Cython HowTo

How to Update Cython in FEMhub

Use these instructions if your FEMhub installation failed with an error "Cython too old".

Go to the directory where you have all your repositories (such as /home/pavel/repos/). Then do:

git clone https://github.com/cython/cython.git
cd cython
femhub --shell
python setup.py install

If femhub is not found, then you need to add the path to your local femhub directory to your PATH variable in the .bashrc file:

export PATH=${PATH}:/home/pavel/repos/femhub/

How to Update Cython on your computer (outside of FEMhub)

git clone https://github.com/cython/cython.git
cd cython
python setup.py install --home=~/usr

Add the path to cython to your PATH and PYTHONPATH in the .bashrc file:

export PYTHONPATH=.:$HOME/usr/lib/python:$PYTHONPATH
export PATH=.:$HOME/usr/bin:$PATH
