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
configurable options:
---------------------
ASSERT_LEVEL_WANTED=1 (default)
SECURITY_LEVEL_WANTED=0 (default)
APSERVER_PATH=/tmp/GNU-APL/APserver (default)
APSERVER_PORT=16366 (default)
APSERVER_TRANSPORT=0 (default)
CORE_COUNT_WANTED=8
DYNAMIC_LOG_WANTED=no (default)
MAX_RANK_WANTED=8 (default)
RATIONAL_NUMBERS_WANTED=yes
SHORT_VALUE_LENGTH_WANTED=12, therefore:
sizeof(Value) : 464 bytes
sizeof(Cell) : 24 bytes
sizeof(Value header): 176 bytes
VALUE_CHECK_WANTED=no (default)
VALUE_HISTORY_WANTED=no (default)
VF_TRACING_WANTED=no (default)
VISIBLE_MARKERS_WANTED=no (default)
how ./configure was (probably) called:
--------------------------------------
./configure '--with-ctrld_del=yes' 'RATIONAL_NUMBERS_WANTED=yes'
'CORE_COUNT_WANTED=8'
