I have Red Hat Enterprise Linux AS which has come preinstalled with Qt 3.3.
I downloaded Qt 4.3.3 eval version from the Trolltech site and built and configured it. But when I tried to compile a program it showed up errors from which I figured out that the program was getting compiled with the older preinstalled version. I changed the QTDIR path and the bash profile but in vain. Does this mean that I need to uninstall the older version before installing the newer version?
