Hello all,

Have installed eclipse 3.5 x86_64 from the eclipse site, with CDT and QT integration.

I am just starting to learn C++ but I would like to know how to set up the ability to compile for 32 bit as well?

specify -m32 as a gcc (or g++ or c++) compile time option, and use the libraries in */lib rather than */lib/64

this has nothing to do with eclipse, eclipse is a Java IDE, this is plain gcc/makefile stuff. It also has nothing to do with CentOS.
