[gentoo-user] hacking an ebuild

[gentoo-user] hacking an ebuild

[James]

Hello,


The devs seems to be busy. Also, I should have learn this some time
ago anyway. There is a existing ebuild for JFFNMS, but, it is masked
for amd64. Is there a guide I can follow to use an x86 ebuild and
create an amd64 derivative ebuild? Since it uses php and other high
level software, I would not think that this is a terrible difficult
process....?

If not, can somebody briefly itemized what needs to be done,
in very general terms, to hack together an ebuild for amd64
when one exist for x86?

I took a quick look inside the ebuils. Nothing there seems amd64 
specific, so here's how I would proceed;

Create a user overlay in the usual place - $PORTDIR/local/
Copy the ebuild there as normal
modify KEYWORDS="~x86 ~amd64
Check that all the dependencies have amd64 ebuilds as well
emerge jffnms and see what happens

Ok this sounds like just the sort of advise
I was looking for. If I run into
trouble I'll post again.


Thanks Alan,

What? Why? Just add 'net-analyzer/jffnms ~x86' 
to /etc/portage/package.keywords? No matter what the KEYWORDS of an ebuild 
are (or aren't) they can be accepted by a proper entry in package.keywords 
(** if empty)...

I think the problem here is that the package is masked, not marked as 
unstable; that's the reason to create a new ebuild not affected by the 
general portage.mask... Am I right?

No. First of all it's not masked. Secondly if it was masked it could be 
unmasked through /etc/portage/package.unmask...

<sigh>

Yes, you are right. What was I thinking? It must have been late at the 
time.

On amd64?

It tried this. It allowed the standard page to be emerge, but
it fails to compile
dev-libs/apr-util-0.9.12  fails to compile, so, jffnms cannot compile.

Not sure what you are saying here. Can you give me the explicit line
to add to the /etc/portage/package.keywords


confused....

<section-name>/<package-name> * ~* **

This will make the package visible under just about any circumstance, 
whether it is stable, unstable or not keyworded for your arch.

see 'man 5 portage', section package.keywords around about line 330 for 
more info. This feature is relatively new and if you last read the 
howtos some time ago (like me...) you might not be aware of it yet

* accepts any stable keyword. ~* accepts any testing keyword. -* accepts -* 
keywords. ** accepts even if there are no keywords at all (which means 
basically anything will be accepted)... I'd never use ** where it isn't 
necessary...

It's also redundant (in that ** will cover anything anyway)... ;)

Only ** was added recently. At the same time KEYWORDS="-*" was banned in 
favour of KEYWORDS="".

Hello Alan,

That is a very cool bit of detail you have provided. 
Most excellent! Now that I have that trick, I have
several things to revisit....

thx

Well after using alan's suggestion and getting JFFNMS to compile
I just had to try this out. It worked too!

Can you explain why using ~x86 on an amd64 machine works
in the /etc/portage/package.keywords file? 
It seem I need to do some more reading....


> > dev-libs/apr-util-0.9.12  fails to compile, so, jffnms cannot compile.
> Fails how?

Paraphrased, it said that the Berkeley database was not installed. 
Looking at the  available packages ('eix berkeley' and then 'eix db')
I figured out that is was because that berkdb is a general system
flag I set in 'make.conf'. So for 'apr-util' in the 'package.use' 
file I just removed this flag (-berkdb). I'm not certain what effect
this will have on my system or JFFNMS, if any at all.... Once this
was fixed using your method or alan's method, JFFNMS compiled.


Now JFFNMS is installed and it's time to configure it and test it.
thanks for all of the help.....

James

Because that's the keyword the ebuild has? Why wouldn't it? package.keywords 
specifies what keywords you are willing to accept for a given package atom...
