I've been struggling to get graph-tool installed on a standard 18.04 Ubuntu system for the past few hours (~5) due to the CGAL dependency. I first tried installing graph-tool from the packages, which ran fine but the library didn't actually seem to get installed (all the python import statements couldn't find it).
It most certainly got installed. If you can't import it, the most likely explanation is that you are not using the correct python interpreter. For example, sometimes people install python using anaconda, and expect it to find packages (such as graph-tool) which have been installed in the system, which will not happen. Sometimes people install a package for python 2, and cannot find it with version 3, etc.
I then tried installing from source and it makes it all the way to the end with the error:
checking whether CGAL is available in /usr... no checking whether CGAL is available in /usr/local... no checking whether CGAL is available in /opt... no checking whether CGAL is available in /opt/local... no
However, libcgal-dev is definitely installed:
dpkg -L libcgal-dev | head -n10 /. /usr /usr/lib /usr/lib/x86_64-linux-gnu /usr/lib/x86_64-linux-gnu/cmake /usr/lib/x86_64-linux-gnu/cmake/CGAL /usr/lib/x86_64-linux-gnu/cmake/CGAL/CGAL_Macros.cmake /usr/lib/x86_64-linux-gnu/cmake/CGAL/FindTBB.cmake /usr/lib/x86_64-linux-gnu/cmake/CGAL/CGAL_Common.cmake /usr/lib/x86_64-linux-gnu/cmake/CGAL/CGALExports-release.cmake
No amount of futzing about with the LDFLAGS/CFLAGS seems to get it to work.
The reason for the failure is usually to be seen in configure.log. Without this information, and how you evoked the configure script in the first place, with full output, is not possible to say anything.
Has anyone run into this before? This is probably the longest time I've spent trying to install a package in years :(
Which is ironic, given that your first try using the binary package probably worked just fine, you just didn't notice it. Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
