cmake problems in Windows

问题:

I am trying to compile this (quite complex) piece of code with cmake and MinGW in Windows:

#include <iostream>

int main()
{
    std::cout << "Test" << std::endl;
    return 0;
}

This is the CMakeLists.txt file (which works correctly in Linux):

cmake_minimum_required(VERSION 2.6)

SET(CMAKE_C_COMPILER path/to/gcc)
SET(CMAKE_CXX_COMPILER path/to/g++)

project(cmake_test)

add_executable(a.exe test.cpp)

With the command:

cmake -G"MinGW Makefiles" .

I get these errors:

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeMinGWFindMake.cmake:20 (MESSAGE):
  sh.exe was found in your PATH, here:

  C:/MinGW/msys/1.0/bin/sh.exe

  For MinGW make to work correctly sh.exe must NOT be in your path.

  Run cmake from a shell that does not have sh.exe in your PATH.

  If you want to use a UNIX shell, then use MSYS Makefiles.

  CMakeLists.txt:8 (project)


CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_C_COMPILER_ENV_VAR
CMake Error: Could not find cmake module file:C:/cmake_test/CMakeFiles/CMakeCCompiler.cmake
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:
CMAKE_CXX_COMPILER_ENV_VAR
CMake Error: Could not find cmake module file:C:/cmake_test/CMakeFiles/CMakeCXXCompiler.cmake
-- Configuring incomplete, errors occurred!

These errors did not help me much. Considering it works in Linux, it must be something related to the Window's configuration.

Thank you for any help!

Configuration:
- Windows 7
- MinGW/GCC 4.6.1

回答1:

This is due to you have in your path C:/MinGW/msys/1.0/bin/, for generating projects with CMake and MinGW, delete it from your path and add C:/MinGW/bin/ instead

回答2:

You may have better results with -G "MSYS Makefiles" instead of "MinGW Makefiles" - but I warn you - it is going to be slow.

回答3:

Removing sh.exe from the PATH improved thing.
I get more errors, but at a later stage...
