Error installing from source in Ubuntu 16.04 LTS
George Christodoulides
I am trying to build Pupil from source, following the instructions found at https://docs.pupil-labs.com/#linux-dependencies.
When attempting to install pyuvc (using the command sudo pip3
install git+https://github.com/pupil-labs/pyuvc), I am getting a
linking error with libturbojpeg (see output below).
Has anybody encountered this error before? Any ideas on how to fix it?
Thank you,
George Christodoulides
