1.提示进程"C:\Qt\QtCreator\bin\jom.exe"崩溃。

工具 ->选项->构建和运行-> 概要将使用jom代替nmake取消勾选

2 配置QT OPENCVE

http://www.linuxidc.com/Linux/2013-04/83231.htm

在每个Qt工程的 .pro文件中添加头文件和lib文件。（注：每新建一个工程都需要修改，很麻烦）
参考如下：（代码在.pro中位置随意，最前面或最后面都可以；安装路径不同的，只要改一下自己的正确安装路径即可）

INCLUDEPATH += C:\OpenCV2.4.4\opencv\build\include\opencv2\
              C:\OpenCV2.4.4\opencv\build\include\opencv\
              C:\OpenCV2.4.4\opencv\build\include

CONFIG(debug,debug|release)
{
LIBS += C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_calib3d244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_contrib244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_core244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_features2d244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_flann244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_gpu244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_highgui244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_imgproc244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_legacy244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_ml244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_objdetect244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_ts244.lib\
        C:\OpenCV2.4.4\opencv\build\x86\vc10\lib\opencv_video244.lib\
}

根据所安装版本的OPENCV进行适当修改。

3 OpenCV Error: Bad flag (parameter or structure field)

Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

网上一直没有找到解决方法，后来发现把项目构建由debug改为release就没有这个问题了。
