I've been doing this dynamically. I define the message class in MyClass.h
and MyClass.cc (using Ptolemy's IntVecData class as a template). Note:
Because I'm using Linux, I have to put all the member definitions in the .h
file, and the only lines in the .cc file are
______________________
#ifdef __GNUG__
#pragma implementation
#endif
#include "MyClass.h"
_______________________
I believe this is a gnu g++ bug.
Then I include MyClass.h & MyClass.cc in the star's .pl file. I load the
star with Shift-L. If I change the MyClass files, I delete all the files
that were created when I compiled my star (eg. SDFStar.cc, SDFStar.h,
SDFStar.o... .o is the most important to delete) leaving only the
SDFStar.pl file. Then from Ptolemy I re-compile my star with Shift-L.
One important point is that if I make any changes to MyClass, I find all
stars with references to the class using
nm -o *.o | grep MyClass
and delete all their files except the .pl files, and recompile them as well.
For this reason, it's not good to use the message class in a lot of stars
until you feel you won't be changing it.
Hope this helps.
