Hello, I am using gcc version 2.8.1 on HP-UX B.11.11. I am trying to compile my ?C? program with 64-bit version library. It gives following error: Not a valid library (invalid magic number). Possibly a 64-bit PA archive library (Mismatched ABI). Is gcc 2.8.1 support 64-bit version? How can I compile with 64-bit version library? I would appreciate any guidance! Thanks, PP __________________________________ Do you Yahoo!? Make Yahoo! your home page http://www.yahoo.com/r/hs
