Hi, I just installed RH9 for the 1st time, then I installed the new java 1.4.2 rpm. all went smoothly. When trying to run a GUI java program got error message. something like: missing file "libstdc++-libc6.1-1.so.2". I then installed MANY packages from the RH9 3 CDs, till the file was created and the program agree to run. My questions are two: 1) Which sole package is needed in order to have this file? 2) in general, how to determine which package is needed for a particular file or software. thanks, Avner
