compilation problem

Postby vdelecroix » 20 Jun 2017, 18:35

Hello,

I was trying to install polymake as a Sage package and ended up with the following compilation error
/usr/include/c++/7.1.1/limits:317:7: error: invalid abstract return type 'pm::graph::EdgeMapBase'
min() _GLIBCXX_USE_NOEXCEPT { return _Tp(); }
(I am using gcc 7.1.1). The downstream report for Sage as well as the complete traceback is available at

https://trac.sagemath.org/ticket/23289

Any help would be appreciated,
Vincent

Sorry, polymake can't be built with gcc 7 yet.
Please use clang or gcc 5/6.

Thanks. Too bad for me. Are there plans to allow gcc 7.1?

We are observing the same error messages and can't find our fault. Probably we've got to wait until gcc 7 matures a little bit more...

What about having a failure with an informative error message at configure step?

Please try the workaround in the attached patch (which is originally from the fedora polymake maintainers). Our testsuite just completed without any further errors (with gcc 7.1.0).

Oh, a nice surprise!

Actually, #ifdef is not needed here, the proposed variant for gcc7 should work for any other compiler as well.

Thanks! I posted a simplified patch at https://trac.sagemath.org/ticket/23289 for inclusion in SageMath.
