Hi, I tried to compile mrpt 0.95 on ubuntu lucid, but the following errors appreared.
How to fix?
BTW, is the binaries on Ubuntu PPA repositories comipled with PCL?

Hi,
That's because of an update in the ffmpeg libraries. The latest version of MRPT (from SVN trunk) fixes it. Try with that new version, or at least replace the .cpp file that fails. I'll soon release 0.9.6, but it may take at least 2-3 weeks but in the meanwhile there's no easier solution.
On PCL, nope, it's not included in PPA. But notice that you can use most of the MRPT-PCL integration by just including PCL headers in your code as well as including MRPT's. See this list: http://reference.mrpt.org/svn/dep-pcl.html and the examples of MRPT-PCL integration: http://mrpt.googlecode.com/svn/trunk/doc/mrpt-pcl-examples/
