ROS Melodic is building from source , https://github.com/ros-perception/slam_gmapping, https://github.com/ros-perception/openslam_gmapping. I can run the launch successfully, but generate maps slowly or not updated, how can i do? Thanks!

which branch did you used for https://github.com/ros-perception/openslam_gmapping ? master or meldoic-devel?

3shao commented 5 years ago

Thank you for your reply. I use master, meldoic-devel didn't release. Now I use meldoic-devel , but when I run the launch, the error :

/opt/ros/melodic/lib/gmapping/slam_gmapping: symbol lookup error: /opt/ros/melodic/lib/gmapping/slam_gmapping: undefined symbol: _ZN8GMapping14sampleGaussianEdm

the 1.3.10 for https://github.com/ros-perception/slam_gmapping. How can I use the Correct version to compile?

I have the same problem with slow map generations on melodic-devel. Has anyone found a solution?

k-okada commented 4 years ago

can you provide how we can reproduce your problem? with simulation (http://wiki.ros.org/navigation_stage) or bug files?

@3shao, While doing catkin_make, have you used the argument -DCMAKE_BUILD_TYPE=Release? If not, then please try adding it, as I have observed significant performance improvements with 'Release' builds.
