Make is not painful,... Yes it is. The only kind of dependency it can express is a build-dependency. No provision for expressing other things, like include-dependencies. Hence the need for layering all kinds of other cruft on top to get around this limitation.

make shmake Posted Feb 22, 2007 12:54 UTC (Thu) by nix (subscriber, #2304) [Link] Per-language dependency analysis plugins to make would be nice, I agree, probably conditionalized on pattern rules, e.g
%.c %.h: $(dependency-plugin c)
which loads, say, /usr/libexec/make/dependencies/c.so with a defined interface and uses it to append dependencies to .c and .h spotted in target lists...

As you found out, Make is not supposed to be a/b/c/d/e/f-language pre-processor. You ask that kind of information from the compiler of the corresponding language. With C-language and GCC compiler you could use a rule like this:
# automatic include file dependencies
deps: $(SRCFILES)
gcc $(CPPFLAGS) -MM $^ > deps
-include deps
make shmake Posted Mar 1, 2007 19:54 UTC (Thu) by nix (subscriber, #2304) [Link] It would be nice if that sort of boilerplate could be generalized outsomehow. Mega-duplication (or the reliance on system-specific stuff like *BSD makefile fragments) both are nasty...
make shmake Posted Mar 2, 2007 23:33 UTC (Fri) by ldo (subscriber, #40946) [Link] Jam already has this sort of thing built-in. So much simpler than trying to add yet another layer of complexity on top of make.
make shmake Posted Mar 5, 2007 13:42 UTC (Mon) by nix (subscriber, #2304) [Link] jam strikes me more as a language to build build systems in than a build system.
I remember trying to set the equivalent of CFLAGS and prefix with Boost... it took a couple of dozen lines of patches to the build system just to do that, and a couple of patches to the jam source bundled with Boost.
Sorry, but I prefer Automake's nasty verbose makefiles to *that*.
