Errors while compiling Qt Creator 3.0.0 on CentOS6.4
-
Hi,
I successfully managed to create a Qt 5.2.0 build on my platform, and I am now attempting to create a Qt Creator 3.0.0 build. I keep getting the following errors and have no clue what it means and what I should look for to solve the problem. Any ideas what I did wrong here?

Thank you for your answer. I definitely think this is compiler related. CentOS's gcc is a bit old.
Btw, any idea if this could be C++11 related? I had to compile Qt with --no-c++11 since CentOS does not support C++11 yet, but I couldn't find any similar option for Qt Creator.
