Looking at the options 1 use swig architecture to parse the C++ source code/headers and extract Pascal bindings - either by a rewrite or adapting the current effort 2 accommodate (and maintain) various compiler idiosyncracies from a distance... I'd say option 1 would be the easiest and best maintainable? - SWIG already provides infrastructure to parse the source files - People using Delphi would probably also be interested in fixing/patching bugs - On top of the previous point: changes in C/C++ standards/formats would not be our concern so much because those will be dealt with by the wider SWIG community - Of course, if swig is ever extended to support more languages, we get that for free Of course I understand it's very attractive to have everything in house and native in FPC, but I suspect the effort needed to develop/maintain it may outweigh that... @dliw: wasn't the Object Pascal module based on the Modula 3 module? IIRC recent posts on the swig mailing lists did indeed indicate the Modula 3 module was buggy in current SWIG. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
