Opencv installation error while mingw32-make on windows

Question

opencv using the mingw32-make command on the Windows 10 platform, and then it will probably end up with the error below.

Windows Version: 10 OpenCV: 3.2.0

Please suggest me install.

Answer 1

I also encountered the same problem when trying to create OpenCV 3.2.0 using mingw32 on Windows10 . I searched a bit to find a fix on Github for a similar problem. He said the problem was:

MinGW _CRITICAL_SECTION _RTL_CRITICAL_SECTION () , typedef

, typedef GTEST_CRITICAL_SECTION _CRITICAL_SECTION _RTL_CRITICAL_SECTION typedef .

:

"ts_gtest.h" , "opencv\sources\modules\ts\include\opencv2\ts \"

• (, 723)
  

    // assuming CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
    // This assumption is verified by
    // WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION.
    struct _RTL_CRITICAL_SECTION;

    #if GTEST_OS_WINDOWS_MINGW
        // MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two
        // separate (equivalent) structs, instead of using typedef
        typedef struct _CRITICAL_SECTION GTEST_CRITICAL_SECTION;
    #else
        // Assume CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
        // This assumption is verified by
        // WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION
        typedef struct _RTL_CRITICAL_SECTION GTEST_CRITICAL_SECTION;
    #endif

    _RTL_CRITICAL_SECTION* critical_section_;

    GTEST_CRITICAL_SECTION* critical_section_;
