cython test

Learning basic Cython

Test for lean cython with blender.

Install dependencies:

$ pip install cython

To see which files are most worth optimizing:

$ python3 -m cProfile -s time main.py

$ sudo apt install build-essential python3-dev

You must have installed in your system the same python version that uses blender, exactly the same.

In my Linux Mint 19.3 Tricia:

Download python 3.7.4

cd folder

$ sudo apt install zlib1g-dev libffi-dev libssl-dev

$ sudo apt purge pytho3-pip

$ ./configure --with-ssl

$ make -j 2

$ sudo make install

$ sudo chown $USER:$USER -R $HOME/.cache

Note: in pycharm put existent enviroment: /your/path/Python-3.7.4/Python/

For compile on the fly:

$ cythonize --inplace --annotate archivo.py

Normal Compilation:

$ python3 setup.py build_ext --inplace

In Unix use ".so" files, in windows ".pyd", these files are imported into your normal python code.

For compile in Windows 10:

You need "MS Windows SDK for Windows 7 and .NET Framework 4", and "Visual Studio Build Tools 2019". then open the Developer Command Pront vor VS 2019 and compile from there. It is not recommended to use MinGW.

Automatic convert .pyx to .so compiled (Because writing a setup.py each time is painful):

$ sudo pip3 install easycython

$ easycython voronoi.pyx
