Lost while trying to compile Python 3.11.1

This seems to cure the ncurses problem:

edit setup.py to read:
curses_includes.append('/usr/local/include/ncursesw')

This seems to cure the ncurses problem:

edit setup.py to read:
curses_includes.append('/usr/local/include/ncursesw')

I forgot to mention this was already done since the beginning.

But anyway I kinda redneck my way through compilation (after many many tries) of Python 3.11.1...

To successfully compile it I needed to ditch the CFLAGS/CXXFLAGS flags.

This is the step I did:

- Extract source files
- edit setup.py to change curses_includes.append path to /usr/local/include/ncursesw
- ./configure --prefix=/usr/local --enable-shared --enable-optimizations <--- slower but worth it
- make -j -l 4
- make altinstall DESTDIR=/tmp/python3.11
- mksquashfs /tmp/python3.11 python3.11.tcz
- cp /tmp/python3.11.tcz /mnt/mmcblkp2/tce/optional

If I added the CFLAGS/CXXFLAGS flags, make will always fail afterward ... I tried many flags settings ... spend two days watching compilation fails

tce-load -i python3.11

all good now ,,, thanks!

I just tested on an RPi3 running piCore-13.1 and this works:

Code: [Select]

tce-load -i compiletc sqlite3-dev tk-dev glib2-dev gdbm-dev libEGL-dev readline-dev liblzma-dev openssl-dev

wget https://www.python.org/ftp/python/3.11.1/Python-3.11.1.tar.xz
tar xf *tar*
cd Python-3.11.1

edit setup.py
curses_includes.append('/usr/local/include/ncursesw')
