Since you did not provide the full source code, I can only make educated guesses from the error message itself. Boost::

catkin_make fails, looking for -lBoost::system I am trying to run catkin make on a repo that I got from my schools githu

I'm not sure what you're trying to accomplish. The LaserScan message contains only ranges, which are always relative to

You forgot the placeholder _1 for the argument that will be passed to your callback

It will probably work for x86_64, but not for i386, because static 32 bit libraries are usually not compiled with -fPIC

Since I upgraded to Groovy, the rospack command has become really slow. This is true even if have no own package tree, just the distribution itself. The rospack profile call runs fast and shows nothing abnormal, but any query takes over a second. Any ideas what is wrong?

I installed Groovy and created a brand-new catkin workspace according to this tutorial, and everything works fine so far. However, I tried to overlay my old rosbuild-style (aka "dry") packages like this:

source $HOME/ros-groovy/devel/setup.bash
mkdir $HOME/ros-groovy-old
cd $HOME/ros-groovy-old
rosws init . /opt/ros/groovy
rosws set $HOME/path/to/my/packages

According to REP-128, I can enable the overlay with source $HOME/ros-groovy-old/setup.bash. This lets me work with my dry packages, but it makes ROS forget about my catkin workspace. If I re-source $HOME/ros-groovy/devel/setup.bash, I can use my wet packages in the catkin workspace again, but I loose the dry packages in the rosbuild workspace.

I checked and it seems that both setup.bash overwrite the ROS_PACKAGE_PATH with their own values. But how can I make them aware of each other? The only documentation Google came up with told me that the overlay should Just Work(tm). What am I doing wrong?

I have a publisher with a high data rate (approx. 100 Hz) and multiple subscribers. One of them requires the full data rate, while another is quite happy with one message per second.

My simple solution for the latter is to process every 100th message only, but I was wondering if ROS provides a more elegant solution, such as a message filter or a subscription option which lets me choose the desired message rate.

I have exactly the same problem as described in this question, i.e. the rviz interface does not show up if I start roscore and "rosrun rviz rviz".

I have installed the latest ros-diamondback-* packages from the official repository (version 1.4.1-s1308330112~natty). I tried several different window managers including GNOME, Unity, and KDE Plasma. I tried four different computers with Natty, and the most disturbing part is that it works on exactly one machine (with KDE), but for no apparent reason; it is the same hardware (HP Z800 workstation).

I have successfully run Gazebo with Ogre and glxgears, so there is no obvious problem with my 3D acceleration (NVIDIA). There are no helpful error messages in the logs. There are a few warnings and errors, but they show up on the working machine as well.

How you design your classes is up to you. However, I recommend the ConstPtr variant in all cases, because passing shared pointers allows ROS to bypass serialization and use shared memory message transport in nodelets.
