Qt3.3.8 using 32-bit linux in a 64-bit environment

flopez

Hi, I would like to build from source Qtv3.3.8.

I have a SL Red Hat 64 bit machine, however I want to to install Qt using 32 bit.

How should I run ./configure considering the architecture that I want?

How do I call ../mkspecs/linuxg++-32?

Do I need to edit ../qmake/Makefile.unix (ie do I need to add -m32).

Thanks in advance.

I dont think its possible to only build Qt as a 32 bit, when your whole toolchain is setup for 64 bit.
So you have to make a 32 bit toolchain next to the 64 to get it working.
Im not sure though, but i remember reading about it once.

hi vinb,

I tried ./configure --platform=linux-g++-32 -thread -no-xft -qt-gif -no-exceptions and I have this problem with -lGL.

With --platform=linux-g++-32, it adds the option -m32 at compile time, in principle. However with the problem i cite above it searches for /usr/lib64/libGL.so while I would require that it reads the file in the path /usr/lib/libGL.so.

What more do i need to tweak?
