when installing, catkin_make error

[DoranLyong]

Hi, when I followed section to install, I meet some problem in last .

I installed 'RTAB-Map standalone libraries' in ' catkin_ws/devel ' folder

problem

And, finally did git clone in catkin_ws . But, When I typed $ catkine_make ( I didn't check out from 'catkin_ws') I got this error beta@alpa:~$ cd catkin_ws/ beta@alpa:~/catkin_ws$ git clone https://github.com/introlab/rtabmap_ros.git src/rtabmap_ros Cloning into 'src/rtabmap_ros'... remote: Counting objects: 3329, done. remote: Compressing objects: 100% (45/45), done. remote: Total 3329 (delta 18), reused 0 (delta 0), pack-reused 3284 Receiving objects: 100% (3329/3329), 2.24 MiB | 566.00 KiB/s, done.

what is this error??? I looked for this issue: https://github.com/introlab/rtabmap_ros/issues/11 because I thought It is similar . but , I think it isn't

Please, give me a answer

rtabmap libraries should not be extracted in catkin/devel space. By "install in catkin/devel" I mean the CMAKE_INSTALL_PREFIX below. From the step one of rtabmap_ros installation instructions:

$ cd ~
$ git clone https://github.com/introlab/rtabmap.git rtabmap
$ cd rtabmap/build
$ cmake -DCMAKE_INSTALL_PREFIX=~/catkin_ws/devel ..  [<---double dots included]
$ make -j4
$ make install

rtabmap is extracted in Home folder, then on "make install", it is installed in catkin_ws/devel.

Ah, Thanks. I didn't understand what you mean well.

I do $ sudo apt-get remove ros-indigo-rtabmap ros-indigo-rtabmap

and than reinstall . the install is successful
