[sage-devel] Re: Can I build Sage via MacPorts under MacOS 10.9?

[John H Palmieri]

In principle this should work. See 
https://github.com/sagemath/sage/issues/31505 for some relevant 
information. Others might have direct experience with it.

[sage-devel] Can I build Sage via MacPorts under MacOS 10.9?

[Louis Deaett]

I'm interested in Sage development (and contributing some enhancements) and 
so I'd like to be able to build the current release (and ultimately the 
development branch) from source.

I am running macOS 10.9 (Mavericks) because that is what I prefer, and 
because some of my hardware tops out at that version.  Anyway, I've had 
decent success getting open-source software up and running under MacPorts, 
which has good support for 10.9 (and even earlier).

So I've been working on building Sage from source using MacPorts. 
 Compilation seems to go smoothly with MacPorts LLVM tools, but I've run 
into some snags whereby the build for some SPKGs seems to get gummed up 
when it can't locate some of the libraries or headers provided by 
MacPorts.  By its nature, this hasn't felt like an insurmountable problem.

Still, while I can keep hacking away at this, I figured I should ask:  Is 
there any fundamental reason why what I'm trying to do should be impossible?

If there are major barriers in my path with this that I'm just not 
encountering yet or just haven't realized, then it would (of course) help 
me out to know.

For what it's worth, if building under MacPorts is theoretically possible 
but would require some additional effort on the Sage side, then that's 
something I'd be willing to contribute to, if anything comes out of my own 
efforts.

Thanks in advance for any advice!

Re: [sage-devel] What was/is/will be the purpose of maintaining the Sage distribution?

[sumaiya qureshi]

Hey All!

Please let me know I am included within the accepted organization or not?

According to Karachi, Pakistan timezone last night was my GSoC'23 result.

Please guide me through the procedure how to check my GSoC'23 result.

Name :- Sumaiya Qureshi (Karachi, Pakistan)

I opted for Improvements to mathematics interaction with the desired
organization "Oppia" within Web category.

Let me know if you all sage developers want further information regarding
myself to search my result.

Regards,
Sumaiya.
