Hello,
I just verified that
sudo make install
does indeed put integral.py in my /usr/local/bin, with execute perms.
I must still have something wrong with my Python setup, though:
$ echo "2 sqrt(x³)" | python3 /usr/local/bin/integral.py
<→WRAPPER-STARTED→>.
<→MODULES-IMPORTED→>.
Traceback (most recent call last):
File "/usr/local/bin/integral.py", line 133, in <module>
expr = input_filter(input())
EOFError: EOF when reading a line
$ python3 --version
Python 3.9.2
