You're almost there, I think.
I don't actually use Linkimage myself, but a colleague of mine in Perth
does. He got the following solution from RSI for using Linkimage with
runtime IDL:
In order to use linkimage routines they must be defined in main. Also, all
routines using these routines must be restored from a *separate* save file,
within the main procedure.
(I think that you still have to implement the second part of this, which will
just mean having a little .sav file for your MAIN routine and a second one for
the bulk of your application.)
e.g.,
pro main
linkimage, ...
linkimage, ...
restore,/routines,file='myapplication.sav'
start_prog
end
