I am running ROS kinetic on ubuntu mate 16.04 lts on Raspberry pi 3. I have 3 packages in my src file at the moment, beginner_tutorials, rplidar, hector_slam. The problem appears to be with hector_slam, but I have experienced it with rplidar as well. Whenever I do catkin_make, after a certain percentage(not fixed!) of make process the system (Raspberry Pi 3) gets hanged and there is no way to get around it except restarting. Need help asap please. Thanks

Hi - first comment suggest you make your titles a little more meaningful. Secondly the issue you describe is very vague. Can you at least provide the the output from catkin_make.

I expect you need to increase your shared memory size. Also try running catkin_make -j1 (i.e. just use one core)

Sorry for that. I'll be careful next time. As I said before, the system is hanged! I cannot do anything and its just stuck. I am attaching an image here http://imgur.com/a/IM9ey .

@MarkyMark2012 I think I found the problem . I watched the memory using "watch -n 0.5 free -m" as the build process went on. Turns out that the memory is running out.here is the picture when memory almost runs out and rapsberry pi freezes. Any solution?

@MarkyMark2012 I have resolved the issue by adding a swap partition following steps given in this link .

Cool - pleased to hear it. Thought swap size might have been the issue. M

I can't see the images - However I expect the solution was to increase the swap space
