Problem 1

Upon Step 9 (running source ~/.bashrc) I got:

sh: /vagrant/operator/devel/setup.bash: No such file or directory

Solution

Had to cd to operator and run catkin_make. Added this to base-install.sh.

Problem 2

gscam not found

Sometimes git submodules don't install after running the install script. For instance, gscam might not be able to find videofile.launch; this would imply that the gscam submodule was not installed.

Solution

If /vagrant/operator/src/gscam is empty, it means the gscam submodule wasn't installed. To install, go to the folder and enter:

git submodule update --init --recursive

Problem 3

cannot launch node of type [gscam/gscam]: can't locate node [gscam] in package [gscam]

If you ran into the missing git submodule issue above, you might need to run catkin_make again:

cd /vagrant/operator
catkin_make
source devel/setup.bash

Problem 4

Running into issues playing a video.

First: gscam relies on gstreamer. See if this plays a video:

gst-launch-0.10 filesrc location=/path/to/video ! decodebin ! ffmpegcolorspace ! ximagesink

If that works, not sure what the fuck to do next.
