I think it might be related to Mac having an old version of makeinfo. I see from your config.log that you use homebrew. To get ECL to build you can try brew install texinfo export PATH="/usr/local/opt/texinfo/bin:$PATH" and then rerunning configure and make. I haven't tested with sage, but

Looks like a missing makeinfo problem. I thought we had a fix for that included. But I only poorly followed the ecl upgrade ticket due to other commitments. > On 19/07/2020, at 12:50 PM, David Einstein wrote: > > Attempting to rebuild sage I run into problems building ecl. This baffles > me,

2020-07-18 Thread John H Palmieri
Can you give a specific example of a computation in which you care about the degree where your zero element lives? Or where you can't just recover it from its component elements (if ab=0, then you have an element in degree = deg(a) + deg(b)). I'm struggling to understand this. If you are doing

Hi Sverre, I don't think it's a good idea to have different zeroes in an algebraic structure that is also categorized as an abelian group, unless you take the point that a "graded abelian group" should not be an "abelian group". But let me also point out that something similar to what you

Hi, Thank you for your comments so far. I feel I need to expand some more on the issue of zero elements which is the central thing for the problem we are adressing. It is mathematically equivalent to think of a graded k-algebra A as either 1) a direct sum A = \bigosum_i A_i, together with a

Hi Sverre, I ran into similar problems in my "yacop" package (https://github.com/cnassau/yacop-sage), which also deals with graded modules over the Steenrod algebra. I think when I began, Sage didn't even have its own category of graded things, so I ended up inventing my own category of
