forget eclipse for a moment. if you're trying to use mingw, job #1 is to build the opencv libs using that.

and we can't help without seeing your errors !

modules\legacy is not a part of opencv3.1. you must be trying with a previous 2.4.x version

your mingw version is too old , to be useful, too.

try to get mingw64 instead

Hi,

Please go to this link and check the code:

https://github.com/mshabunin/opencv/b...

This is the fix of the parallel.cpp of the OpenCV for Netbeans or eclipse on Windows 64-bit.

I used the MinGW64, CMake and msys to compile the OpenCV by replacing the parallel.cpp with the above mentioned one.

I followed these blogs: 1. http://zdravv.ru/watch/G9IBIEDex18/ho... 2.https://zahidhasan.wordpress.com/2013/02/16/how-to-install-opencv-on-windows-7-64bit-using-mingw-64-and-codeblocks/

You can download code blocks from: http://www.codeblocks.org/downloads/26

I hope this is helpful!

regards.
