am following your guide from:

http://eleccelerator.com/wiki/index.p...

and I am now installing rtabmap_ros but I am getting these error,

when I run the command

catkin_make -j1 I get this error

CMake Error at /opt/ros/kinetic/share/catkin/cmake/catkin_workspace.cmake:100 (message): This workspace contains non-catkin packages in it, and catkin cannot build a non-homogeneous workspace without isolation. Try the 'catkin_make_isolated' command instead. Call Stack (most recent call first): CMakeLists.txt:69 (catkin_workspace) -- Configuring incomplete, errors occurred! See also "/home/pi/catkin_ws/build/CMakeFiles/CMakeOutput.log". See also "/home/pi/catkin_ws/build/CMakeFiles/CMakeError.log". make: [Makefile:1526: cmake_check_build_system] Error 1 Invoking "make cmake_check_build_system" failed*

after getting this error I run the command

catkin_make_isolated

as mentioned in the error

but this leads to this error

anyway to solve this problem ??
