Configure error building Qt 4.4.3 on Red Hat Enterprise Linux 4

I am trying to build Qt 4.4.3 on Red Hat Enterprise Linux AS release 4. When i run configure, i get the following error (I have removed similar errors to make the post readable):

Now, i have the following g++ versions installed:

I think by default Qt is picking up g++ i.e. g++ version 2.95.3. Could this be the source of the problem?

Yes, it could. See Supported Platforms and Compilers (http://trolltech.com/developer/supported-platforms).

i got it working. Qt was picking up gcc 2.95, so i renamed the gcc to gcc295 and renamed gcc344 to gcc.
