2013-11-21 07:47:43 -0600	commented answer	Building opencv-2.4.6.1 or 2.4.7 on CentOS 5 I can't accept this answer because I'm new, but this is what I would accept...
2013-11-21 07:46:36 -0600	answered a question	Building opencv-2.4.6.1 or 2.4.7 on CentOS 5 I was able to fix this by using gdkglext and gdkglext-devel 1.2.0-4 which I found for CentOS 5 from here
2013-11-20 07:58:09 -0600	commented answer	Building opencv-2.4.7 on CentOS 6 I added my cmake output in the first post so you can see all my version related information.
2013-11-18 15:56:30 -0600	asked a question	Building opencv-2.4.7 on CentOS 6 I was able to build opencv-2.4.7 on CentOS 6 but I had to edit /usr/local/src/opencv-2.4.7/cmake/cl2cpp.cmake and comment out string(MD5 hash "${lines}") on line 50. Otherwise I would get this error: `string does not recognize sub-command MD5` Are there any negative consequences from commenting out that line?
