Hi all, I'm wondering what's the status of the PCL stack under Osx Lion.

I read that there was some problems before. Currently I'm able to compile PCL from sources (not ROS stack), however when I try to compile the ROS stack it fails. In particular the first error is with Flann (see below). To be noticed that I'm using Homebrew as package manager. Why I need to recompile Flann and the ROS stacks don't reuse the HomeBrew version?

Thanks!

This is the rosmake perception-pcl --rosdep-install result:
