Just for a heads up. This all worked great. I did scratch my head on some installs I needed for a fresh Ubuntu install. Most are things that are listed in the other post. This one had me scratching my head when I built the WPILIB.
There is a program in a batch file that took me a minute to find that I needed. Once I read the error message and went through the batch script it became obvious.
export WIND_BASE=$(realpath "$WIND_BASE")
realpath had to be apt-get installed.
Then there is replacing /path/to
/home/paul but that is because I am stupid.
Thanks for the hard work.
