Question

我想在opencv中使用QT，因此我必须使用mingw进行编译。当我想用CMake 2.8.10.2编译它时，它有以下错误

The CXX compiler identification is GNU 4.7.2

Check for working CXX compiler: C:/Qt/Qt5.0.1/Tools/MinGW/bin/g++.exe

CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeTestCXXCompiler.cmake:54 (message):
      The C++ compiler "C:/Qt/Qt5.0.1/Tools/MinGW/bin/g++.exe" is not able to
      compile a simple test program.

      It fails with the following output:

      CMake will not be able to correctly generate this project.
    Call Stack (most recent call first):
      CMakeLists.txt:61 (project)


    Configuring incomplete, errors occurred!

任何想法？

我有一个较新的版本但在我的情况下你应该尝试在文件夹QtSDK / minGW / bin而不是Qt文件夹。
