QMAKESPEC setting problem while compiling on AMD 64 bit m/c

[a_m_mukul]

Hi,

I have created one 32 bit application with Qt4.2.2.
When I am trying to compile the same application on
AMD 64 bit m/c RedHat Enterprize -3 paltform. I am getting following error

"QMAKESPEC has not been set, so configuration cannot be deduced."

I tried to set it with followings:
QMAKESPEC=qt4.2.2-static/mkspecs/linux-g++-64
QMAKESPEC=qt4.2.2-static/mkspecs/linux-g++-32

Then I am getting a lot of errors in my code.

Please can anybody tell me to what to set it.

My Qt is installed on Fedora core -5 platform, and I am accessing
that through LAN seeting.

Try "QMAKESPEC=linux-g++-32" or "QMAKESPEC=linux-g++-64".
