Gentoo design bug?

Dear all,

I managed to build a non-working gcc on my Powerbook. It just shamefully crashes during large compilations. And I only noticed it after it replaced the previous gcc version.

Well, I've just figured out there is no possibility to recover from such a problem nicely. If you somehow screw up, let's say, gcc, glibc or python, your only hope is to recover a working binary version from an install CD or a Debian or RPM package so that you can get out of trouble...

It would probably make sense for most of the systems around, to have a minimal protected statically-linked core to allow such a recovery in a nice way. What about

Grab a binary gcc package and install it with emerge -K

Yeah, and I think the portage tree includes a stand-alone version of portage for emergencies as well.

You need to manually download a .tar.bz2 file that contains precompiled binaries. I don't actually know where to get them, since I compile all my packages manually.
If you do find somewhere to get it, you can also set PORTAGE_BINHOST in make.conf. Then it will use that site as a binary mirror.

I know that for x86, gentoo provides separate cd's full of precompiled binaries and i think they do for PPC as well. check it out, and if they do set PORTAGE_BINHOST to your cdrom drive that the disc is in, then do the "emerge -K ...". AFAIK, there are no binary mirrors right now, so the only way is to use a cd. GOOD LUCK :wink:

[edit] I just checked and it looks like there are no binary cd's for PPC, im sorry :oops:

If all other fails, try getting another distribution's gcc package and manually installing it. Slackware and Debian packages should work, but I am not sure. Also, if you've got a spare system you could try emerging it with --buildpkg and then transferring that package to the broken system.
Good luck

Or you unpack a stage3 into an empty direcotry on your comp, chroot there and use quickpkg to make a binary package of it. That shouldn't take more than 10 minutes at most but you need a little more than 1 Gb free space.

Thanks Cuardin,

I hadn't thought about this option. That's by far the cleanest one as no PowerPC binary packages are available.

Regards..

Hm, perhaps a note should be placed in the docs that it is a good idea to make binary packages of gcc, glibc, portage and python and keep them in a good place.

There is also this FAQ: SA5: Things to not unmerge or remove.

There is an "emergency tarball" containing glibc, gcc, portage and python out there somewhere. If you give me a few minutes to find the link, I'll post it somewhere.

I am pretty sure that portage makes a quickpkg tarball automatically when upgrading one of those critical packages. Check your /usr/portage/packages/All
I did not check if it still does, that might have been removed.

Even if not, using quickpkg to backup known-working versions would be a good idea for anyone.

Unfortunately, all these ideas fail if wget, tar or [g,b]zip stop working.
