Could not find a package configuration file provided by "RTABMap" (requested version 0.11.10)

[78226415]

Hi everyone, I have a building problem when build the last one step for the source, in the Install RTAB-Map ros-pkg in your src folder of your Catkin workspace. The command lines are: $ cd ~/catkin_ws $ git clone https://github.com/introlab/rtabmap_ros.git src/rtabmap_ros $ catkin_make

then an error is happen, the message is : `-- Using these message generators: gencpp;genlisp;genpy CMake Error at rtabmap_ros/CMakeLists.txt:21 (find_package): By not providing "FindRTABMap.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "RTABMap", but CMake did not find one.

Could not find a package configuration file provided by "RTABMap" (requested version 0.11.10) with any of the following names:

RTABMapConfig.cmake
rtabmap-config.cmake

Add the installation prefix of "RTABMap" to CMAKE_PREFIX_PATH or set "RTABMap_DIR" to a directory containing one of the above files. If "RTABMap" provides a separate development package or SDK, be sure it has been installed.

See also "/home/liguangxi/catkin_ws/build/CMakeFiles/CMakeError.log". make: *\ [cmake_check_build_system] Error 1 ` it seems can not find the RTABMap package, but i have made it installed at last two or three steps in the whole installation. Would some one help me? thanks

Hi,

Where rtabmap libraries are installed (step 2 from build-from-source)? It should be installed in your catkin workspace (~/catkin_ws/devel) or in /usr/local. CMake should be able to find the installed RTABMapConfig.cmake file in one of those paths (note that if installed in ~/catkin_ws/devel, make sure you did after $ source ~/catkin_ws/devel/setup.bash to update the ROS search path).

cheers

I used this command line instand of it : $ sudo apt-get install ros-indigo-rtabmap-ros

thanks all the same!

But step 2 tells to install it to the ~/rtabmap directory. I faced the same error as @78226415 when tried to follow the instruction of building from source. I fixed the problem by the command: export RTABMap_DIR=~/rtabmap/build/. But maybe the cmake option -DCMAKE_INSTALL_PREFIX=~/catkin_ws/devel could help either.

@matlabbe it would be cool if you could revise this step in the instruction.

Thanks!

Hi,

With:

$ cd ~
$ git clone https://github.com/introlab/rtabmap.git rtabmap
$ cd rtabmap/build
$ cmake .. 
$ make
$ sudo make install

the last line "sudo make install" will install rtabmap in /usr/local directory. If your PATH has /usr/local/bin in it, CMake should be able to find RTABMapConfig.cmake installed in /usr/local/lib/rtabmap-0.XX without the need to export RTABMap_DIR. Same thing if rtabmap is installed in your catkin devel space (e.g., ~/catkin_ws/devel), cmake should be able to find it if you did source ~/catkin_ws/devel/setup.bash (which puts ~/catkin_ws/devel in the PATH).

If you don't install rtabmap (not doing the last line above), RTABMap_DIR should be indeed set to rtabmap/build directory so that CMake can find it.

cheers, Mathieu

Ooops, sorry, I really missed sudo make install command 🙃 I appreciate your help!
