Windows上的mingw32-make时opencv安装错误 [英] opencv installation error while mingw32-make on windows

问题描述

在Windows 10平台中使用mingw32-make命令进行opencv安装，然后可能最终得到以下错误.

opencv installation using mingw32-make command in windows 10 platform, then likely end up in getting the below error.

Windows版本:10 OpenCv:3.2.0

Windows version : 10 OpenCv:3.2.0

请建议我安装.

推荐答案

在尝试使用 mingw32 在上构建 OpenCV 3.2.0 时，我也遇到了相同的问题. > Windows10 .我进行了一些搜索以找到对Github的修复，以解决类似问题.它说问题是:

I also faced the same problem while trying to build OpenCV 3.2.0 using mingw32 on Windows10. I searched a bit to find a fix on Github for similar problem. It said the problem was:

MinGW将_CRITICAL_SECTION和_RTL_CRITICAL_SECTION定义为两个单独的(等效)结构，而不是使用typedef

MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two separate (equivalent) structs, instead of using typedef

因此，您必须为_CRITICAL_SECTION和_RTL_CRITICAL_SECTION添加另一个typedef GTEST_CRITICAL_SECTION，并在两种情况下都使用此typedef.

So, you have to add another typedef GTEST_CRITICAL_SECTION for _CRITICAL_SECTION and _RTL_CRITICAL_SECTION and use this typedef for either case.

这是要执行的操作:

编辑"ts_gtest.h" ，该文件位于"opencv \ sources \ modules \ ts \ include \ opencv2 \ ts \"

1. 替换此行(可能是723行)
   

    // 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;

使用

    #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

1. 替换此行(可能在您进行编辑之前在第3060行-修改第一部分时行号将发生更改)

    _RTL_CRITICAL_SECTION* critical_section_;

使用

    GTEST_CRITICAL_SECTION* critical_section_;

这两个更改应该可以解决您的上述错误.

These two changes should fix your above error.
