Hello,
I tried to build opencv 2.4.9 in code::blocks 13.12 on windows 7(32bit). I instaled MinGW - CMake and after this, I tried to build in code::blocks (steps: http://jatb181.blogspot.sk/2014/06/install-opencv-248-with-codeblocks.html or http://zahidhasan.wordpress.com/2013/02/16/how-to-install-opencv-on-windows-7-64bit-using-mingw-64-and-codeblocks/). But I becomed error during build in 33%:
