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?

Edit: Here are configure options

It's normal with the default CMake on CentOS 6.5

$ cmake --version cmake version 2.6-patch 4

if you look the documentation[1] of CMake you will not see the function : string(< MD5|SHA1|SHA224|SHA256|SHA384|SHA512> < output variable> < input>)

one solution is to comment the line (what I did) or upgrade cmake to a newest version [2].

I tried it on CentOS6 64 bit with cmake-2.8.5-3 and works fine without any error. What is your version ?

I added my cmake output in the first post so you can see all my version related information.

Got the same error when I built it (opencv-2.4.7 on CentOS 6.4) with cmake (2.6?) which I installed via yum. Passed without errors when I built it using the latest cmake (2.8.12) I installed from source.
