Need 32 bit libusb on 64 bit system

view full story

http://forums.fedoraforum.org – I'm running Fedora 11 on a 64 bit HP Pavillion. I installed a program (vuescan) but when I try to run it, I get error while loading shared libraries: libusb-0.1.so.4: cannot open shared object file: No such file or directory That presumably is because it can't find that library in /usr/lib. (It is of course in /usr/lib64.) There doesn't seem to be any standard compatibility package in my yum sources. I downloaded an rpm package for the 32 bit version, but rpm won't install it because it says it is already installed. I could of course force an install, but I am a bit nervous about that since I may have problems keeping everything up to date with yum in the future. Also, presumably this is not the only shared library I need for the program to run. Are there additional downward compatible libraries I can find to deal with such problems? (The only standard one seems to be for libstdc++.) Any other suggestions? (HowTos)
