install QT as 32 bit

Hi

Is there a way to force QT to install as 32bit on a machine which supports both 32 and 64 bit? The reason I am asking this is, I am trying to install QT on IBM Cell Processor with Mesa3D gallium OpenGL drivers support. The opengl drivers are installed as 32bit, so the installation process for QT skips those drivers and looks for 64 bit drivers. I believe if I can somehow force QT to install as 32 bit rather than in 64 bit, my problem will be solved.

Thanks

Saad

How are you installing Qt?

Re: install QT as 32 bit

Hey I am configuring it using the following options

./configure -release -prefix /usr/local/Trolltech/qt -fast -no-qt3support -L/home/user/mesa/lib/gallium -opengl desktop -nomake examples -nomake demos -nomake tools

During configure , Qt determines that this is a power pc and adds -m64 flag to all the g++ commands in makefiles. But my opengl drivers are compiled as 32 bit hence while doing gmake (after configure) it skips that particular libGL.so file by expressing that is incompatible.

Thanks for your reply :).

Use the -platform switch with appropriate option (i.e. linux-g++-32) to build Qt for specific architecture.

Re: install QT as 32 bit

Hey that seemed to work :D but when after configure i ran gmake I got this error

"cc1plus: out of memory allocating xxxxx bytes "

so instead of release flag in configure I tried with debug and got this error during gmake.
"

any clues?

Thanks again

PS: Currently hardly any ram is free on this machine and no swap has been defined, maybe that could be causing the memory issue.

You may indeed be having RAM issues.
