Working in branches/one_make

Goals:

• most file generation should be done via make, not Config. To see what files are generated by your configure, make realclean; perl Configure.pl; svn st --no-ignore.
  • ext/Parrot-Embed/Makefile.PL should not be generated; it should just use Parrot::Config to get @ this config-time information.
• accurate build dependencies
• checkdepend.pl should verify perl dependencies.
• checkdepend.pl should verify pir deps.
• checkdepend.pl should be really be able to generate makefiles, not just verify them.
• checkdepend.pl should interpolate variables like make does when checking make. (not all at once at the end, but as-we-go.)
• recursive make is bad. Avoid it where possible, esp for anything built with the default target.

avoid make targets with two+ targets on the left; make is allowed to call this rule twice, which is probably not what you want.

Some tickets:

• #576
• #382 (done, needs mergeback)
• #1214
• #338
• #1285 (done, needs mergeback)
• #1418

Completed

• Specifically: eliminate parrot_include step.

20:41 <@Coke> there's a tools/dev/h2pasm.pl that does about 90% of what it 
              needs to.
20:41 <@Coke> er, s/dev/build/
20:41 <@Coke> each input file has multiple potential output files.
20:42 <@cotto> so you're filling in the other 90%.  Got it.
20:42 <@Coke> needs to be updated to take the output filename as an arg, and 
              then again so it only outputs the directives for /that/ output 
              file.
20:42 <@Coke> (and then tools/dev/h2perl.pl needs to be written.)
20:43 <@Coke> (which is basically a copy. refactor ahoy.)
20:43 <@cotto> nom
20:44 <@Coke> And I think I missed a few output files when I removed the 
              existing deps. should double check the input files for all the 
              potential out files and make sure they are all in the makefile.
20:45 <@Coke> writing this up...
