[ros-users] Cross-compiling TF --> Bullet

[Brian Gerkey]

hi Daniel,

Cross-compilation is not a well-exercised feature of ROS, so I'm not
surprised that you're running into some trouble.  The 3rdparty
packages (e.g., bullet) are the most likely to be problems.  We'd
happily accept patches that makes those packages cross-compile
correctly.

	brian.
