How to build 32-bit library?

I have a 64-bit system (linux) and want to build a 32-bit QTD for use with dmd2. How do I pass the right flags or set the right options in ccmake so it doesn't want to link with the 64-bit QT libraries? I do have all the 32-bit libraries in place.

Thanks.

We've never tried such a combination of OS/compiler, and I'm afraid the build system cannot account for that. The cmake guy is not around very often lately, but it would be good if you file an appropriate ticket, preferably with some explanation how it can be done(at least library names, etc).

Thank you.

Sorry that it took me so long and for the messy formatting. I was able to build QtD for dmd on 64-bit, here is my ticket:
http://www.dsource.org/projects/qtd/ticket/37

I don't think there are any different libraries required, just a 32-bit package of qt-devel and all it's dependencies. You will notice linker errors when missing a package, it's tedious but trivial to install them by hand if need be.

My solution to build QtD for dmd is by using the -m32 option in the right flags, I kinda forgot that there is also a windows target: would this still be portable?

EDIT: I noticed that minGW is required on windows, so -m32 for sure should be ok there.
