The existing guile module support the gh_ interface and the older version of the SCM interface. It also doesn't work with guiles current GC. It's entirely useless for the current version of guile. I had assumed that since SWIG still ships it, enough people care about legacy guile support to not want it broken. I've only just started looking into getting the test-suite working with my guile2 work, but I do intend on getting it to the point where it all passes. For me personally, the old guile module is no longer useful. However, guile 2.0 is not widely deployed in distributions yet and that may take some time. > BTW, there > is the swig -scm option for guile 1.6+.

The -scm support works by mapping the old SCM interface to the GH interface.. Almost all the scm_ calls used by the existing guile module are deprecated. I tried implementing and -scm2 option within the existing module but it was more awkward than I could bare. I'm not sure that there is going to be enormous support for this within the guile community either really. Guile 2 ships with a new FFI and using that is, obviosuly, of more interest to them. I've struggled wrapping legacy APIs with it though and SWIG really is rather good. -- Tristan Colgate-McFarlane ---- "You can get all your daily vitamins from 52 pints of guiness, and a glass of milk"
