Following the pattern I've seen in widespread use, I use rake in my Ruby projects for most high-level tasks (running specs, building gems etc) and mkmf to make C extension makefiles. mkmf works great for the simple case where you just want to compile some C files and link to some libraries; the default behaviour seems to handle most things automatically. But what if I want to do some more sophisticated rake-like stuff where I manually specify dependencies? For example: * Start with ANTLR grammar file "Grammar.g" * Whenever this file is updated, have to run ANTLR on it and this regenerates new "GrammarLexer.c" and "GrammarParser.c" files * In this case want to rebuild the extension Is there a way to do this using mkmf? Or do I have to manually tweak the generated Makefile myself? Cheers, Wincent
