cannot find libfovis when compiling

[alexr]

Hi,

I am doing a clean install for ROS kinetic and installing by source. I downloaded and compiled most of the external libraries before building rtabmap.
Here is how my

cmake

 looks like:

~/rtabmap/build$ cmake ..

   "/usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so"
but this file does not exist.  Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained

but not all the files it references.

-- The imported target "vtk" references the file

but not all the files it references.

Another thing, I have loam_velodyne in my catkin folder, however rtabmap is not able to find it. Can you suggest something.

Thanks

Hi Alex,

On my system I've built libfovis directly with catkin (in catkin workspace). For loam_velodyne, cmake should find it in your catkin_ws if you sourced ~/catkin_ws/devel/setup.bash:

$ cd rtabmap/build
$ cmake ..
...
-- Found libfovis: /home/mathieu/catkin_ws/src/libfovis/libfovis
-- Found loam_velodyne: /home/mathieu/catkin_ws/src/loam_velodyne/include;/usr/include/eigen3;/usr/local/include/pcl-1.8;/usr/include;/usr/include/ni;/usr/include/openni2;/usr/include/vtk-6.2;/usr/include/jsoncpp;/usr/include/freetype2;/usr/include/x86_64-linux-gnu/freetype2;/usr/lib/openmpi/include/openmpi/opal/mca/event/libevent2021/libevent;/usr/lib/openmpi/include/openmpi/opal/mca/event/libevent2021/libevent/include;/usr/lib/openmpi/include;/usr/lib/openmpi/include/openmpi;/usr/include/hdf5/openmpi;/usr/include/x86_64-linux-gnu;/usr/include/libxml2;/usr/include/python2.7;/usr/include/tcl;/opt/ros/kinetic/include;/opt/ros/kinetic/share/xmlrpcpp/cmake/../../../include/xmlrpcpp;/home/mathieu/catkin_ws/src/perception_pcl/pcl_conversions/include
...

$ ls ~/catkin_ws/src/libfovis/libfovis | grep fovis.hpp
fovis.hpp

 
With the PATH set like this (by ~/catkin_ws/devel/setup.bash):

$ env | grep PATH
PATH=/home/mathieu/catkin_ws/devel/bin:/opt/ros/kinetic/bin:...

cmake should be able to find those config files:

$ ls ~/catkin_ws/devel/share/libfovis/cmake
libfovisConfig.cmake  libfovisConfig-version.cmake

$ ls ~/catkin_ws/devel/share/loam_velodyne/cmake
loam_velodyneConfig.cmake  loam_velodyneConfig-version.cmake

cheers,

Hi,

This did not solved my problem. I tried to build it with catkin inside ~/catkin_ws/src as well.

cmake can find both the libraries (libfovus and loam_velodyne )inside the catkin_ws however, the error is still the same. cmake .. inside rtabmap cannot still find loam_velodyne.

Is it because I have also catkin_isolated packages inside my catkin_ws folder which is affecting rtabmap to find fovis.hpp?
I have to run ls ~/catkin_ws/src/libfovis/libfovis/libfovis | grep fovis.hpp   (Notice another libfovis folder at the end)
fovis.hpp

Thanks

[matlabbe]

Where are installed libfovisConfig.cmake and loam_velodyneConfig.cmake? Those are the files that cmake should find to say that the libraries are found.

What is the PATH?

$ env | grep PATH

[matlabbe]

Hi Alex,

The PATH seems wrong. After sourcing setup.bash in catkin_ws/devel (see ros instructions), the PATH should look more like this (on my system):

$ env | grep PATH
PATH=/home/mathieu/catkin_ws/devel/bin:/opt/ros/kinetic/bin...

The "catkin_ws/devel/bin" is before "/opt/ros/kinetic/bin", which is used by cmake to find the libraries built in your catkin workspace.

Maybe the isolated build doesn't create "catkin_ws/devel/bin". I don't use isolated builds so I am not sure how libraries can be linked from outside the workspace.

Another option is to set the path of libfovis and loam_velodyne config files:

$ cd rtabmap/build
$ cmake -Dloam_velodyne_DIR=~/catkin_ws/devel/share/loam_velodyne/cmake -Dlibfovis_DIR=~/catkin_ws/devel/share/libfovis/cmake

cheers,
Mathieu

[alexr]

Hi,

Still the same problem of not finding fovis.hpp.
I tried to uninstall everything and started from scratch and yet the same problem.
I am now thinking of installing the OS again and install everything fresh. Can you tell me whether the extra libraries
are actually helpful when building rtabmap (libfovis, viso2, etc).

Another thing, for opencv, do you recommend to install by source for ROS kinetic or the standalone opencv3 supplied by kinetic is enough to do good mapping. Same for g2o, should I go for the source install or libg2o is good enough.

Thanks

[matlabbe]

Hi Alex,

I took some time to try the installation from scratch too, using ros docker for convenience:

$ docker pull ros:kinetic-perception
$ docker run -it ros:kinetic-perception
# cd
# mkdir catkin_ws
# cd catkin_ws
# mkdir src
# cd src
# catkin_init_workspace
# git clone https://github.com/srv/libfovis.git
# git clone https://github.com/laboshinl/loam_velodyne.git
# cd loam_velodyne
// patching loam_velodyne (see below)
# git fetch origin pull/89/head:matlabbe
# git checkout matlabbe
# cd ../..
# catkin_make -DCMAKE_BUILD_TYPE=Release

// install all rtabmap default dependencies, for convenience, just install/remove the binary package from ros
# apt-get update
# apt-get install ros-kinetic-rtabmap-ros
# apt-get remove ros-kinetic-rtabmap

# cd
# source catkin_ws/devel/setup.bash
# git clone https://github.com/introlab/rtabmap.git
# cd rtabmap/build

From latest version of loam_velodyne, you need this patch to build it and to avoid linker errors with rtabmap.

For libfovis, I fixed the error of include not found in this commit. The error was that the kinetic branch on libfovis has been updated (putting all headers in a libfovis subdirectory) after I cloned the repository last year.


With OpenCV3 and g2o installed by ros kinetic, you should have the same performance. Libraries that are helpful for rtabmap is GTSAM (though g2o gives similar results for graph optimization) and libpointmatcher (useful if you are using laser scans).

cheers,
Mathieu

Hi Mathieu,

Thanks for checking that out. I will report back soon with my testss.

Thanks for your time.

[alexr]

Hi Mathieu

Just to report back, with the update libfovis could be found now. However, the loam_velodyne is still not found when invoking cmake ..

FYI, I patched it with your patch when install loam_velodyne in catkin_ws/src.

Thanks
