[sage-devel] Is anyone trying to build Sage on old x86 without MMX?

2015-05-20 Thread Jean-Pierre Flori
In http://trac.sagemath.org/ticket/18027, Jeroen would like to drop (partly) drop suppor for such CPUs when signals are received. I guess what would happen is that an additional SIGILL or something like that will happen because of the unsupported MMX-only FPU reset asm instruciton, but I did

+1 MMX is now 19 years old, its unlikely that you can build Sage on such an old CPU. We certainly have no way of testing. On Wednesday, May 20, 2015 at 9:28:25 AM UTC+2, Jean-Pierre Flori wrote: In http://trac.sagemath.org/ticket/18027, Jeroen would like to drop (partly) drop suppor for

Hi! Several people reported that they cannot build my group cohomology spkg, apparently since Cython creates code that attempts to include ccobject.h, which does not exist. It gives rise to the following questions: 1. Why does Cython request ccobject.h? ccobject is not mentioned in my code!
