new virtual/pkgconfig to support lighter alternatives
the canonical pkg-config is getting fat. it requires glib-2. it runs pkg-
config when building. glib-2 requires pkg-config. whee.

for our normal systems, this isn't a big deal. but we'd like to enable a
lighter alternative for embedded/alternative systems. as such, i'd like to
introduce a virtual/pkgconfig that allows for selection of simpler (but
compatible) implementations.

we've got an implementation in perl (i'm not interested in), but there is also
"pkg-config-lite" and "pkgconf". they should be compatible with the canonical
pkg-config. they aren't yet in the tree, but will be once we agree on this
topic.

any comments ?

I'd just like to say, i'm also an Atheme project member and I have
authorisation from nenolod (the primary pkgconf developer) to make
changes and stuff, so I can upstream any changes necessary to make
pkgconf work for us.

that sounds really good. i sent you some patches ;).

however, it's missing pkg.m4. any thoughts on that ?

The patches look pretty good. As far as the solution for pkg.m4...I
just gave it a second look and noticed it's GPLv2+ which means the
license is compatible with pkgconf's (I thought it was GPLv3, which
would've meant it wasn't compatible)...We'll work on getting those
patches and the pkg.m4 in the tree and getting a 0.2 release rolled
out in the next day or 2.

I just sent a couple of patches to pkg-config to update the m4 with some
additional macros to provide stock --with-foo, I guess they will be
useful for you as well, if you import it before I can send you the same
patchset.

Maybe we should provide it independently in some other package.
Considering the implementations are supposed to be compatible, the .m4
file should work fine with all of them. And we'll create same configure
files independently of which impl particular user uses.

Well since the 3 primary implementations (fd.o pkg-config,
pkg-config-lite and pkgconf-0.2) now provide it, I don't see a huge
use for a seperate package. Also, the pkg.m4 used by all 3 seems to be
identical so...

i debated that, but i'd rather not split the canonical pkg-config package into
(quite literally) two files. it makes upgrading dev-util/pkgconfig more of a
hassle, and having these re-implementations take care of things themselves
seems to be easier atm. if that ends up not being the case, we can always
revisit ... the current implementation doesn't preclude splitting.

there are ones that try to be compatible, but are not. at this stage,
the virtual would only include dev-util/pkgconfig.

summarizing:

+1 for creating the virtual and migrating the tree to use
virtual/pkgconfig. although, on the otherhand, you could just use
package.provided for thesetype of unsupported experiments (like i'm
doing with pkgconfig-openbsd)

-1 for adding anything even slightly incompatible to the virtual

[1] pkgconf is not compatible as per Comment #5 of bug 413849. needs to
follow same version scheme as f.d.o's pkg-config.

[2] pkg-config-lite should be punted from tree as per bug 414101,
unnecessarily bundling glib code. there is no real problem with using
external glib. not liking it doesn't make it a problem. it's perfectly
bootstrappable and the bootstrapping is documented (plus ebuilds does
this for users so it's nothing you should even be thinking about...)

[3] pkgconfig-openbsd is incompatible in many ways, for example, doesn't
pass -pthread/-lpthread properly and breaks on -Wl,--as-needed systems.
take a wild guess why I didn't add virtual for this in the first place...

not compatible != wrong. There is NO CASE in which a developer would
hit this bug and customize their check in a way that would make it
only work with fd.o pkg-config. In *EVERY* real-world case, the
pkgconf behaviour would work just as well or better.

Maybe if pkgconf proves really good we could finally add pkg-config dep
to @system...

Uh no...
I thought we are in process of minimizing @system and correcting
dependencies in ebuilds accordingly
--depclean should be able to clean out things like pkg-config which are
not needed at runtime

yarp. i think we've managed to whittle down @system to mostly runtime only
packages at this point. don't want to reverse that trend.

if we split epatch out of eutils.eclass and into epatch.eclass, we could
probably get `patch` out of @system too. but maybe that's crazy talk.

ok, with no one against the virtual, i'll implement it

there seems to be miscommunication there. it's compatible.

not getting punted. what little glib code it bundles (and it really is quite
little) is hand extracted. it doesn't just drop the glib tarball in there.

would be nice if the eglib replacement (that bluez used to use) grew legs ...
then we could even use that.

otherwise, much of the glib funcs are brain dead simple and can be replaced
with #defines. g_free() for example is a waste of space.

glib-2 is not an acceptable hard requirement. its hard requirement on full
locale/multibyte support is a non-starter.

I would vote for it!

I feel ill to bootstrap glib and pkg-config. It feels worse to call for
a equal foot as gcc/binutils/glibc.

http://article.gmane.org/gmane.comp.gnome.gtk%2B.devel.general/21523

pkg-config's functionality is too simple to be involved with this chaos.

Looking forward to it.

pkg-config-lite and pkgconf are in the tree now, and there is a
virtual/pkgconfig which allows for these three packages (with the default
remaining the same).

i think the migration process will be:
- if you want to do the grunt work of converting random packages, go for it
- i'll update repoman to warn about packages depending on dev-util/pkgconfig
and suggest the virtual instead

If anyone would like to help me converting random packages/categories,
it would be GREATLY appreciated. This is difficult work and it has
literally taken up almost all of my free time for the past 2 days or
so, but I have well over half the tree converted.

just dev-util/pkgconfig -> virtual/pkgconfig and if the
dev-util/pkgconfig is versioned, i've been dropping the version since
0.26 is the only fd.o version in the tree and the alternatives are all
0.26 compatible.

Here's the list i've been working off of:
http://qa-reports.gentoo.org/output/genrdeps/dindex/dev-util/pkgconfig
(It's not the most up-to-date, but it works well enough.)

I am willing to finish this myself, but as I said, help would be
greatly appreciated.

Thanks

=dev-util/pkgconfig-9999 with USE="internal-glib" in Portage. I'm
hoping this will render the pkg-config-lite useless so we can drop it.

I'm very much intrested in knowing if this matches the requirements for
doing so, so I can decide whether I should be rolling also a snapshot
ebuild for ~arch or not.



And entirely different thing...

And I'll look into making pkgconfig-openbsd suitable for the virtual
today too, but I'm not expecting to KEYWORD it ever since even the
OpenBSD guys declare it only partly compatible in their docs/code.

Re: new virtual/pkgconfig to support lighter alternatives [In reply to]
I didn't mention this last night (probably because I was EXTREMELY
tired), but the entire gentoo-x86 tree has been converted to the
virtual (YAAAAYYYY!!! *kermitflail*). As long as you don't use any
overlays, you should now be able to switch your pkgconfig
implementation to pkgconf[pkg-config] or pkg-config-lite with no
problems.

Please give them (mainly pkgconf) a try and see if everything works. :D

Same USE="pkg-config" is now available in dev-util/pkgconfig-openbsd if
anyone is intrested in perl based version

It won't get KEYWORDS anytime soon, but I'm happily accepting patches
that are forwarded to OpenBSD bug tracking system too
