I am working on it right now … My problem is python_orocos_kdl is looking for eigen and I can't load it from macports due to a checksum miss match. Googling around, it appears that author likes to do stealth updates and I can't seem to figure out how to force macports to install eigen. Did you have this problem?

I fixed the cmake problems with orocos_kdl, similar to you, but I get a ton of undefined symbol link errors for the python version, which prevents many stacks from building. It is a huge point of failure for me right now. > > > > On Sep 3, 2011, at 10:22 AM, Kevin Walchko wrote: > >> Hi, >> >> [setup] >> >> ROS Electric >> OSX Lion with Macports >> >> [Problem] >> >> Eigen3.cmake couldn't find eigen3 >> >> [Solution] >> >> Instead of using the included cmake files in orocos_kdl/config/Eigen3.cmake I changed CMakeLists.txt to use pkg-config which macports automatically sets up for OSX.
