bfl on groovy, catkin_make errors and compile errors

I have a strange problem with using bfl under ros groovy. I'm using the regular installed bfl package. "roscd bfl" takes me to /opt/ros/groovy/share/bfl which contains a package.xml.

Yet when I include bfl in the find_package() line of my project's CMakeLists.txt just like any other ros package, catkin_make complains:

CMake Error at /opt/ros/groovy/share/catkin/cmake/catkinConfig.cmake:72 (find_package):
  Could not find a configuration file for package bfl.

  Set bfl_DIR to the directory containing a CMake configuration file for bfl.
  The file will have one of the following names:

  bflConfig.cmake
  bfl-config.cmake

If I leave out bfl from the find_package() and try to include e.g.

#include "bfl/pdf/gaussian.h"

the compiler throughs an excessive amount of errors (in total >700) e.g.

/opt/ros/groovy/include/bfl/wrappers/matrix/vector_wrapper.h:60: error: reference to 'MatrixWrapper' is ambiguous

Any suggestions, ideas what could cause that behaviour?

Found the problem, used Eigen in one of my classes and the Eigen namespace (Matrix type) collides with BFL. So removing

using namespace Eigen;

solved the >700 compile errors.

I have exactly the same issue, but I don't have any 'using namespace Eigen;' inside my code. However, I'm importing eigen into my CMakeLists.txt using this:

find_package(Eigen REQUIRED)
include_directories(${EIGEN_INCLUDE_DIRS})
add_definitions(${EIGEN_DEFINITIONS})

Any ideas?

as far as I see on groovy I had eigen in the find_package(catkin REQUIRED COMPONENTS ... eigen...) line in my CMakesLists.txt. If you get these massive amounts of compile errors, I'm almost certain somewhere eigen and bfl types collide. Maybe test in a separate small project how to integrate both.
