Hello all,

I am trying to install the point cloud library (http://www.ros.org/wiki/pcl) as a stand-alone application, on OSX 10.6.4. However, during the installation process, eigen3 is the only dependency that it fails to find.

I 'installed' eigen3 using the instructions in the INSTALL file, using cmake to build eigen3 in a 'build' directory in the source folder. Is there anything else I need to do to get it to be recognized by the PCL installation? Do I need to add a path to eigen3 in my bash_profile, or install it somewhere specific on my system?

I realise the answer may be PCL related, but I haven't found anything useful in that direction yet.

Thanks for any help,

Bill

Did you run 'make install' ?

Where did it install to? (As the cmake output tells you, you can change that to your liking with -DCMAKE_INSTALL_PREFIX=...)

From there on, it's up to PCL's build system to find Eigen3. We provide a cmake module for that purpose, cmake/FindEigen3.cmake.

And use latest SVN eigen, as beta-2 is too old for PCL.
