Incurring the risk of being too much off-topic, I'll just say that I use the Gambit-C Scheme compiler to produce C code that I link with my C driver code. I need to write the driver ("main" and friends) in C because my software is compiled as a Windows service or POSIX daemon, which requires special care. But of course you must link in the Scheme runtime, with the garbage collector, Scheme data types etc. Cheers, -- -alex http://www.ventonegro.org/ _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
