Error in installation of latte_int [Sage 8.4, MacOS 10.14.5, Xcode 10.2.1]

[Marco Castronovo]

Dear all,

I tried to install LattE on Sage using "sage -i latte_int", and it stopped while installing the package latte_int-1.7.3. The error I get is:

[latte_int-1.7.3] buildPolytopes/BuildPolytope.cpp:728:20: error: ordered comparison between pointer and zero ('__mpz_struct *' and 'int')

[latte_int-1.7.3]         assert(currentLCM > 0);

[latte_int-1.7.3] 1 error generated.

Please find attached a more detailed log. I'm using SageMath 8.4 (release date 2018-10-17), CPU 1.6 GHz Inter Core i5, MacOS Mojave 10.14.5 with Xcode 10.2.1.

Best regards,

This is fixed in more recent versions of Sage, which include LattE 1.7.5. https://trac.sagemath.org/ticket/26190

Thank you! I upgraded to Sage 8.6, relaunched "sage -i latte_int" and it correctly installed latte_int-1.7.5.
