mapOptmization process has died #198

Closed MaxandreOgeret closed 3 years ago

MaxandreOgeret commented 4 years ago

Hello, I get this error when I start the launchfile :

[mapOptmization-7] process has died [pid 6638, exit code 127, cmd /home/xxxxxx/catkin_pkg/devel/lib/lego_loam/mapOptmization __name:=mapOptmization ].

gtsam is at the right version : 4.0.0-alpha2. How to solve this ? thanks

Solved when adding /usr/local/lib to ld libraries : 

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Hi,I have the same problem with you, Can you explain the solution in more detail？ thank you .

MaxandreOgeret commented 4 years ago

No problem, the problem was that some libraries were missing. They were installed but not available because not in the LD_LIBRARY_PATH environment variable. So adding /usr/local/lib directory to the variable solved my problem.

You just have to run this command before running the launch file : export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

Make sure gtsam is at the right version also. If it doesnt work, open the launchfile et use rosrun to run each node one by one and see if you get a better error message there

Hope it helps !
