Seconded, thirded, fourthed, fifthed, and nthed. I know some people do not care for as-needed at all, but it's advantages far outweigh it's problems. I've been using it almost since it first became available under Gentoo. When I updated expat, my rebuilds came out to less than 10 packages. I should have saved the outputted list.

I concur. Though I haven't set as-needed system wide. Instead, I am using bashrc to selectively apply as-needed to kde-base and kde-misc category packages only.

I only had a handful of packages actually needing a rebuild.

Apropos of nothing, I've decided 'outputted' is a terrible past participle, and I won't be using it again.

Anybody got the x11-libs/gtk+-2.10.13 working with this package?

For me it seems to fail on a utility that comes with the package or I don't understand what dependency I should fix.
I skipped it for a start and are continuing with the rest in revdep-rebuild so it might be solved later on.

The message I got is:

gtk+ seems to get fixed if you rebuild fontconfig and pango, then gtk+. Since you're skipping it, fontconfig and pango will probably get rebuilt towards the end of the revdep-rebuild.

You realize that that guide was written quite a while ago, right? Currently, very few things have outstanding problems with --as-needed. Many of the open bugs actually have fixes, they just haven't been committed yet, and at least a couple of the bugs currently blamed on --as-needed really have nothing to do with --as-needed at all. They just haven't been closed yet. And that bit about not reporting any problems to Bugzilla? Yeah, whatever:

I have tried most suggestion in this thread but no good. I had a new system up and running kde-meta 3.5 on 2.6.22-gentoo-r8 64bit system. It was quite a feat until I believe I did emerge -uDn world. After rebooting I got the the message could not find kdeinit.
Hadn't a clue what happened until I got to this thread but I'm afraid I am not any wiser. When I run revdep-rebuild -X I get all the kde broken and when it tries to emerge the first package which was kdelibs it failed, also the next when I did --skipfirst.

If no one can give me the instruction on how to fix this then can I get rid of kde-meta and re emerge it. If that's no good can I unmerge kde and emerge gnome? What is the commands.

I have used gentoo for the past couple of years and despite the sometimes hassle of emerge failures and long emerges I found gentoo the best distro and great help. But this is pretty bad and I would agree with a previous person that these type of arguments and opinions don't help the novices.

PS I have downgraded expat and put version 2.0.1 in package.mask. Doing revdep-rebuild -X and at the moment kdelibs has emerged but theres 210 to go. If successful when do I unmask expat 2.0.1?

beso_1717 Thanks for the reply. I put expat-2.0.1 into mask and now I have kde up and running. So I am pretty scared to try yours advise but I prob will try.

Anyway forgive my naive questions but when you say livexpat2 I believe thats expat? Also it's add LDFLAGS="-Wl,--as-needed" to make.conf and also what package is shared-mime-libs, what do I emerge?

After going through your advice, I also did an equery of expat and emerged most of them too, finally cairo pango and gtk+. Then revdep-rebuild -p brought up practically all of kde-meta As you said I will try emerging all non kde stuff first but that's not much. There are over 200 packages to upgrade but I will try the couple of none kde stuff first. I then removed the -p and so far kdelibs and 12 others are emerging ok.

Its a long way yet but it's looking good.

Most of the emerges are recognising --as-needed option in make.conf. Do I keep this option in all the time?

libexpat2 is expat-2.0 versions.

beso_1717 Finally done and got

Dynamic linking on your system is consistent... All done.

Thanks for the help

By the way there doesn't seem to be share-mime-libs
# emerge -pv shared-mime-libs

These are the packages that would be merged, in order:

Calculating dependencies /
emerge: there are no ebuilds to satisfy "shared-mime-libs". but there is a shared-mime-info.

I think I'm having similar issues with pango and libexpat (https://forums.gentoo.org/viewtopic-t-602948.html).
If you find a solution, please let me know.

I want to say, that expat is A REAL SHIT! It absolutely broky my system and it can't be fixed by emerge or revdep-rebuild because for fixing sistem after this shitty ebukd deleted libexpat.so.0 I need rebuild kdelibs, which always fails because of libexpat.so.0 absence (I tried enabling --as-needed, this doesn't change anything)

KiberGus,

There were two very different solutions posted in this thread.

My solution was to make a copy of the old libexpat that could be used to bootstrap through the problems you are encountering. The other solution posted by VinzC uses ldd and some logic to determine the proper emerge order to get around the bottleneck.

The problem is that some of the build-time tools rely were made with the old libexpat. They got broken when the new libexpat was emerged. But none of the existing ebuilds record build-time dependencies, they only list run-time dependencies so Portage is clueless about what the proper order should be. My solution lets both libexpats exist on the system at the same time so the build-time expat dependencies don't matter. The other solution involves manually figuring out what the proper emerge order should be and then emerging packages in that order.
