Dear SL-5.1 users, I'm trying to install an application on CentsOS-5.2. The application works well on ScientificLinux-5.1but its failing to run on CentsOS-5.2(compilation goes smooth). That's because CentOS is lacking some of the rpms compared to SL-5.1. As the program fails by just showing <library name>.so not found error, I'm not able to find from which rpm that library come from. Following is the list of missing libraries: libGeoBase.so libParBase.so libBase.so libCbmBase.so libCbmData.so libField.so libGen.so libPassive.so libSts.so libTrd.so libTof.so libMuch.so As I don't have SL-5.1, I request any one of you to check which rpm these library belong to, i.e. the following 2 commands $ locate libGeoBase It will give the path of libGeoBase $ rpm -qf <path of libGeoBase> It will give the name of rpm. Same steps should be carried for other libraries also. Send me the list of rpms. Thanks for your kind help
