After doing the " rpmbuild --rebuild dosemu-1.4.0-1.src.rpm" step that errored out as described in my previous message, I had a file named dosemu-1.4.0.tgz in my ~/rpmbuild/SOURCES directory. I un-tarred that and after poking around a bit I found a file named compiletime-settings. I changed the line in that file that said libdir ${prefix}/lib to libdir ${prefix}/lib64 I then recreated dosemu-1.4.0.tgz in the ~/rpmbuild/SOURCES directory so it now contained the modified compiletime-settings file. After that, doing a "rpm -bb ~/rpmbuild/SPECS/dosemu.spec" created the file that I wanted, dosemu-1.4.0-1.x86_64.rpm. I installed it and it appears to work as expected. PERFORMANCE This 64-bit DOSEMU compile runs substantially slower than the 32-bit compile that I used previously on this computer. I have several rather large PowerBASIC/DOS programs that are, in fact, the main reason why I use DOSEMU. Up until a couple of days ago, I had Fedora 7/i386 on this computer. I just happen to still have the numbers when compiling one of those programs with PowerBASIC/DOS under DOSEMU: With F7/i386: 1686600 lines per minute -- total time to compile the program: 0.2 seconds With F8/x86_64: 230400 lines per minute -- total time to compile the program: 1.6 seconds. The F8/x86_64 DOSEMU is running approximately 13 times slower. I understand that DOSEMU has to do more work to run on a x86_64 architecture. However, I'm wondering if there is something that I missed or something that I should do (compiler options?) that would give it a bit more oomph. -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
