OpenCV - Error C2244

I'm currently on vacation far away from my desktop, however I wanted to practice my c++ in particular with openCV, so I brought my laptop along. Given time and family constraints I didn't get everything set up in time with the libraries before flying.

I've set everything up with regards to VS 2010 as I recall doing on my desktop a while ago, but on compiling the test example on the openCV website (http://opencv.willowgarage.com/wiki/VisualC%2B%2B) I receive the following errors:

Error   3   error C2244: 'cv::Matx<_Tp,,>::diag' : unable to match function definition to an existing declaration   C:\Program Files\OpenCV2.2\include\opencv2\core\operations.hpp  372
Error   4   error C2244: 'cv::Matx<_Tp,,>::diag' : unable to match function definition to an existing declaration   C:\Program Files\OpenCV2.2\include\opencv2\core\operations.hpp  448

which in turn shows me:

template<typename _Tp, int m, int n> inline Matx<_Tp,m,n> Matx<_Tp,m,n>::diag(const Matx<_Tp,MIN(m,n),1>& d) { Matx<_Tp,m,n> M; for(int i = 0; i < MIN(m,n); i++) M(i,i) = d[i]; return M; }

template<typename _Tp, int m, int n> inline Matx<_Tp, MIN(m,n), 1> Matx<_Tp, m, n>::diag() const { diag_type d; for( int i = 0; i < MIN(m, n); i++ ) d.val[i] = val[i*n + i]; return d; }

I've looked into this error on the msdn and have looked on the openCV forums, but I couldn't find record of this specific error and I'm not sure how to resolve it.

Is it also problematic that I'm running the 64 bit version of Windows 7? I read that openCV2.2 is compatible however previously while the programs would compile, it kept on saying the .dll files were missing even though the PATH variable and directori开发者_开发知识库es were correct.

Thanks, Jean-Pierre

I had the same issue running Opencv2.2 on 32bit Win7 VS2010 and QT 4.7.2.

I doesn't seem to be an error that affects the actual function of code. When I turned code analysis off as Himanshu jain described above it fixed the problem.

It seems indeed that the option advanced compiler option "/analyze" causes this problem (I'm using OpenCV 2.2 with VS 2008 on Win XP 32bit). I could fix the first error:

In line 365, you got to replace Matx<_Tp,MIN(m,n),1> with diag_type, i.e. this

template<typename _Tp, int m, int n> inline
Matx<_Tp,m,n> Matx<_Tp,m,n>::diag(const Matx<_Tp,MIN(m,n),1>& d)

becomes

template<typename _Tp, int m, int n> inline
Matx<_Tp,m,n> Matx<_Tp,m,n>::diag(const diag_type& d)

Unfortunately, the 2nd error still occurs -- I found no way to get rid of it but to deactivate \analyze :-(

1>D:\OpenCV2.2\include\opencv2/core/operations.hpp(447) : error C2244: 'cv::Matx<_Tp,,>::diag':  
unable to match function definition to an existing declaration

If you find a way to fix this, please let me know -- I think I'll go ahead and post a bug-report-ticket on OpenCV Trac now...
