I am going to convert laser data to cloud point by follow the sample, but there is an error, "fatal error: Eigen/Core: No such file or directory on ". Is there someone know why it cannot found Eigen/Core when I try to build the example as bellow. http://wiki.ros.org/laser_pipeline/Tu...

Environments: ubuntu 14.04, gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2, ROS-indigo

There is no use when I add the bellows to CMakeLists.txt.

find_package(catkin REQUIRED COMPONENTS nav_msgs roscpp sensor_msgs tf laser_geometry ) find_package(catkin REQUIRED COMPONENTS cmake_modules ) find_package(Eigen REQUIRED)

Thank you very much!

In your CMakeLists.txt file, find the include_directories macro. Make sure it has ${Eigen_INCLUDE_DIRS} in it, e.g.,

include_directories(include ${catkin_INCLUDE_DIRS} ${Eigen_INCLUDE_DIRS})

find_package(Eigen3 REQUIRED) include_directories(${EIGEN3_INCLUDE_DIR})

following above stated commands doesn't help me. In addition to, 1) include_directories(include ${catkin_INCLUDE_DIRS} ${Eigen_INCLUDE_DIRS}) 2) find_package(Eigen3 REQUIRED)

adding following line helped me to compile with out any issues

target_link_libraries( your_executable ${catkin_LIBRARIES} Eigen3::Eigen )
