Thanks. > > --Shuwei The CERNLIB libraries such as libpacklib.a, libkernlib.a,etc have been compiled under HP-UX without specifying the compiler option +z or +Z (position independent code). As a result, one cannot link CERNLIB routines on HP-UX in a shared lib. We are receiving many complaints on this topic. Shared libs are interesting (essential) in the development stage. I can only suggest that enough users send a complaint(suggestion!) to the current CERNLIB team to get: - the archive libraries compiled by default with the option +Z. - better have shared versions of the libraries. We all know that the CERNLIB development/maintenance is now at a very minimal level, but this is an important issue for HP-UX users. The amount of work to implement the option 1 should not be more than a few seconds. Fortran routines can however be linked in your main program.
