Programs compiled 32-bit will run just fine on 64-bit operating systems, so long as you have all the necessary 32-bit libraries. However, 64-bit binaries will not work on 32-bit systems. You can also compile 32-bit applications on 64-bit systems and vice versa, but you need a cross compiler setup which can be a PITA. Personally, I also like to keep as much managed by RPM as possible. So, if I want a custom version of a package provided by Fedora, I just modify it's RPM specfile, and for projects that don't exist I create my own RPMs. When you use RPM, you can build 32-bit and 64-bit versions regardless of the architecture of the system you happen to be using at the time very easily, using mock. Compiling a 32-bit RPM on a 64-bit system is as easy as: % mock -r fedora-16-i386 --rebuild super-cool-app-0.1.fc16.src.rpm For more information on creating your own RPMs, see: http://fedoraproject.org/wiki/How_to_create_an_RPM_package For more information on mock, see: http://fedoraproject.org/wiki/Projects/Mock -T.C. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
