[EMAIL PROTECTED], excerpted below, on  Tue, 01 Jul 2008
05:05:51 +0300:

 Over a year or two ago, it was communicated that it supposedly a policy
 that USE=static should only control if a package installs static
 libraries INSTEAD of shared libraries, and never to be used to control
 if static libraries are installed in _addition_ to shared ones or not.

That's as I understand it too.

 Packages were coerced to stop using USE=static for controlling that, and
 most of them ended up unconditionally installing both static and shared
 libraries. What's worse - they were told that if a package can provide
 both shared libraries and static libraries at once, it just MUST (or
 SHOULD) install them both instead of choosing to not ship the static
 libraries.

OK, but see below.

 End result that affects me: GNOME does not fit on LiveCD installation
 media anymore.

Ouch!

 So I'm proposing a USE=static-libs or similar to get out of this
 problem, and a lifting of the supposed (I wasn't around as a dev that
 long ago to know for sure) policy of having to install both instead of
 choosing to never install static libraries.

I'm not sure this is warranted.  See below.

 I am quite sure that absolutely nothing whatsoever uses about 97% of the
 static GNOME libraries we are now installing as an end result. [...]

Probably others than GNOME, too.

 There are packages in the tree that are required to install static
 libraries, or something else in the system breaks. So INSTALL_MASK=*.a
 is not a solution in my eyes.

This is the ticklish bit, but there's still a way around it for users 
(such as those trying to fit GNOME on a liveCD) that need it.  Useing 
portage's bashrc, setup a conditional that excepts packages that need 
static libs and set INSTALL_MASK='*.a' for everything else.

If you've not yet seen Ed Catmur's bashrc script setup, I+'5 d4 60mb!  
I don't personally find many of its capabilities useful, but his auto-
patching setup has sure come in handy, and the entire thing is just 
incredibly extensible on a nicely solid base. =8^)  It should make 
setting this up a breeze, and be handily expansible for 'most anything 
else you might come up with as well.  If it were me, I'd use that as a 
base and go from there utilizing the idea I suggested above.

Additionally, you don't mention whether you checked with them already or 
not, but releng and subprojects may have some suggestions in this area.

Thus Mart's effort to bring it to gentoo-dev :)

No, it was pointed out that this cannot be done for LiveCD material, as 
the packages would have a different content as a regular install. So 
this is just out of the question.


For those wondering : find /usr/lib64 -name *.a | xargs du -ch will 
tell you how much disk space is wasted by static libraries.


On my Gnome box, this is 246M. I know we won't be able to bring this to 
0, but having it closer to 10~20M is a very worthy goal imho.

Hi,

snip

I'm really curious to know why a new (global) useflag couldn't
do the trick.

Let's say, we introduce a new useflag called static-libs and
enable it by defaulin all profiles. Then we can have a look at
the lib packages step by step and add support when it seems 
useful there and test out carefully. There's no presure to this
for the whole distro at once.

Read Mart's mail again, that's exactly what he's proposing.

And if no-one objects, I'll be working this inside the gnome2 eclass 
(with review on this list before the final commit of course) to see how 
things should be handled.


Cheers
