Is there any makefile guru who could (maybe use some fancy tool to) fix the dependencies?
Having to recompile everything for each small change is annoying.

I assume you mean the windows one?  dmc is fast enough that recompiling takes very little time, especially compared to running the test suites.  So long as you don't modify any header files you shouldn't need to recompile everything anyway...

iirc Walter's complaint is that the makefiles quickly get out of sync anyway, so it's a better habit to use make clean constantly regardless...

Nope, Linux.

Automating it on one machine should be enough.

Ah ok, different issue.

Automate checking it and add that as one of the tests.

I don't know about other people but something better than 80% (might even be north of 95%) of builds I run give errors (I tend to use compiler errors as a static analyses tool) and even when things build, I avoid running more than a few seconds worth of test until I think the codes correct.

Run a clean build and test every so often (several times per hour) but MOST builds should be incremental so as to be as fast as can be managed.

A simple and effective way to do it with gcc is to generate dependency files (*.dep) during compilation with -MD/-MF and include these into the makefile with

-include *.dep

That sounds sound :)

Yep, even Clang needs half a minute to do a full build for me.
