The subject says it all. Has anybody successfully used LINKIMAGE
with a runtime license? I have no problems to link external
routines with the full version of IDL.
If I start the respective program with the runtime version of
IDL (version 4.0.1 BTW), it complains that the routines are not
available so I guess LINKIMAGE does not what it's supposed to do.
I suspect that it has to do with the different calling procedures
for full version and runtime version.
In the full version, I start my program with
"idl startscript"
where startscript contains the IDL commands to start the
precompiled program:
linkimage, ...
restore,"program.sav"
start_prog
For the runtime version, this is not possible. In that case you have
to include a "main" procedure in the program save file, which is used
by the runtime version to start the program (idl -rt="program.sav"):
PRO main
linkimage, ...
start_prog
END
The natural way to access the external routines in this case
is to include the linkimage calls in the "main" routine.
Unfortunately, this doesn't work with the runtime version of IDL
and neither with the full version.
Apparently linkimage has to be used from the top level command
line and can't be used in subroutines. Any idea how to
circumvent this with IDL runtime?
