Qt build error

Hi,
I am installing Qt 5.7 in RHEL6.6. I get the following error while run:

Hi @prerna ,
I had just installed qt 5.7 on RHEL6.6 and the installation went perfect,
Probably u have missed some installation steps...

i used offline installer and GCC is 4.4 maybe that is the prob i need GCC 4.7 i think
-
could you please mention the steps you followed and from which file did you install? .run/.tar etc
Also what necessary files should be downloaded for Qt to run without any problems?
-
Hi,
Either use a version of Qt that is smaller that 5.7 or upgrade your compiler.

Hi,
Thank you :)I figured out it was not working first because of gcc compiler (the version i had was an old one) i installed gcc4.8.1after that through devtoolset-2 and it worked fine.However there is new error LibGL error unable to load driver nouveau_dri.so
Can you tell me what is this error?
-
What OpenGL library do you have installed ?
-
i did not install any. How to do that? which one should i install

Since you're on RedHat:
yum install mesa-libGL-devel
