Clint,

I looked at our WS 7.0 lib directory. There is a libf77compat
that appears to contain symbols necessary to link f77 compiled libraries
with your f90/f95 program. Try adding -lf77compat to your link line.

>Chiz,
>I want to rewrite a F77 program in F90 to convert some MM5 output to
>gempak format.  The program works fine now but when I try to compile
>it with the f90 compiler instead of the f77 compiler, it cannot resolve 
>references in gemlib.  I'm assuming this is because the standard libraries

>references are to libraries that would be searched when using the f77 
>compiler but not the f90 compiler.  So, my question(s) is/are:

>1) can I just specify some f77-specific libraries to be searched when

>   libraries do I need to specify?
>   
>2) do I need to compile gempak using the f90 compiler and, if so, has

>3) is there another course of action I could take or should I just abandon
