From: "W. Trevor King" <[email protected]>
When using `update_seed` to get a 20121213 stage3 from
libmpc.so.2 to libmpc.so.3, stage2 failed with:
/usr/libexec/gcc/i686-pc-linux-gnu/4.6.3/cc1:
error while loading shared libraries: libmpc.so.2:
cannot open shared object file: No such file or directory
This was due to an mpc version bump in the Portage tree that was not
present in the stage3 I used to seed stage1. Stage1 wasn't
recompiling GCC against the new mpc, so it ended up with GCC linking
against the old mpc. Heading into stage2, the old mpc (from the seed
stage3) was no longer present, so compilation crashed and burned.
To fix this, we should be extra agressive about rebuilding packages
when their dependencies change in stage1. The earlier update_seed
command was not catching the bumped mpc, so add:
--complete-graph --with-bdeps=y --rebuild-if-new-ver
to toughen things up.
This is a general dependency problem (not GCC specific), so I also
replaced the gcc target with:
@world @system
This leads to a lot of rebuilding, but it should be a stable and
general fix. With a general fix there should be no more need for
user-specific overrides via update_seed_command, but Gentoo is about
choice, so we keep the option. Use it at your own risk ;).
