[gentoo-user] glibc 2.12.1-r1 seems to not be working correctly
Hi. I am running the unstable gentoo 32-bit and today I emerged -- amoung other packages in a system update -- glibc-2.12.1-r1, however after doing this at least one package had an undefined reference to S_ISCHR. I tried to downgrade glibc, but apparently this is not supported and I am a bit stumped as to how to fix this problem. Any ideas on this would be appreciated. -- Your life is like a penny.

Looks like a real bad problem, I'm glad I did not update yet. http://blog.flameeyes.eu/2010/08/18/compounded-issues-in-glibc-2-12 has some explanation on this. I wonder how this glibx version did make it into ~arch. Any ideas on this would be appreciated. Don't know. Maybe wait a little and see if another new glibc fixes this, or the packages having issues with the new glibc might get updated. Wonko

Please check if it is already reported, and if not then please report a new bug, and if possible make it block this tracker bug: http://bugs.gentoo.org/show_bug.cgi?id=331665 A wild guess out of the blue would be that the error could be simply a missing include of stat.h in the package's sources. But there might be other omissions as well, so please provide more info. I think that unless API/ABIs were changed then the older, already installed version should still work just fine, as then the missing includes would only affect compile-time situation. -- Arttu V. -- Running Gentoo is like running with scissors

OK, I will check on that -- I am thinking that for that package a missing include will fix this, but I could shoot whoever broke this without thinking at all. I wonder if the failure of php to compile because my_compiler.h is missing has something to do with this also? -- Your life is like a penny. You're going to lose it.

There is a way to downgrade for the brave. quickpkg glibc move the 2.11.? version ebuild you want to your local overlay. Edit it and find the check that disallows downgrades. Comment it out. Mask glibc2.12 update glibc At this point it's probably very wise to rebuild at least system, then revdep- rebuild. Note that rebuilding system might fail in which case you are really up the creek.

I also changed my gcc before this update, I could certainly reverse that as well. It all depends on what tools you have available and how many packages were upgraded between yesterday and today. If you have tarballs for at least system in your packages dir, then just merge the old ones back. If not, then downgrade glibc and either emerge -e system or run revdep-rebuild. gcc is not a major issue, it simply builds runnable code and links to other stuff. As long as the ABI didn't change, and it didn't, gcc will not cause any relevant problems. The real problem is glibc which provides the C library. Almost everything links to that and it's interfaces can and do change. So packages built since that upgrade may well break with a downgrade. But like I said the best approach will depend on what packages are involved and you still haven't provided that list. I used to have a crystal ball that could gaze into your mind and your disk to find these answer, but ironically it too is now broken by the very same glibc upgrade you are dealing with. So you must look into this yourself. However, it's not all bad news - at least my fee to you will not increase. -- alan dot mckinnon at gmail dot com

I also changed my gcc before this update, I could certainly reverse that as well. you can also leave that glibc version in place. Only a few packages are affected, most are fixed already. Just sync and retry the failing package. No need to downgrade glibc and recompile a bunch of packages. Besides, between 2.12.1 and 2.12.0 you should not need to recompile anything.
