Bug 646108 – sys-libs/glibc-2.26 can't permit to rollback to 2.25; with 2.26: compatibility problems in /usr/include/bits/floatn.h definitions of "float128" checked by packages dependent on all versions of Nvidia cuda

• Status: RESOLVED DUPLICATE of bug 638230
• Product: Gentoo Linux

[Description Ivan Dorna 2018-01-30 08:44:25 UTC]

portage can't permit rollback from sys-libs/glibc-2.26 to 2.25 due system braking check (good!) but if the system it's updated to glibc 2.26 there are compatibility problems in /usr/include/bits/floatn.h definitions of "float128"  checked by packages dependent on all versions of Nvidia cuda 8.x 9.0.x 9.1.x.

Seems the problem it's "only" related to header definitions of float128

I know that it's not (probably) strictly a bug of sys-libs/glibc a but cause a base system incompatibility problem without the possibility to rollback, so can be a nice thing have a patch to provide system compatibility about glibc-2.25 and glibc-2.26 about float128 definition.

I report other links as bibliography of the problem, an example of compilation, 
and emerge --info result.

This bug it's probably related to: #638230 on gentoo bugs.

nvidia-cuda-* has a problem. We fix that problem, not glibc preventing rollbacks.
