配置QT





注意在Qt版本那个地方可以通过QT开发包的的../Qt5.7.0/5.7/clang_64/bin/qmake获得。

配置OpenCV

在新建的QT工程中的.pro文件中添加如下配置代码

INCLUDEPATH += /usr/local/include
INCLUDEPATH += /usr/local/include/opencv
INCLUDEPATH += /usr/local/include/opencv2
LIBS += -L/usr/local/lib \
-lopencv_core \
-lopencv_highgui \
-lopencv_imgproc \

完成以上步骤后按理应该是能成功的，但是运行时发现会出现如下的错误。

dyld: Symbol not found: __cg_jpeg_resync_to_restart
Referenced from: /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO
Expected in: /usr/local/lib/libjpeg.8.dylib
in /System/Library/Frameworks/ImageIO.framework/Versions/A/ImageIO

针对以上问题还需要最后修改下配置，如下图
