emerge --update --deep world (pango) broke system

Message

I tried to do a system update by running:

emerge --update --deep world

However, the update stopped running while compiling a pango update and broke my gnome environment.

I haven't got a clue how to fix this. I ran

Code: Select all

revdep-rebuild

but that didn't fix it.

Code: Select all

emerge --update --deep world

still fails on the pango package.

Could you paste the error message when pango fails?

You've fallen to the expat ABI upgrade:

Code: Select all

emerge portage gentoolkit
emerge -1 sys-devel/gettext dev-perl/XML-Parser sys-devel/libtool
emerge -1 sys-apps/dbus sys-apps/hal x11-libs/cairo x11-libs/pango x11-libs/gtk+
revdep-rebuild -X -L libexpat.so.0
revdep-rebuild -i

HTH.

@mark_alec: This is the last part of the compile text

@steveL: will your code example work? In your edit you say 'if you have apache', I don't have apache.

Er the apache bit is a link to another post with more info if you do have apache, so don't worry about it. Try the code, and see what happens: if you want more immediate help log in to irc.freenode.org channel #gentoo as they have been dealing with this for weeks.

Do a
rm -rf .revdep*
revdep-rebuild -X

Er that's pretty much what revdep-rebuild -i does (new version does packagenames by default, but I don't know if that's in stable.) The -i flag tells it to ignore files from a previous run. You may be right that this would help at the start.

@steveL and xbmodder

Both suggested repair option fail to work. I still get an error when trying to install the pango ebuild. Any suggestions?

Try this again:

Code: Select all

emerge --sync
revdep-rebuild -X -i --library=libexpat.so.0

@bblount

That didn't work either... Is there any way to fix this lib expat bug that broke my system.....???

I don't know if anyone solved this, but there is a pre-built binary in the pango distribution that depends on libexpat.so.0. You can get around this as follows:

Code: Select all

cd /usr/lib
ln -s libexpat.so.1.5.2 libexpat.so.0
emerge -u pango
unlink libexpat.so.0

Don't forget to do the unlink before you emerge anything else or you will have big problems.

Hope this helps.

@sbrenneis

Your code helped to emerge pango; great! Cheers for that. What to do now, because an emerge --update --deep world still doens't emerge all the packages?
