I just built and installed gcc-3.3.2 on my machine (RedHat Linux 7.0), and used g77 to compile a very simple fortran program. Upon running this program, I get: error while loading shared libraries: libg2c.so.0: cannot load shared object file: No such file or directory. libg2c.so.0 exists alright, in /usr/local/lib, which is in my path. Not sure why a shared object is needed at run-time anyway. Does this indicate that the compiler/assembler has created an executable that is "missing" something? Thanks for any help - Mark Rashid
