Compile pip-installable wheel on Ubuntu 20.10 [solved]

[fginter]

Just in case anyone needs this, this is how I compiled and installed simstring on Ubuntu 20.10. I am sure the pull request #26 is solving the same thing, but I did not notice it until it was too late. So for the record, this "worked for me" (tm)

1. make sure you have python-dev and swig installed from your package manager

./autogen.sh
./configure
make
cd swig/python
./prepare.sh --swig
pip3 install --upgrade pip setuptools wheel

Now replace setup.py with the version below and then you can:

python3 setup.py bdist_wheel

This gets you a wheel file under dist which you can pip-install as you wish

pip3 install /path/to/simstring/swig/python/dist/simstring.version.whl

Here is a test in python

>>> import simstring
>>> db=simstring.writer("test.db")
>>> db.insert("koira")
>>> db.insert("kissa")
>>> db.insert("autoni")
>>> db.insert("Åbo Akademi")
>>> db.close()
>>> db=simstring.reader("test.db")
>>> db.measure=simstring.cosine
>>> db.threshold=0.5
>>> db.lookup
>>> db.retrieve("Abo akademi")
('Åbo Akademi',)
>>> db.retrieve("auto")
('autoni',)
>>> db.close()

And here is the corrected setup.py:

#!/usr/bin/env python
