Error building Sage.

The following package(s) may have failed to build (not necessarily

I've attached the file '/opt/sage/logs/pkgs/fflas_ffpack-2.2.2.p0.log'. What do I need to fix?

The real interesting bit is

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.

[François Bissey]

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+?

[Ronno Das]

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.

Did this ever work?  I don't think a RaspPi even has enough memory to

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...

[Ronno Das]

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.

[Ronno Das]

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:

[Dima Pasechnik]

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.
