Error compiling 32-bit Qt-4.7 on 64-bit Ubuntu OS

Hi,

I am compiling Qt-4.7 for 32-bit on 64-bit (x86_64) Ubuntu 8.04 desktop. I have installed all the 32-bit libraries (/lib32 and /usr/lib32) through getlibs and "apt-get install ia32-libs". But I am getting the following error while configuring the qt project as:

./configure -platform linux-g++-32

Error: /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.2.4/libstdc++.so when searching for -lstdc++

It seems, the compiler still searching the libstdc++ in the 64 bit lib path inspite of the configuration argument for 32-bit.

Please let me know how to overcome this error

If you can append -m32 to CFLAGS that might help.

Thanks corono for your reply. But it did not solve my problem.

But the problem got solved by installing the following:

sudo apt-get install g++-multilib
