We need a new slot for dev-libs/mpfr-4.0.0. Otherwise we cannot ensure that users have a clean upgrade path that doesn't break gcc during the upgrade process. Masking new 4.0.0 package for now to avoid larger fallout. commit e174da06065cffc1b3cb099298a69338c1a7d7d2 (HEAD -> master, origin/master, origin/HEAD, blubb2) Author: Matthias Maier <tamiko@gentoo.org> Date: Tue Dec 26 10:44:50 2017 -0600 profiles: Mask dev-libs/mpfr due to soname bump

(In reply to Ivan from comment #2) > Well, it just broke gcc for me. I am sorry to hear that. The easiest fix for this situation is to recover /usr/lib64/libmpfr.so.4 and /usr/lib64/libmpfr.so.4.* from a backup. If that doesn't work I verified that the following dirty hack works: [ !! Only do this if you cannot resurrect libmpfr.so.4.* from a backup !! ] # ln -s /usr/lib64/libmpfr.so.6.0.0 /usr/lib64/libmpfr.so.4 # emerge -1 gcc # rm /usr/lib64/libmpfr.so.4

Ah, that comment came a moment too late. For all with FEATURES="preserve-libs" - your gcc works just fine. Just downgrade mpfr to the latest stable version (that has libmpfr.so.4 as soname). No need to recompile or temporarily symlink a library.
As a first step, I've committed the patch below. For slotting in the eclass to work, we need EAPI=5. Currently gcc-4.7.4, 4.8.5 and 5.4.0-r3 are on EAPI=4. I'm going to test bumping those versions of gcc to EAPI=5 and then add slotting to the eclass. commit f928b8697a9a7dbcac313bc350c76e5967febfea (HEAD -> master) Author: Anthony G.

Might be an interesting commit I've came accross: https://bugs.gentoo.org/attachment.cgi?id=511700 I also attached an updated ebuild for mpc with some additional cherry-picked patched. Feel free to employ!
toolchain.eclass is now up to EAPI=5 which allows for slots. i'll try adding the slot operators in a couple days and testing.

Thank you :) You'll notice I added slots/sublots to dev-libs/mpc. The other libraries already have them: dev-libs/mpfr, dev-libs/cloog, dev-libs/isl.
The slot operator worked quite well with my mathematical packages that depends on mpfr. But with libmpfr.so.3 being preserved, gcc (at least 7.2.0) is susceptible to ICE until rebuilt against the new mpfr. This simple code leads to an ICE when compiled with g++ #include <complex> auto inf = 1.0 / std::complex<double>(); This is infact due to the rebuild of mpc without changing the soname. So gcc has direct link to libmpfr.so.3 and an indirect one to libmpfr.so.4 courtesy of an immediately rebuilt mpc. See a concrete example over at https://trac.sagemath.org/ticket/24599

See a concrete example over at > https://trac.sagemath.org/ticket/24599 Thanks for the testing and research. I was afraid of something like this. We're going to have to be more clever about how we make use of the slot/subslot operators.
I don't think it is that bad. It is certainly inconvenient. For info I maintain the sage-on-gentoo overlay, the next release of sage is using mpfr-4 (beta release have already switched which is why I am having fun with this right now). So a number of users will unmask mpfr-4, if it isn't already, probably sometimes towards the end of February. I will pass the message to end users as well as I can, fortunately the compiler is not totally broken in most cases, I just may have a number of duplicate issues about ICE while rebuilding giac.

Any clues on when a mpfr-4.x.x will leave package.mask?
