> The alternative is to scan the sources using a custom parser, which is slower and more fragile. More fragile, yes, but I dispute the "slower" aspect. waf does this very well. In C you don't need to parse the entire program structure, you just need to parse what the preprocessor does. Also there's a difference between the complete set of header dependencies (notably #include statements within an #if or #ifdef) and a more sane but incomplete methodology for #include statements (don't do it within #if/#ifdef). Not sure whether this is a big enough difference to try to matter. |
