[sage-devel] Should ZZ^2 be a submodule of CC^2?

Dear all, I am working on ticket #23978 Rich comparison for Modules As part of it I also rewrote the is_submodule function. Currently, we have sage: (ZZ^2).is_submodule(CC^2) False sage: (ZZ^2).is_submodule(QQ^2) True Should that behavior change

Not sure which file you mean..? There seems to be no configure file just for mpfr, I've attached the generated config files I'm off for a few days as of thsi evening, but will be very grateful for any suggestions when I get back! Regards, Maria On Thursday, 18 January 2018 10:57:10 UTC, Dima

Hello, thank you for everyone's interest. There are a few who are willing to mentor again, but we also need short outlines of potential summer projects. So far, there is just one here: https://wiki.sagemath.org/GSoC/2018 for comparison, and maybe also as a source of inspiration, last year is

It will help to see the config.log of mpfr (not sure whether current mpfr is known to run on Sparc Solaris...) On Thursday, January 18, 2018 at 10:49:22 AM UTC, Maria MacCallum wrote: > > > Could you help me debug the errors? > > Last successfull install of sage that I know here is 6.2 > > > > >

Re: [sage-devel] Error installing package mpfr-3.1.5.p0

Actually given the error it may be a good idea to try gmp instead of mpir to start with. gmp may have better support for sparc than mpir. So before starting the build you should do ./configure —with-mp=amp and then make as you usually do. François > On 18/01/2018, at 23:49, 'Maria MacCallum'
