Re: [gentoo-science] Emerge singular-3.1.6::sage-on-gentoo fails on gentoo-3.16.5 gcc 4.8.3 with graphite and lto

["François Bissey" <frp.bissey@gmail.com>]

If you read that trac ticket symbols defined in ntl change depending on the version 
of gcc. It is all about how you deal with c++ templates by default. The options
you are using are no doubt part f the mix. Although graphite is unlikely to
be the problem here, more likely lto.

You could try to emerge singular with CXXFLAGS=-fimplicit-template
not sure that will work without a patch.
