我沒有問題鏈接動態opencv庫，但我想要使用靜態庫，所以我重新選擇了「生成共享庫」選項未選中的OpenCV 2.3。我把我的.pro文件以下需要幫助鏈接在Windows上的Qt Creator中的靜態OpenCV庫
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_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"
這是非常相似，我收到的時候我用的是動態庫，除了在.dll文件。一個真正結束了.a文件，我把dll的（不是dll.a文件）在qt程序的輸出目錄中（所以程序可以找到它們並運行）。現在重點是我不需要這些dll，所以它們不再在我的程序的輸出目錄中（實際上它們不是用OpenCV構建的）。但是當我嘗試構建我的程序時遇到這些錯誤：

我正在使用MinGW。使用用於構建opencv的相同工具鏈編譯該項目。如上所述，使用動態庫。不適用於靜態庫。
只是一個問題：如何做你設法用Qt支持構建opencv？我的構建不成功，因爲它需要一個名爲'qconfig.h'的文件，這個文件沒有伴隨我的Qt 4.6.3下載。你使用了哪個版本？ – vsz 2012-04-07 16:22:06
@vsz對於遲到感到抱歉。我沒有試圖用qt支持構建opencv。我只是將opencv庫導入到我正在編寫的qt程序中。 – jzepeda 2012-04-18 02:48:28
