【问题描述】：
链接动态opencv库没有问题，但我想改用静态库，所以我重建了OpenCV 2.3，未选中“构建共享库”选项。我将以下内容放在我的 .pro 文件中
LIBS += "C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_calib3d231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_contrib231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_core231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_features2d231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_flann231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_gpu231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_highgui231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_imgproc231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_legacy231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_ml231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_objdetect231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_ts231.a" \
"C:\Program Files\openCV_static\opencv\build\install\lib\libopencv_video231.a"
INCLUDEPATH += "C:\Program Files\openCV_static\opencv\build\install\include"
INCLUDEPATH += "C:\Program Files\openCV_static\opencv\build\install\include\opencv"
这与我之前使用动态库时的情况非常相似，除了 .a 文件实际上以 .dll .a 结尾，并且我将 dll（不是 dll.a 文件）放在 qt 程序的输出目录（因此程序可以找到它们并运行）。现在重点是我不需要那些 dll，所以它们不再在我程序的输出目录中（实际上它们不是用 OpenCV 构建的）。但是当我尝试构建我的程序时出现这些错误：

我正在使用 MinGW。使用用于构建 opencv 的相同工具链编译项目。如上所述，使用动态库。不适用于静态库。
【问题讨论】：

只是一个问题：您是如何设法构建带有 Qt 支持的 opencv 的？我的构建没有成功，因为它需要一个名为
qconfig.h的文件，而我的 Qt 源 4.6.3 下载没有附带该文件。你用的是哪个版本的？ -
@vsz 抱歉迟到了。我没有尝试构建带有 qt 支持的 opencv。我只是将 opencv 库导入到我正在编写的 qt 程序中。
