Trying to build Python 3.12 on Termux

[craigmj]

Hi,
I'm trying to build Python 3.12 on Termux. I've downloaded the sources from python.org, run ./configure but on make I get an error:

Python/fileutils.c:2912:9: error: call to undeclared function 'close_range'; ISO C99 and later do not
      support implicit function declarations [-Wimplicit-function-declaration]
 2912 |     if (close_range(first, last, 0) == 0) {

I'm working on a Samsung Galaxy Tab 10, so the ANDROID_API_LEVEL is 36, but pyconfig.h sets the level to 30, but even changing that in pyconfig.h doesn't help.

Is anyone able to shed some light on how I can go about building python (and other systems, which are also giving me trouble) on Termux?

Best,
Craig
