No python script 'integral.py' in the current directory or in
/usr/local/bin
What should the 'integral.py' script contain, and is it
auto-generated by GNU APL during build, or is it supposed to be
installed by the Python 'sympy' package?
It is not present in my setup.
I see, after building GNU APL, there is a zero-byte 'integral.py'
file in src/ and I see the Makefile just uses 'touch' to create that.

Hi,
I am not really a python expert, but trying my best.
On my box I have installed python and sympy and it works.
I therefore suppose your problem is related to your installation.
Having that said, could you please send me the the
*)MORE* information right after the *DOMAIN ERROR*?
Other things to check:
*⎕ENV* in apl, in particular *PYTHONHOME* and friends.
BTW python is checked at runtime therefore the *,/configure* output
does not matter,
Thanks,
Jürgen

Hello,
In regards to the new ⌹.integral support -- I am seeing the
DOMAIN ERROR as mentioned in docs
(https://www.gnu.org/software/apl/apl.html#Integral-B), yet I
have installed python sympy package.
It is locally installed, in $HOME/.local/bin as both 'sympy' and
'isympy' on my system.
I ensured $HOME/.local/bin was in my $PATH prior to running the
newly-installed GNU APL, and can run 'sympy' from there by
itself from bash to evaluate expressions.
My system has Python 3.9.20, installed as /usr/bin/python3 ->
python-exec2c
Is there any additional config or debug I should enable to
troubleshoot this failure to find sympy?
$ apl --cfg

Hi,
as a late Xmas present, there is a new GNU APL function
*⌹.integral* which,
nomen est omen, computes the indefinite integral of an
expression *B*:
* 2 ⌹.integral "sqrt(x³)"
_____
2⋅x⋅╲╱ x³
───────────
5
*
*SVN 1937.*
Enjoy.
Jürgen
