Does anyone know if there's a version of makedepend(1) for UNIX that knows how to deal with C++? Thanks, Tim -- Timothy Jones tim@cs.columbia.edu (internet) Department of Computer Science ...!rutgers!columbia!cs!tim (usenet) Columbia University tim%cs@cuvmb (bitnet)

Why won't the one that deals with C work (its just a search for #include in
both cases, isn't it)?

Don't know if this is close to makedepend(1) (it's not on any machine that I use) but this script works fine for me. #! /bin/sh # @(#) $Id: mkdep,v 1.4 90/05/09 20:19:19 marc Exp $ # # Make C++ dependencies.

Why won't the one that deals with C work (its just a search for #include in both cases, isn't it)? Specifically, I'm using g++, and the problem is that I get lots of 'unknown directive == "#elif defined..."' error messages, presumably caused by included files within my source file. Perhaps I just have an old version of makedepend which doesn't understand "elif" for some reason. Running g++ -M does the trick, but I can't use it to parse other source language files, like lex or yacc. I guess I can use the regular makedepend for that and combine the results of the two programs (sigh)... Tim
