Errors Installing mrs_uav_system about mrs_uav_system HOT 8 CLOSED

Hi, it seems that dependencies for the simulation were not properly installed. If you followed the instruction for mrs_uav_system, you should have the script for installing the dependencies in ~/git/simulation/installation/install.sh. Try to run the script manually to see if it is without error.

source ~/git/simulation/installation/install.sh

Note: Be sure that you have up-to-date version of the simulation repository. Call

cd ~/git/simulation
git pull

Thank you for the reply. I will try it

I have a strong suspecion it might be related to a lack of memory. When I installed the system my installation failed due to a lack of memory when building the mrs_gazebo folder. The error you're experiencing seems to be an error caused from that.

The solution would be to go into the install files and comment out the preset catkin configuration and then build it again using your own catkin settings with fewer amounts of packages / jobs

I think i might be facing a similar issue and it still doesn't work on my end too. Tried partition the storage space for more ram but to no avail.

Hi, please update mrs_uav_system repository and try to call install again. If it still crashes, modified these lines https://github.com/ctu-mrs/mrs_uav_system/blob/master/scripts/set_mrs_workspace.sh#L45-L52 by adding parameter -j $number_of_cores_for_build. For example for the first line building using only 4 cores:

catkin build mavros -c --mem-limit 75% -j 4

from mrs_uav_system.

My solution was to build it first with standard settings.
Then removing the catkin configuration and running it again with -j1 -p1

Hello, yesterday I figured out the problem. My logfile past the almost 2gb because of that, it had been giving the error. I deleted the logfile then installed again. Then it works now.

An additional option that I would recommend is to set up a swap of an appropriate size, such that your total RAM+SWAP is roughly 2.5 times [GB] the number of your CPU virtual threads. Then, you won't have to be careful about that anymore and the compilation will be way faster with all cores. Example for 16GB SWAP:

sudo swapoff -a
sudo dd if=/dev/zero of=/swapfile bs=1G count=16
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
grep SwapTotal /proc/meminfo
