Compiling Google test with Mingw-w64

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!

This is is what I'm doing:

  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"

These are the versions of the tools:

GNU Make 3.81

This program built for i686-pc-msys
  • cmake version 3.15.3
  • g++ (i686-posix-dwarf-rev0, Built by MinGW-W64 project) 8.1.0

Make comes from the MSYS package from Mingw-64w. I cloned Google Test from here

Any help is much appreciated!

EDIT 1

None of the solutions in CMake/MinGW unknown compilers, gcc.exe broken work.

EDIT 2

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

  1. Added the tools' folders to the 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. Calling CMake with

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"

I get this error:

-- 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.

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"

Which yields the same error as the previous try:

-- The C compiler identification is unknown
-- The CXX compiler identification is unknown

  The CMAKE_C_COMPILER:

    gcc

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

  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.

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

However, I CAN call g++:

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

Thanks again!

Solution

  • 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

    Here, I used:
