Fortran call_external under linux



Dear all,

We are currently migrating from SGI IRIX to Red Hat 6.2 Linux. We rely on
some fortran code, and would prefer to be able to use call_external instead
of spawn with all its overhead etc.

Apparently IDL does not have any example fortran code to work with the g77
compiler, and the IRIX code does not compile. It seems that the 
"structure" and "record" constructs which is used to pass 
strings between IDL and fortran is not recognized by g77.

Does anybody have experience with compiling fortran under Linux and linking
it to IDL (5.4) ?

Greetings, Ole BC, Danish Met. Institute
