 Well, I don't have web-reference at hand now, but there was a thread in
 gentoo-dev with the subject: Say no to static libraries!. Summarizing
 some ideas from there:
 
 1. Some packages will break if you build their deps with USE=static.
 This can be fixed when we start to use USE-deps in the tree.
 
 2. We already have mechanism to make what you want. Just drop
 EXTRA_ECONF=--disable-static into your make.conf and to workaround
 problem stated in point 1 use
 
 EXTRA_ECONF=${EXTRA_ECONF/--disable-static} 
 
 in /etc/portage/env/cat/pkg. (For those who interested  list of packages
 for which I have to filter --disable-static is in attachment).

I'm going to simply drop the remaining USE=static's where appropriate,
if upstreams choice is to disable static libraries, and we'll see even
later what to do about those that don't default to not building static
libraries. For now I stumbled on just gtk-engines.

That is, some GNOME packages make it their own business to override the
automake default of building both - they call AM_DISABLE_STATIC.
So for those I'll just drop any --{enable,disable}-static (as I notice)
and honor upstreams choice in not building static libraries. This also
means nothing uses or needs the static libraries because all GNOME
tinderboxes and jhbuild based development machines would scream in agony
if it broke anything.

 Well, I'm using EXTRA_ECONF for more then year now and I'd like to say
 that it's not perfect solution. Not all packages are autotools based and
 ignore --disable-static and now I have 103M of static libs on my
 desktop. So now I'm all for having static-libs USE flag. But please,
 don't do that on per-package base. Make an eclass for that. Think about
 not-autotools packages, and don't put it in the tree until we start
 using USE deps.

I know of absolutely no GNOME package that needs its static libraries
installed. Only exception is glib, but that is a lower level library,
not a GNOME one - there we explicitly enable it for syslog-ng possible
use primarily. And for glib I'm quite cool in enabling it always, as my
take on glib is that it's a standard C library that makes C actually
usable and powerful, just as libstdc++ makes C++ more powerful, and
should be universally available to all. Though an alternative would be
to install it in /lib, so that boot tools can use it and not need to
link statically - having syslog-ng in mind primarily.

 Thanks for reiterating this discussion. I wanted to return to it soon as
 seems that USE deps are really about to enter our life.

And now I'm reiterating it again the first time since 3 months.

 And BTW, seems that all gnome packages obey EXTRA_ECONF ;)

And probably G2CONF too, but we like to use that for ebuild use only -
we aren't sure we have G2CONF=${G2CONF} foo everywhere, etc.

[gentoo-dev] RFC: Installation of static libraries, USE=static-libs proposal

2008-06-30 Thread Mart Raudsepp
Hello again,


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.

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


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 am quite sure that absolutely nothing whatsoever uses about 97% of the
static GNOME libraries we are now installing as an end result. How can I
be sure? Because everything worked just fine when static libraries
weren't installed in the past thanks to that not happening from
USE=static missing on most systems for years, and you'd have to be quite
crazy if you required static version of desktop libraries with well
established and followed ABI guarantees.

Those that aren't absolutely sure that there is no use case for static
libraries, could then use a USE=static-libs or similar to not
unnecessarily install static libraries that are not going to ever be
used. And LiveCD media could avoid all these static libraries, that it
currently has to ship just because the packages by default install that
cruft for no real technical reason (and it has to follow that due to
GRPs).
I would use USE=static-libs on packages like gtkmm, that have good
reasons to provide a static version - it allows Gentoo users that would
like to do commercial or universal C++ based development against Gentoo
system packages, as it avoids feared libstdc++ ABI breaks (there's even
a request for it in bugzilla).



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.


Useful comments, thoughts, agreements?



I have had some additional ideas for handling static libraries better at
a package manager level, but those still need to be fleshed out and put
into writing.
Things like possibility to rebuild all packages that link to a static
library that was now upgraded, so the higher level package could use a
relinking to benefit from the bug fixes from the new library; optional
ability to install only the type of library currently needed - shared or
static, etc. Much of it goes to blue-sky ideas though with minimal
benefit for normal desktop/server systems and potentially high
maintenance effort, so I haven't put much effort into putting it into
writing. But maybe someone interested wants to chat on IRC on the topic.
