rtabmap would not compile

[Y.C]

Hi,

I need to reinstall rtabmap on my laptop.

I am following the installation guide on this page:https://github.com/introlab/rtabmap_ros

using sudo apt-get install ros-indigo-rtabmap-ros  didn't get me anywhere, so I have decided to build it from source.

I have followed the instruction until I use catkin_make to build the package in ROS when the following errors appeared:

-- rtabmap_ros: 9 messages, 6 services
-- WITH costmap_2d
CMake Error at rtabmap_ros/CMakeLists.txt:180 (target_link_libraries):
  Target "voxel_grid" of type EXECUTABLE may not be linked into another
  target.  One may link only to STATIC or SHARED libraries, or to executables
  with the ENABLE_EXPORTS property set.


-- WITH octomap
CMake Error at rtabmap_ros/CMakeLists.txt:201 (target_link_libraries):
  Target "voxel_grid" of type EXECUTABLE may not be linked into another
  target.  One may link only to STATIC or SHARED libraries, or to executables
  with the ENABLE_EXPORTS property set.

.......


There are other error messages like this. It all has to do with "voxel_grid". But I don't know what when wrong.'

Not sure what I can do with it.

Can someone please help me?

It is strange, "voxel_grid" is from PCL. I've built again on my Virtual Machine (Indigo) and no problems.

What do you mean by "didn't get me anywhere"? The binaries should be installed like any other ROS binaries.

cheers

Honestly, I am not sure what is happening here.

When I use "apt-get", I can install the program, but I cannot run it. I input 'rtabmap' in the terminal, the rtabmap logo shows up quickly before it was forced to quit, and says segmentation fault.

This problem also occured the last time when I tried to install it. I fiddled with it and eventually was able build it from source, but this time I guess I am just not that lucky.
