Installation Issues about mrs_uav_system HOT 13 CLOSED

Looks like there was some problem with the installation of the simulation. If you go to ~/mrs_workspace/src is there a symlink to the simulation? If not, you should add it (go to the ~/mrs_workspace/src and call ln -s ~/git/simulation), then install the simulation again (just to be sure) - run ~/git/simulation/installation/install.sh. Recompile the workspace (go to ~/mrs_workspace and call catkin clean and then catkin build).

After this, try to run one of the example tmux scripts.

Dan I decided befor reading your advices to reinstall all the package again, and then I got several compilation errors:
I will post some:

Hmmm, this looks like a lower level problem. What kind of computer do you use (CPU and how much RAM)? And what version of Ubuntu are you on?

I also checked if the simlink was there, and it was. Then run the run ~/git/simulation/installation/install.sh
After trying to catkin build it again it seams like the problem is at mrs_uav_odometry compilation. It takes much more time than the other, and them the system shutdown the process. Only guessing of course

this error - c++: internal compiler error: Morto (program cc1plus) often shows up when you run out of RAM. You can open htop during compilation to see if you are running out of RAM. You have only 6GB, which is not much, and your CPU has 8 threads, which is a lot, so it will compile 8 packages at once and might run out of RAM.

You can try to expand your swap file - https://bogdancornianu.com/change-swap-size-in-ubuntu/
Or run catkin build -j1 which will compile only with one thread, so you do not run out of RAM (it will also be much slower)

from mrs_uav_system.

Just to make sure I understood.
Do I have to re install all again or only do a catkin clean and after a catking build -j1 ?
I already have 4 GB of swaap, and you are right, the RAM memory is going out

from mrs_uav_system.

You probably do not need to reinstall, just try catkin clean; catkin build -j1

I compiled it all again, this time running one package per time. After I tried to only to open an empy world with roslaunch

lucas@lucas:~/mrs_workspace$ roslaunch mrs_simulation simulation.launch gui:=true
RLException: [simulation.launch] is neither a launch file in package [mrs_simulation] nor is [mrs_simulation] a launch file name
The traceback for the exception was written to the log file

After that I tried to run the tmux_exemple

lucas@lucas:~/mrs_workspace/src/simulation/example_tmux_scripts/one_drone_gps_baro$ ./start.sh

export UAV_NAME=uav1; export RUN_TYPE=simulation; export UAV_TYPE=t650; export WORLD_NAME=simulation; export SENSORS=""
waitForSimulation; roslaunch mrs_uav_status status.launch
lucas@lucas:/git/simulation/example_tmux_scripts/one_drone_gps_baro$ export UAV_NAME=uav1; export RUN_TYPE=simulation; export UAV_TYPE=t650; export WORLD_NAME=simulation; export SENSORS=""
lucas@lucas:/git/simulation/example_tmux_scripts/one_drone_gps_baro$ waitForSimulation; roslaunch mrs_uav_status status.launch

Now I think I am getting closer. I forgot to bash the /devel/setup.bash. Now the empty world is doing ok
But when I try to spawn UAV it says:
lucas@lucas:~$ spawn_uav
[rospack] Error: package 'mrs_simulation' not found

from mrs_uav_system.

Looks like the simulation is not installed properlly. Go to ~/git/simulation and call git pull. Then run the simulation install script again, and recompile the mrs_workspace (catkin build -j1, or maybe -j2 to make it a bit faster).

from mrs_uav_system.

Just small advices: Error: package 'mrs_simulation' not found is a standard ROS error. It says, that it cannot find the package from which we are launching a launch file. There may be various reasons for that.

1. You did not source the workspace which contains the package. In our case, this should be done automatically, check if you have the following line in the .bashrc file: source ~/mrs_workspace/devel/setup.bash
2. The package is not compiled. Then, find the package and try to compile it. The package is in the ~/mrs_workspace/src/simulation/ros_packages/mrs_simulation

Please, post your logs as formatted text, it is much easier to read then.

Guys
Now I think it is working. I don´t know how to thank you for the pacience. I will now begin studing the topics, and when I have more doubts I will post it in another topic
Best Regards
