Hi everyone, In the past I've had some success generating Java libraries for Bigloo, wrapping C-based libraries such as GLPK and Graphviz (even posted them on this list, at some point:-). As I remember, this involved SWIG and hacking Cigloo-generated directives. So in the end you could use the library in either interpreter, with the C backend and also with the Java backend (and .Net, when the backend was still available). Even tried to move the whole thing to Windows to check if it was working (it did, with compatible Windows DLLs of the involved libraries).
So depending on your will to get it done ... (I do remember the process was quite fragile).
