我正在尝试使用MinGW Makefiles作为生成器来构建OpenCV。在编译器正常工作的阶段，它失败并显示以下输出：

这是我如何调用CMake来配置我的项目：

cmake -G"$generator" `
      -DCMAKE_BUILD_TYPE="$uconfig" `
      -DCMAKE_C_COMPILER="$c_comp" `
      -DCMAKE_C_FLAGS="$flags" `
      -DCMAKE_CXX_COMPILER="$cxx_comp" `
      -DCMAKE_CXX_FLAGS="$flags" `
      -DWITH_GSTREAMER=TRUE `
      -DENABLE_PRECOMPILED_HEADERS=OFF `
      -DBUILD_TESTS=OFF `
      -DBUILD_PERF_TESTS=OFF `
      -DOPENCV_EXTRA_MODULES_PATH=../cv_contrib_latest/modules `
      ../cv_latest

其中uconfig=RELEASE，generator=MinGW Makefiles，arch=32 flags=m32和cxx_comp=mingw-w64/bin directory。它讨论在链接库时跳过不兼容的内容。这是x86-x64问题吗？据我所知，mingw-w64会同时编译它们，而我正在传递-m32标志来编译x86。

编辑：在同一bin目录中使用x86_64-w64-mingw32-g++.exe进行编译会产生相同的错误。

编辑2：当我删除-m32选项时，错误似乎消失了，因此确实是x86-x64的错误。但是，我尝试链接的库位于目录MINGW_PATH/mingw4/x86_64-w64-mingw32/lib下，因此我假设这些库将是32位版本的库。在网上搜索时，我下载了mingw-w64的网站说它同时支持x86和x64。如何使用mingw-w64为x86进行编译？

确实，mingw-w64编译器是单个目标。您需要从SourceForge下载另一分发，而不是默认分发。我下载并设置了i686-8.1.0-release-win32-sjlj-rt_v6-rev0作为我的工具链，现在可以针对x86进行编译。
