Dear Tiago, while trying to compile graph-tool for anaconda3 and python 3 we came across following error message: configure: error: pycairo headers not found I ran the following command: ./configure --with-boost=/usr/local/anaconda3 --enable-openmp Python3 is installed in /usr/local/anaconda3/bin and typing in python starts the correct version. The pycairo headers (py3cairo.h) are located in: /usr/local/anaconda3/include/pycairo I am surprised it can't pick the file up, because it seems to pick up other files from /usr/local/anaconda3/include. Do you have any idea what we could have missed? The config.log <http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/file/t496114/config.log> is attached and I am running Ubuntu 16.04. Many thanks, Jana -- Sent from: http://main-discussion-list-for-the-graph-tool-project.982480.n3.nabble.com/
