Re: [sage-support] Re: solving a linear system of GF(3) -- strange TypeError

2019-10-09 Thread Dima Pasechnik 
This is now https://trac.sagemath.org/ticket/28586

It would be great not to have to do git bisect on this, anyone can point
out to a suspect ticket?
Thanks!

 So the full problematic code is

 B.solve_right(v)

 Is there some hidden limitation of sparse matrices over finite fields?

Re: [sage-support] SageMath installation in macOS Catalina

2019-10-09 Thread George 
Hi,

I tried Sage 8.8 (the app) following Tom's comment and it seems to work 
(thanks Tom). 

I'll try building from source and see how it goes. 

Thanks a lot for your responses. 

Any additional updates/news are very welcome in case others are facing 
similar problems. 

Thanks,
G

On a recent beta release of Catalina, I used homebrew to install gfortran, 
and it went fine, allowing me to build Sage from scratch. I haven't yet 
tried with the actual release of Catalina, but I will soon.

[sage-support] SageMath installation in macOS Catalina

2019-10-09 Thread George 
Hi,

I upgraded to the new macOS Catalina and SageMath won't install. I get 
errors like "python2.7 cannot be opened because the developer cannot be 
verified" and for numerous other components as well. 

Is anyone having the same problem? Any tips, advice or ideas on what is 
going on and how to fix this?

Thanks a lot,
G
