我没有问题链接动态opencv库，但我想要使用静态库，所以我重新选择了“生成共享库”选项未选中的OpenCV 2.3。我把我的.pro文件以下需要帮助链接在Windows上的Qt Creator中的静态OpenCV库
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"
这是非常相似，我收到的时候我用的是动态库，除了在.dll文件。一个真正结束了.a文件，我把dll的（不是dll.a文件）在qt程序的输出目录中（所以程序可以找到它们并运行）。现在重点是我不需要这些dll，所以它们不再在我的程序的输出目录中（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遇到这些错误：

我正在使用MinGW。使用用于构建opencv的相同工具链编译该项目。如上所述，使用动态库。不适用于静态库。
只是一个问题：如何做你设法用Qt支持构建opencv？我的构建不成功，因为它需要一个名为'qconfig.h'的文件，这个文件没有伴随我的Qt 4.6.3下载。你使用了哪个版本？ – vsz 2012-04-07 16:22:06
@vsz对于迟到感到抱歉。我没有试图用qt支持构建opencv。我只是将opencv库导入到我正在编写的qt程序中。 – jzepeda 2012-04-18 02:48:28
