Dear Kim,
As mentioned on the ticket, this big-endian incompatibility does not
prevent the inclusion of primecount as an "experimental package" that I
still aim to achieve (the type of the package "experimental", "optional"
or "standard" is simply a flag). In practice "experimental" means "not
officially supported" and "less tested".
And as Dima mentioned, it would be simpler for SageMath to have
primecount supporting big-endian. We certainly do not want that a single
library prevents using SageMath on big-endian architecture.
Now, three questions for Sage developers:
- Who is testing a big-endian architecture?
- Are all optional packages big-endian compatible?
- Is it reasonable to ask for big-endian compatibility for
optional packages?

PS: to discuss these kind of issues related to development, it is better
to use the other google group sage-devel.

Hi,
We all know that the big-endian CPU architecture is slowly dying,
some people even state that "Big-Endian is effectively dead".
So my question is: Does sagemath still support big-endian CPU
architectures like e.g. 32-bit Sparc?
We have recently more or less revived a SPARC Solaris 11 port of Sagemath.
So yes, please, make it both-endian...
I am asking because there is a ticket
(https://trac.sagemath.org/ticket/24966
<https://www.google.com/url?q=https%3A%2F%2Ftrac.sagemath.org%2Fticket%2F24966&sa=D&sntz=1&usg=AFQjCNHvco5SWFB7CiS50MxgtC2P8g3mxA>)
to integrate my primecount
library into sagemath and primecount currently only supports
little-endian CPUs. I could support big-endian CPUs but I want to
make sure this is required by sagemath.
Thanks,
Kim
