I am thinking of rebuilding the project from scratch which I would like to avoid, so I am asking for help.
When trying to build the project on release I get the following link error:

No problem with debug mode. The project runs fine on another computer on xcode 4.5.1. I thought the xcode version could be the problem but when I tried it on another computer with xcode 4.5.1 I got the same problem.
The project uses a library libVideoWebiOS. I have it on the Build Phases -> Link Binary With Libraries. Any idea what produce could this issue? Here is the screenshot of build settings -> architectures.

There are lot of suggestions to Change "Build Active Architecure Only" to Yes but unfortunately that didn't work for me.
