RE: [MacPerl]How to access C/C++ routines..

["Velasquez, Carlos" <carlos.velasquez@ssmb.com>]

Thanks for your expertise Arved, I could sure use it (and I am sure other
out in the Perl world could to.) I will use your suggestions and give it a
shot. I think its great that a you are putting a book out on SWIG (actually,
for my own Mac purposes, I am happy to hear that MacSWIG exists)

Is MacSWIG part of the MacPerl distribution or can I download it from
somewhere?

Carlos

P.S. Since SWIG involves compiling the header files, can I user MPW and it's
associated compilers or should I get MetroWorks?
