I hava a build problem upgrading Mythtv to 0.28.1-r1 [1] on an ~amd64 system. The problem is related to a glibc API change [2] introduced in glibc-2.24 and still present in glibc-2.25. So I'm thinking to try the build with an older glibc version.
Downgrading the system to glibc to 2.23-r3 means trouble? If not, an emerge @preserved-rebuild after the downgrade will be sufficient to not break the rest of the system? I suppose a quickpkg of the whole world before the downgrade would be a good idea, just in case... thanks, raffaele [1] https://bugs.gentoo.org/show_bug.cgi?id=604430 [2] https://bugs.gentoo.org/show_bug.cgi?id=575232
