Re: Reverting to an old version of libstdc++6

This weekend I upgraded, and libstdc++6 went from
4.5.2-4 ->  4.6.0-2.

(1) how do I determine what version of libstdc++6
that the previous debian version of that package was using?
That, is, the current package provides the file
/usr/lib/libstdc++.so.6.0.15 and a link
/usr/lib/libstdc++.so.6 ->  libstdc++.so.6.0.15.
I assume the previous debian version did the same,
but with some other file, maybe libstdc++.so.6.0.14?
How do I find out what that file was?


I went to snapshot.debian.org, searched for the binary package libstd++6, and grabbed the .deb file for version 4.5.2-4 on amd64. I opened that deb-file (with the decompression program in gnome) and it contained /usr/lib/libstdc++.so.6 and /usr/lib/libstdc++.so.6.0.14, as you expected.

(2) How do I locate and install
the previous version from a debian repository?


Download the .deb from snapshots.debian.org and install. The normal warnings and disclaimers when downgrading library packages all apply.

<http://snapshot.debian.org/package/gcc-4.5/4.5.2-4/#libstdc:2b::2b:6_4.5.2-4>

Hope it helps
