Fixed! And thanks for pointing it out.

Thank you 130s for your answer. I found my mistake. I tried to install two distros of ROS to access older packages but did not readjust my sources.list and keys. After setting these for kinetic, I was able to access the package without problem.

2016-06-09 12:24:40 -0500 asked a question mavros missing on kinetic?

Hello,

I was using mavros on Indigo and cannot manage to install again on kinetic. The package does not show up in the list of ros-kinetic-* packages.

I additionally tried to install it manually, following the instructions on this page: https://github.com/mavlink/mavros/blo...

However, when replacing my distro from jade to kinetic in the following command line:

rosdep install --from-paths src --ignore-src --rosdistro jade -y

I get the following error: E: Unable to locate package ros-kinetic-control-toolbox

I could not find the package in the list of ros-kinetic-* packages and I made sure to update my system and upgrade it. Has anyone managed to install mavros on kinetic?

Hello Meng, I did not do anything more than what I described above. After updating my kernel to a new distribution, the problem went away. Such an upgrade is not a trivial thing to do as it might break other packages. Do it carefully, and only if nothing else works.

2016-02-22 16:53:07 -0500 answered a question symbol lookup error / undefined symbol

I fixed my issue by completely reinstalling Ubuntu. The new 14.04.4 LTS version was available and after installing it, upgrading the kernel to 4.2 and reinstalling ROS, there was no more problem. Maybe the problem could have been fixed by simply running sudo apt-get dist-upgrade. If someone encounters the same problem and fixes it that way, please edit the answer or leave a comment.

I tried again to uninstall and reinstall ROS and all my pcl libraries; the problem remains. Does anybody else encounter this issue?

Hello,

I am trying to run some pcl filters using their ROS nodelet wrappers in a launch file but I always get the same error:

/opt/ros/indigo/lib/nodelet/nodelet: symbol lookup error: /opt/ros/indigo/lib//libpcl_ros_features.so: undefined symbol: _ZN3pcl6search6KdTreeINS_8PointXYZEEC1Eb

Running: c++filt _ZN3pcl6search6KdTreeINS_8PointXYZEEC1Eb

Returns: pcl::search::KdTree<pcl::PointXYZ>::KdTree(bool)

It appears that the library implementing KdTree for pcl is missing. I however have the following libraries installed on my machine (via apt-get): libpcl-kdtree-1.7 libpcl-kdtree-1.7-dev libpcl-kdtree-dev

I followed the advice listed here: http://answers.ros.org/question/12126...

I updated my system (Ubuntu 14.04 64 bits, ROS indigo, kernel 3.19). I removed all ROS packages and their dependencies, then reinstalled them with sudo apt-get install ros-indigo-desktop-full. Yet, the problem is still here.

I also looked at this post: http://answers.ros.org/question/22063... . However, I am using core packages from ROS, available via apt-get, and therefore I do not have access to the CMakeLists.txt file to add the missing library.

Has anyone met the same issue?

Thanks a lot! You confirmed the problem was not related to my installation. I found a work-around and posted it in the answer section. I will also report the issue so that the wiki page can be updated.

2016-01-23 07:46:22 -0500 answered a question data_recorder node missing from rtabmap_ros package

As gvdhoorn pointed out, the executable data_recorder is not listed in the CMakeLists file and therefore, is not built into the package.

A way around is to adapt the sample launch file data_recorder.launch to your needs. I tested it on my system and it works perfectly.

2016-01-23 04:51:25 -0500 asked a question data_recorder node missing from rtabmap_ros package

Hello,

I recently installed rtabmap_ros and rtabmap on Ubuntu 14.04, using apt-get:

sudo apt-get install ros-indigo-rtabmap-ros
sudo apt-get install ros-indigo-rtabmap

I would like to record stereo images to a database, as is done in this sample launch file. However, I noticed that the node "data_recorder" is missing.

rosrun rtabmap_ros data_recorder
[rosrun] Couldn't find executable named data_recorder below /opt/ros/indigo/share/rtabmap_ros

The only nodes available from rtabmap_ros are the following:

rosrun rtabmap_ros 
camera              grid_map_assembler  map_optimizer       rtabmap             stereo_odometry     
data_player         map_assembler       rgbd_odometry       rtabmapviz

Am I missing a library to build this node? I did not receive any error or warning when downloading the packages from apt-get and my system is up-to-date.

Alternatively, is there another package that can build a database of stereo images to use with rtabmap odometry viewer tool?

Best Regards,

Audren

Thank you so much gvdhoorn! It worked and ROS can now retrieve the packages installed. All good.

2015-01-29 11:06:46 -0500 asked a question ROS does not detect packages installed with apt-get

Hello,

I tried to install packages to ROS indigo by running the command: sudo apt-get install ros-indigo-package name

The packages are downloaded and installed but neither roscd nor rosrun can find them, despite sourcing the file setup.bash after the download.

Am I missing a step?

Best Regards

2015-01-29 11:06:46 -0500 asked a question ROS Indigo does not recognise a package installed with apt-get install ros-indigo-*

Hi,

I installed ros indigo and wanted to add some packages like ardrone_autonomy and freenect_stack. I used the command: sudo apt-get install ros-indigo-package name

The packages are downloaded and installed without any errors but neither rosrun nor roscd finds them. I sourced the setup.bash file after the installation.

Am I missing a step?

Best Regards
