recursion in Gem - a tutorial - Pd-dev

18 Jul 2007


      I tried to make DLLs of nrepeat and nnrepeat, but it seems I'm too 
ignoramus to find out how to proceed, I've entered those lines in the 
msys shell
gcc -c nrepeat.c -o nrepeat.o
ld -export_dynamic -shared -I../../pd/src/ -o nrepeat.dll nrepeat.o 
../../pd/bin/pd.dll
the external is built without error, but couldn't be created:
\extra\nnrepeat.dll: couldn't load
  nnrepeat 1
the verbose option gives messages I've pain to interpret.
I've also tried to write a Makefile, it's attached, it does the same thing

Hi everyone,
I've been playing around with recursion in Gem, and thought I'd document 
my experiences.
You can download the patches here (Gzip'd Tar):
https://devel.goto10.org/dl.php?repname=maximus&path=%2Ftutorials%2Fgem-...
You will also need a couple of externals that you can download here 
(Gzip'd Tar, C source code only):
https://devel.goto10.org/dl.php?repname=maximus&path=%2Fclodlib%2F&r...
These externals are necessary because I haven't figured out a nice way 
to handle recursive re-entrancy in a Pd patch.  If I do I'll update the 
tutorial with the dependancy removed.
Screenshots are here, in case you're not near a computer with Pd+Gem:

Please let me know if you find it useful, or if you don't.  Thanks for 
your attention,
Claude
