Problem with Cython while installing.

[specia...@gmail.com]

Hello Everyone,

I am trying to install plumed 2.5.0 on my local machine, so i launch ./configure --prefix=/opt , i Make, but during the installation i get this error:

plumed.cpp not found, cython is needed
importing cython
Error: building plumed requires cython. Please install it first with pip install cython
Makefile:247: recipe for target 'install' failed
make[2]: *** [install] Error 255
make[2]: Leaving directory '/home/carlo/Downloads/plumed-2.5.0/src/lib'
Makefile:11: recipe for target 'install' failed

So the first thing is that i actually have a plumed.cpp file in ./python when running "sudo make install", so i am not sure why the program doesn't find it. Secondly I have cython installed and "which cython" outputs /home/carlo/programs/anaconda2/bin/cython

I guess there's some problems with some internal references, but i don't know where. Can anyone help me fix this?

Best regards,
Carlo Martinotti

I think root user cannot see cython because it is installed locally.

Are you sure you want to install plumed as root but link it to a user installed anaconda?

You can disable python wrappers (with configure —disable-python) and, if you need them, install them separately with pip install —user plumed
