Error building python3-3.12.5

[robin....@web.de]

Hey I was trying to install/get started with sage.
When I run make, I get the following Error:
Error building python3-3.12.5

Went into the log to see Error and it said to post it here.

Not sure if it matters, but I was trying to installed sage earlier with make, then interrupted it (with keyboard interrupt) to apply the .highly /configure option 

11. Optional but highly recommended ...
export  MAKEFLAGS="-j$(nproc) -l$(nproc).5"

from the readme.md (https://github.com/sagemath/sage/blob/develop/README.md)

so it does not take ages to install sage,

After I did this I ran make again and then got this error.

There is no need to build Sage's Python, an external Python will always do.

(We have at last agreed that this mostly broken capability of Sage, to build its own Python,

should be removed, as it mostly leads to such annoyances)

 

I suggest to install enough system packages, as suggested by the ./configure, or as described in this link:
