installing opencv

edit

Hy,

I need OpenCV for a project I'm working on, however so far I've not been able to successfully build it. I've been trying numorous build guides and haven't found any solution yet. The make process always fails with the errors listed in the code section below.

I found several posts online of people having the same issue. However I've tried all these and none of them seemed to work for me.

I originally was trying to build an older version of opencv 2.4.9 because some of the code I'm using is using the older opencv. However, even with the new version 3.0 it is not working for me. Does anyone have any suggestion what I might try?

I will also include the result of the cmake configuration.

Thanks.
