[gentoo-dev] ebuild inheritance question

[Caleb Tennis]

Hi,

In trying to track down some of the dependency problems/mess in the KDE stuff, 
I come to you with a question:

How are DEPEND="" statements handled when inheriting an eclass?  That is, if I 
do this:

inherit blah

DEPEND="pkg1 pkg2"

How does the inheritance of blah have an effect on the DEPEND="".  Does it 
just overwrite it, does it append.. etc?  Or is it "proper" to tack in a 
DEPEND="$DEPEND pkg1 pkg2"?  What about RDEPEND automagically getting DEPEND 
values?

Sorry if this is stupidly obvious, but it's not addressed in the docs and 
nobody has been able to answer the question thus far.

Thanks,
Caleb

it's not stupid nor is it really a 'someone screwed up big' ...

newXdepend has some history behind it but it seems you only care about the 
now ... i think danamark will have some issues when he gets back but i hope 
that it turns out well ...

the way dependencies work right now with respect to eclasses is pretty 
simple ...

eclasses ALWAYS use newdepend, newrdepend, newpdepend, newcdepend ... they 
should NEVER have DEPEND= or similar ...
flip side of the coin is that ebuilds should not be using the newXdepend, they 
should be using DEPEND= ...

i think thats clear enough so i'll leave this alone ;)

I don't think this is true.  If you look at the existing eclasses you
can see a lot of DEPEND= in there.
