[gentoo-user] Changing glibc
Hi, I am using a closed source software package on my 64 bit gentoo linux system. The software package is beyond compare by scooter soft. Because of the way this package is built, it needs a specially patched version of glibc. I have patched my existing glibc version (2.18) and have been avoiding updating my glibc since. Now I am wondering whether the latest update of bcompare will work with the latest glibc (2.19). So, if I upgrade to 2.19 and the package doesn't work, how can I go back to the working, patched 2.18? I know that portage issues the most scary warnings when you try to downgrade glibc. So what does the community recommend? -- Timur
Re: [gentoo-user] Changing glibc
One option is to copy the glibc version you want to some other directory and set LD_LIBRARY_PATH before starting the executable. Running ldd on all the executables/shared libraries in question should give you a list of all the shared libraries you might need to copy to a safe place.

You should be able to downgrade glibc, provided that you haven't built and installed any new packages following the transition from glibc-2.18 to glibc-2.19. That said, I would suggest that you back up the root filesystem as a contingency measure. Still, why not test bcompare in a chroot? The latest stage3 tarball probably includes glibc-2.19 by now. --Kerin

In cases like that I would do either of the following: 1) Run it inside a VM 2) run it inside a chroot That way you can easily keep everything updated except for that application. -- Joost -- Sent from my Android device with K-9 Mail.

Or better still run it inside a container. Gives you most of the benefits of both a VM and a chroot. It isn't as isolated as a VM, but it is more isolated than just running the thing on your system. It is also easy to bind-mount your home directory if that is helpful. A container replaces the entire userspace, potentially including init as well. So, as long as your kernel is compatible and you're not doing anything too crazy with devices, this should solve your compatibility issues. -- Rich
