Codeblock+opencv+windows - strange errors

[Berial]

Hi
I have problem with linking opencv and codeblocks on Windows Vista. On linux everytghing works great, however I would also like to have working opencv library on Windows. So I added

Code

-lcxcore -lcv -lcvaux -lhighgui -lml -lcvcam

to linker options, furthermore I added

Code

C:\OpenCV2.0\src
C:\OpenCV2.0\include\opencv
C:\OpenCV2.0\lib

to search directories. Unfortunatelly I can't compile any program now, even programs without any of opencv functions.
I got error

Code

ld.exe||cannot find -lcxcore|
||=== Build finished: 1 errors, 0 warnings ===|

When I add

Code

#include <cv.h>

to main.cpp file I got a lot of errors

Code

So could sb tell me what did I do wrong? I didn't have problem with linking this library on linux, however on windows it is terrible experience.
PS
I use codeblocks 8.02 and OpenCV 2.0a

[ollydbg]

If I remember correctly, opencv 2.0 library is build in TDM-GCC 4.xxx. And the compiler bundled with Codeblocks8.02 is using an old GCC.

I suggest you should use a more recent Codeblocks version, such as a  nightly build version.

Also, a more recent GCC compiler, such as TDM GCC.

[DavidM]

In  OpenCV2.0\include\opencv\cxoperations.hpp
change line 68 from

Code

        #if __GNUC__ >= 4

To

Code

        #if __GNUC__ >= 4 || __MINGW32__

[Vuki]

Code

-lcxcore -lcv -lcvaux -lhighgui -lml -lcvcam

Code

ld.exe||cannot find -lcxcore|
||=== Build finished: 1 errors, 0 warnings ===|

Check filenames in C:\OpenCV2.0\lib. If you use pre-built version for Windows, there is no libcxcore.a file there, the file is named libcxcore200.dll.a. Therefore, you need to use -lcxcore200.dll instead. The same rule applies to other libraries (-lcv200.dll and so on).

As for compiler errors, I think you use old compiler version (3.x). Updating to gcc 4 should make it work.
