Very Computer

I am trying to compile the tcsh under SCO unix.
After several hours effort, I made some progress.
But I always got the following error message when the *.o files were
finally being linked:

-----------------------------------------------------------------
        underfined               first referenced
         symbol                      in file
        crypt                        tc.func.o
        ld fatal: Symbol referencing errors. No output written to tcsh
-------------------------------------------------------------------

I am asking  advice ( I really want to add a tcsh to my SCO because the
csh in SCO lacks some convenient functions)

Thanks in advance
