Re: [Warzone-dev] Automatic dependencies
Most of the sed code is just magic that I copied from somewhere else, probably http://make.paulandlesley.org/autodep.html which is a must-read. Does that code run always before the %.o: %.c rule is applied to any file? Yes. if we want Makefile.raw to be able to run from within a dos shell (no sed for example). No sed is just the beginning. Does anything of any complexity really run in a DOS shell? I would guess even just make would struggle, with different path delimiters and all that.

What exactly does this sed magic do, actually? To me it looks like: - Remove comentary lines - ? - Remove ending backslashes - Remove empty lines - ? Is that all needed? I tested it a bit and didn't get any comments or empty lines. Ending backslashes don't seem evil to me, either.

I believe there are switches to make gcc do the same as makedepend, but a lot slower. I do not know about slower, but there is no need to add dependencies to files that are checked in, at least not if you use gcc -M. You mean that the dependency information is already there (in the .c files) so we should not commit it to SVN another time? The standard way to do this is, it seems, to create new, hidden files with dependency information for each .c file. In autohell, those are added as .Po files in a separate .deps directory. One advantage of this is that you do not need to check in changes to dependencies to the repository. This is a bit of a problem if we want Makefile.raw to be able to run from within a dos shell (no sed for example).
