I need to get 32 bit qt libs

Question

Is there a quick way to obtain a set of 32 bit qt libraries? I need to put them on my 64 bit ubuntu os which already has qt installed (64 bits).

If you already have the generic source, then run configure with the following option:

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

I got the source for qt but I got the following error: linux-g++-32: unknown argument The specified system/compiler is not supported: /home/yan/qtSource3/mkspecs/yes – yan bellavance Apr 23 '10 at 19:35

`qtSource3` seems to imply that's Qt-3? Is a linux-g++-32 bit folder present in the mkspecs directory? – Kaleb Pederson Apr 23 '10 at 19:58
yes the folder is present and no it is not it is not qt3, I simply called it like that, I had more than one folder of qt source – yan bellavance Apr 23 '10 at 20:37

Do you have the `*-multilb` packages installed for gcc? – Kaleb Pederson Apr 23 '10 at 20:44

sudo apt-get install ia32-libs

According to the content listing at http://packages.ubuntu.com/karmic/ia32-libs it contains 32bit QT.

You'll need to verify that you don't have a higher version of glibc, and then confirm that your version of Qt isn't compiled against something not present on his, such as `XFixes` which isn't present on older systems. Providing binaries is nice, but it's also somewhat of an art form. – Kaleb Pederson Apr 23 '10 at 20:00
You are right, it is alot more complexe than just installing the 32 bit version of qt. I was successfull in providing 64 bit binaries to multiple linux distros that are also 64 bit but now this adds another obstacle to my goal. I will probably just use a vm machine if i dont get this resolved soon. – yan bellavance Apr 23 '10 at 21:05
