Hi, I'm wondering what the version of PCL library in my ROS is. For example, currently PCL is 1.5.1 updated on 2012.02.22, then what is it for my PCL? And where can I check out these version information? Also, how can I update my PCL in ROS when the standalone PCL library is updated?

Thanks for answering.

The general policy is for each ROS distribution to depend on the most recent PCL library available at the time it is released. For API stability, that will remain fixed until the next release.

Since PCL changes faster than ROS, that library version will not remain the latest for long. If it gets far enough behind, an unstable PCL may be published for those needing new features and not requiring API stability.

Beginning in Fuerte, ROS uses rosdep for the system PCL. That should make it easier to use newer versions as they come out.

Hi, is it correct to check out the version information by sudo apt-cache policy ros-electric-perception-pcl? Thanks!

That should work. Mine says 1.0.2 for Electric right now. If you need something more recent, see answer from @karthik.

Thanks. Mine says 1.0.2 and I'm using Electric, too. But at this page http://ros.org/wiki/electric it states that PCL in Electric is v1.1, thus I'm wondering which one make sense.

Mine one is also 1.0.2. Maybe, it also depends on ubuntu version, I'm on Lucid anyway..
