Hello Nathann, William, Simon, Bjarke, Robert, and all who read this
thread,
I need some help, too!
For ages I have been trying to create some kind of tutorial "example C
library", answering exactly these questions of how to integrate some
functionality written originally in C into Sage via Cython. I already
put quite some work into this.
However, up to now, I don't seem to have found the right shape of how
to bundle this information together: as documented source code, extra
spkg, some helper script(s) from which you can read off certain
necessary steps, ...
Before I go into any details --- who of you would like to discuss with
me any next steps, and/or the general direction to go?
Cheers,
gsw
