I've added build instructions to install it into the sagemath 7.3 environment. This of course doesn't solve the import issue. I.e. this needs some upstream reporting!

sage: from polymake import *

When is gcc 6 planned to be installed? In my machine (on which it compiles) I have 6.2.1 installed. It seems that it's complaining about cxx11, and maybe it's related to the switch to C++11?

[haraldschilly]

There are no plans for gcc6, just a plan to switch to a new compute environment, which is based on ubunteu 16.04. I don't know if that has gcc 6.

[haraldschilly]

there seems to be a gcc-6 package for ubuntu 16.04, which conflicts with the version 4, but the default is gcc 5. so, maybe that can be installed, but I'm not sure what it really contains -- there doesn't seem to be that much support so far.

over at videlec/pypolymake#12, @videlec asked for the full logs after running:

$ sage -f polymake
$ sage -pip install git+https://github.com/videlec/pypolymake

Ubuntu 18.04 ships gcc 7.3.0, so the upgrade to Ubuntu 18.04
should allow this issue to go forward. While we are at it, it would
be nice to replace Polymake 3.0 (currently in CoCalc) with the
latest Polymake, which at this time is Polymake 3.2r2.

Please also install the Polymake Jupyter kernel:

Reported by Ahmed:

This breaks in current sagews:

%default_mode polymake
--- new cell
application 'tropical';

[jdchristensen]

It appears that polymake is an optional sage package and that the binary is installed in CoCalc. It works from the command line, but not within a sage worksheet. If I type

polymake.cell24()

I get a long backtrace. The important part shows that /usr/bin/env TERM=dumb polymake is being run, and that does indeed lead to an error if run in the terminal:

Can't locate object method "new" via package "Term::ReadLine::Gnu" at (eval 141) line 4.

If I try

p = sage.interfaces.polymake.PolymakeExpect(command='/usr/bin/env TERM=vt100 polymake')

there is no error, but it doesn't return. I suspect that what is happening is that Sage doesn't recognize the prompt because it is surrounded by bold escape sequences.

Any suggestions? Should I open a separate issue?
