hearot / primecount-python

A Python wrapper for primecount.

hearot

✨ よ！ ✨

I'm Gabriel, but you can call me hearot. This username has no real meaning, since plenty of people have asked me (nay, it does not come from beowulf either); it's just a random name I made up when I was a kid. I live near Florence, Italy.

I study Mathematics at the University of Pisa. I enjoy playing some videogames, but I wouldn't call myself a gamer. I'm a big fan of Formula 1 and Ferrari, by the way.

I'm an old fan of Telegram, which explains why I'm using it all the time. You can text me there! In fact, my first script was a Telegram bot that I wrote in PHP. Then, I fell in love with Python!

primecount-python's Issues

libprimecount.so.6: cannot open shared object file: No such file or directory

Hi. When I try to perform the installation on a linux machine using your instruction, and then import the primecount in python, I get an error:
>>> import primecount
libprimecount.so.6: cannot open shared object file: No such file or directory

primecount works fine from the console though:
$ primecount 100
25

I read the https://github.com/kimwalisch/primecount/blob/master/doc/BUILD.md and tried to perform installation differently, with no luck:
sudo cmake . -DBUILD_SHARED_LIBS=OFF -DBUILD_STATIC_LIBS=ON (default)
sudo make -j
sudo make instal

and also
sudo cmake . -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=ON (recommended here)

and also...
sudo cmake . -DBUILD_SHARED_LIBS=ON -DBUILD_STATIC_LIBS=OFF

I see the libprimecount.so.6 symlink, so I don't know what's the problem...

I also tried adding /usr/local/lib/ folder to the dynamic libraries environment variable, with no effect:
os.environ["LD_LIBRARY_PATH"] = os.environ.get("LD_LIBRARY_PATH", "") + ":/usr/local/lib/"
or simply:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/

For now I resorted to a barbaric:
int(subprocess.check_output(['primecount', str(n)]).decode())

Please, help me out!

PyPI: source and additional wheels

This library was very useful for me - thanks for making it!

I noticed that the only distributions on PyPI are for CPython 3.6.

It would be great if you could publish wheels for the other supported versions of Python (currently 3.6, 3.7, 3.8, and 3.9) as well as a source package.

Please rename repo to primecount-python

Hi Gabriel,

Could you please rename this repo to primecount-python? It will be easier to find your repo using Google and it will also be easier for myself to create a bindings section in primecount's README.md which lists all bindings. Note that the pypi project name does not need to be renamed, it is nice if users can install it using pip install primecount.

Thanks,
Kim
