[ros-users] Errors compiling gmapping

[Vincent Rabaud]

That probably deserves some bug reports instead of a thread but I fixed the
redefined error in the ROS wrappers last week in SVN:
https://code.ros.org/svn/ros-pkg/stacks/slam_gmapping/trunk/gmapping/gmapping-r39-2.patch

gmapping compiles on gcc 4.7 now.

Not sure about your other error.
