Re: compiling libapl for python3

[enztec]

Hi Jürgen

I'm using Python 3.10.7 for both and the svn it works with is 1533 and with svn 
1650 'import gnu_apl' gives the 'main' error

both of the compiled /usr/local/lib/apl/lib_gnu_apl.so are copied to 
/usr/local/lib/python3.10/lib-dynload/gnu_apl.cpython-310-x86_64-linux-gnu.so 

i didn't change or add anything in regards to the python3.10.7 installation 
from svn 1533 to svn 1650

if i copy the 1533 compiled lib_gnu_apl.so back to 
/usr/local/lib/python3.10/lib-dynload/gnu_apl.cpython-310-x86_64-linux-gnu.so 
the main error goes away   with 'import gnu_apl' and my python3 libapl code 
works perfectly

don't worry about it - i was just upgrading to 1648 and have some tests i run 
on a new svn installation - i don't do anything with python3 anyway and my apl 
ws and apl scripting code and libapl fpc code all runs fine
