can't compile on Ubuntu 16.04 fresh install

[mcamurri]

I'm having an issue compiling the repository on a new machine:

~/legacy_pods/libbot/bot2-vis/pod-build/lib/libbot2-vis.so: error: undefined reference to 'XOpenDisplay'
~/legacy_pods/libbot/bot2-vis/pod-build/lib/libbot2-vis.so: error: undefined reference to 'XFree'
~/legacy_pods/libbot/bot2-vis/pod-build/lib/libbot2-vis.so: error: undefined reference to 'XVisualIDFromVisual'
~/legacy_pods/libbot/bot2-vis/pod-build/lib/libbot2-vis.so: error: undefined reference to 'XGetVisualInfo'

Is there a missing dependency? I couldn't find a README with pre-requisites.

Note that I've commented out the tobuild.txt of the repo to include only as follows:

• bot_core_lcmtypes
• libbot
• occ-map
• common_utils

and the common_utils to include only:

• concise-args
• stl-utils
• path-util
• eigen-utils

This works on another machine I've already set up.

i cant reply now, but does this help:
https://github.com/ashuang/libbot
https://github.com/libbot2/libbot2
its the upstream source of libbot

I've solved the problem by explicitly adding X11 to the target libraries.

Note: the commit of libbot this repo is pointing to is pretty old. It does not include my previous bugfix.

I've created a merge request on top of libbot-openhumanoids and not mf-revert-double-pane-on-gtk-viewer as it is pointing right now.

This change has to be coupled with its counterpart in common_utils.
