Brian,
I have installed C Turtle and included the lines John gave in the
manifest.xml of package "opende," though they did not seem to have any
effect.
Attached are the build_output.log files for atrias_sim on the first and
second Make invocations.
Do you think using third-party dependencies will be a dead end in the long
run? I will soon try using the system installation of ODE instead of the one
provided by ROS since the system-wide ODE installation currently compiles
with our non-ROS code.
