在 QT Creator 中构建 OpenCV 应用程序
我在 Visual studio 10 下使用 CMake 构建了 OpenCV，将二进制文件复制到 opencv 目录中的 /bin 文件夹中。我有一个简单的 OpenCV 程序，没有语法错误，但我收到了几个错误，例如“对 cv::imread 的未定义引用”。这是为什么呢？
我的 .pro 文件末尾附加了以下内容：
INCLUDEPATH += C:/opencv/build/include/
LIBS += -LC:/opencv/build/x64/vc10/lib \
-lopencv_core231 \
-lopencv_highgui231 \
-lopencv_imgproc231 \
-lopencv_features2d231 \
-lopencv_calib3d231
谢谢
I built OpenCV with CMake under Visual studio 10, copied the binaries to a /bin folder in the opencv directory. I have a simple OpenCV program with no syntax errors, but I am getting several errors such as "undefined reference to cv::imread". Why is this?
My .pro file has the following appended at the end of it:
INCLUDEPATH += C:/opencv/build/include/
LIBS += -LC:/opencv/build/x64/vc10/lib \
-lopencv_core231 \
-lopencv_highgui231 \
-lopencv_imgproc231 \
-lopencv_features2d231 \
-lopencv_calib3d231
Thanks

未定义的引用而不是未解析的外部符号意味着您的应用程序可能使用MinGW，并且您不能将gcc与VC++编译的C++一起使用图书馆。undefined referenceinstead ofunresolved external symbolmeans you are probably using MinGW for your application, and you can't use gcc with a VC++ compiled C++ library.
