what is this error?

It means that at the specified line in the specified source file, an assignment is done of an errno_t value to a char*, and the compiler doesn't know how to do that (it's not a valid conversion).

So how am i suppose to solve it? hmmm... when i click on the error, it open another files which is not created by me. File name: CVVIDSURV.hpp

>> when i click on the error, it open another files which is not created by me. File name: CVVIDSURV.hpp

That's what the error message indicated :

>> 1>c:\program files\opencv\cvaux\include\cvvidsurv.hpp(285)

The error was detected in file cvvidsurv.hpp at line 285.

Line 285 is this :

>>                 FN = strcat_s(tmp,N);

strcat_s returns an errno_t :

        http://msdn.microsoft.com/en-us/library/d45bbxx4%28VS.80%29.aspx

but FN is defined as a char* :

>>         char*   FN = NULL;


It seems that a normal strcat call has been replaced by a strcat_s call without making up for the differences in how they are called.
Or, the code was written for a different platform.

Where did you get that code ?

Sorry.. By right it was strcat call in the first place. Because before this error( FN = strcat_s(tmp,N);
), it shows this error(strcat) have to use _s so therefore i changed it.

>> it shows this error(strcat) have to use _s so therefore i changed it.

That wasn't an error. It was a warning put in by MS Visual C++ to promote its own non-standard functions.

You can safely ignore the warning :)

oh i see... but it seems like i still cannot get through it.

i having this error.


1>optical flow.obj : error LNK2019: unresolved external symbol _cvCreateGaussianBGModel referenced in function _main
1>C:\Documents and Settings\Others\My Documents\Visual Studio 2008\Projects\optical flow\Debug\optical flow.exe : fatal error LNK1120: 1 unresolved externals

Anyway i got to go soon.. Can you tell me all possible ans and ways then, later in the morning i will try it out again. Thanks.

>> 1>optical flow.obj : error LNK2019: unresolved external symbol _cvCreateGaussianBGModel referenced in function _main

That is because you haven't linked in the library that contains that specific symbol.


>> Can you tell me all possible ans and ways then, later in the morning i will try it out again.

That's fine. But if your original question has been answered, then you should probably close this question.

If you then have further problems, you can open new question(s) for those.

hmm.. i think my original question is linked to this. So you mean which library files i have link yet?

The original question was about what the cause of the C2440 error was. That was answered, and you should no longer have that error.

What you have now is a completely different error, and is due to not linking to the library (add the library file in the linker settings of your project).

oh ok. Thanks. Hopefully you can help me again.

Hopefully you can help me again! Thanks for your help!

The reason we like questions to stay on topic, is to ensure the quality of the PAQ database. If someone looks for an answer to a certain question, we want them to easily find it. Splitting up different questions is one way to ensure that :)

i see. ok thanks for the remainder. Can help me solve other question?

I see that another expert is already helping you, so unless that doesn't lead to anything, I'll hold off for now. But I am monitoring it :)
