[Etherboot-developers] Makefile suggestion

[Marty C. <md...@et...>]

Hello All,

I was debugging some Makefile stuff ran into an interesting bug where 
the Roms file was not getting rebuilt based on changes to genrules.pl. 
My reading of the Makefile suggests that it should, but it wasn't.

I was thinking that in the "make clean" stanza of Makefile, we might 
want to add Roms, since it is generated from NIC using genrules.pl.

So we would have:

clean:
	$(RM) $(UTILS) bin/*.s bin/*.o bin/*.bin Roms

I think what might have happened is that I accidentally edited Roms 
after editing genrules.pl (but before I did a "make"), so genrules.pl 
was not run to regenerate Roms, which made the Makefile not work as 
expected.  Once I deleted Roms, it got regenerated.  I'm also thinking 
we might not want to distribute a pre-built Roms file with the 
distribution, so that it gets made when it is needed. Frankly, since 
Roms is Included in Makefile, I'm wondering whether "make" can sanely 
check Roms before it is Included.

I suppose this would necessitate people having Perl, so that is a 
consideration, but it is pretty common these days.

Food for thought. What do you think? I'm sure we have some Makefile 
wizards out there, since the $rom--% rules got in there ;)
