Hello there,

I have been attempting to complete the tutorial (I can't publish links! Simply google "ros compile nao virtual" and click the 1st result) which attempts to compile ROS to a virtual Nao, before copying the files across to the actual robot.

There have been a number of problems throughout the process, however it is of my understanding that these have been dealt with successfully. I have followed the Wiki as closely as possible.

I am using VirtualBox Graphical User Interface Version 4.2.10_Ubuntu r84101.

The OpenNao image is "opennao-vm-2.0.1.54.ova"

I have managed to "emerge" all packages mentioned in the Wiki. I decided to add "Boost" as well. Problems have arisen when attempting to compile the packages, using the command:

$ src/catkin/bin/catkin_make_isolated --install -DCMAKE_BUILD_TYPE=Release

This attempts to compile 81 separate packages - I can only make it as far as the 37th package before I get an error, specifically (I have to type all of this since my VM won't allow me to cut & paste: please excuse any spelling errors!)

Command failed, exiting.

Of course, this is only stage 37 of 81, so I assume fixing this error could open up more. Either way, any suggestions would be greatly appreciated.
