Hallo!
AFAIK there are two packages: SWIG and G-Wrap. Although I only use SWIG,
some of the differences seem to be:
- SWIG supports interfaces for several scripting languages, not only for
guile. I contrast, G-Wrap generates only wrappers for scheme (maybe even
only for guile?)
- SWIG has rudimentary (but for me sufficiently working) support for C++,
which doesn't seem to be true of G-Wrap. Maybe meanwhile wrappers for
C++ exist?
There are probably some aspects in favor of G-Wrap, but I especially
remember these points, since they were crucial for me at the time I had to
decide which packet to use.
However, for GNOME I suggest considering SWIG, since ISTR that one of the
GNOME issues is not to be fixed to a single language. If you are
interested, I could send you some examples of how I usually wrap functions
and data structures with SWIG.
* Note to the maintainers: If there is interest, I could work these
examples into a little tutorial. Some time ago I sent some comments about
the guile web sites, stating the lack of examples as one of the big
problems for advocating guile.
Best regards,
Dirk Herrmann
