I am trying to install Electron Direct Methods (edm: http://www.numis.northwestern.edu/edm/) code on Ubuntu 14.04 LTS 64-bit, standard install. This requires a standard configure - make - make install routine, which worked well on Ubuntu 12.04 64-bit. However, configure fails on the present 14.04 system with the following message:
checking for X... no I cannot find a working X Window System You may need to set --x-includes=dir and --x-libraries=dir Giving up........sorry
What gives? I thought all Linux systems including Ubuntu use X11. On this system, X in /etc/X11 points to /usr/bin/Xorg and /usr/lib/xorg has just one modules directory. Is X to be specifically installed, or are there other directories to point --x-includes and --x-libraries to?
