so your compiler (gcc-5.4.0) broke down at this stage but it will be difficult to know why.
You are compiling directly on the pi?

Yes, I'm compiling on the pi.

OK so asking for sage to install its own gcc may be overkill as I am expecting it
will take forever. Do you have access to another compiler - gcc or clang-5+?

I figured, so I installed gcc, g++ and gfortran from the ubuntu packages as in http://doc.sagemath.org/html/en/installation/source.html#prerequisites.

Did this ever work? I don't think a RaspPi even has enough memory to
compile some of Sage's dependencies, especially some of the C++ heavy
ones.

1GB (the current model) + swap ought to handle this, albeit slowly

Something like https://www.pine64.org/?product=rock64-media-board-computer (with up to 4GB RAM, basically
the same form factor)
looks much more reasonable...

The compilation process hasn't had a problem with running out of memory so far, and I'm not so concerned with how long it takes.

How do I figure out why this package is failing to build? I ran make -k and it took ~16 hours, but fflas_ffpack was the only error.

naturally, nothing that depends on this package has been built, either.

You're getting

In file included from ffpack_inst.C:68:0: 
ffpack_inst_implem.inl:396:1: internal compiler error: in get_untransformed_body, at cgraph.c:3263

which are hard to deal with. Probably building it with -O0 rather than with -O2 might help.
Namely, edit line 14 of build/pkgs/fflas_ffpack/spkg-install,
which sets CXXFLAGS, and change there O2 to O0

Upgrading to gcc-6, g++-6 and gfortran-6 from the ubuntu toolchain ppa and adding some swap made 'make build' work. There's still some error with building the documentation, but that's a separate issue.

Thanks for reporting this! I updated the "Exotic ports" page on
our Trac wiki:

Building docs is at present very RAM-hungry. But you only really need it is you hack on Sage, otherwise doc.sagemath.org has everything doc-building builds.
