

由于g ++和gcc在PATH中，因此我也尝试像这样调用CMake:

As g++ and gcc are in the PATH, I also tried to call CMake like so:

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

产生与上一次尝试相同的错误:

Which yields the same error as the previous try:

-- 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 CAN 拨打g++:

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

再次感谢！

推荐答案

您的原始问题源于对MSYS2使用 make.exe 的选择. 以及该版本的 make.exe 不支持的MinGW-w64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修改，但是例如在 cmd.exe :

Your original problems stem from the choice of using make.exe for MSYS2 together with the MinGW-w64 compiler, which is not supported by that version of make.exe. The correct program to use with MinGW-w64 is mingw32-make.exe, which is part of the MinGW-w64 distribution. I am not fully able to follow your later edits, but for instance this works perfectly well in cmd.exe:

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，我用过

• CMake 3.15.2，
• MinGW-w64 8.1.0(
• CMake 3.15.2,
• MinGW-w64 8.1.0 (x86_64-8.1.0-posix-seh-rt_v6-rev0),
• and current git revision of Google Test.
