[ros-users] Enabling double precision and finding libraries in ODE

Hi Brian,

As for the differences between the two runs, it's just warnings.  On

As I described in my reply to John, it looks as if the changes to the cflags
and lflags made in manifest.xml are not taking effect.

It sounds like the ODE included in ROS is essentially there to guarantee
compatibility and reliability. I will then try to stick with it.
