[image] kevindsp: cc1plus: out of memory allocating 1048576 bytes after a total of 8019968 bytes Looks like you ran out of memory. Is this in a virtual machine? And if so, could you raise the available RAM?

Hi,Julian! Thank you for your reply.But I don’t use virtual machine.I run it in ubuntu which is installed directly in my PC.So，how could I fix the problem? thank you!

Ok, in that case try building with less cores: make px4_sitl gazebo -j1

ı have problem like this: and also ı tried this make px4_sitl gazebo -j1but ı m taking: yusuf@yusuf-GE60-0NC-0ND:~/src/Firmware$ make px4_sitl gazebo_plane [2/5] Performing build step for ‘sitl_gazebo’ [22/28] Building CXX object CMakeFiles…r/src/gazebo_usv_dynamics_plugin.cpp.o FAILED: /usr/bin…

I have same wrong with you.Have you fixed it ?

Yes ,I did now ;solved.You go to home/username/src/Firmware/Tools/sitl_gazebo/src/gazebo_usv_dynamics_plugin.cpp and open gazebo_usv_dynamics_plugin.cpp.Then go to 251.line and change this line ,like 253.line: and save this substitution.And again write: ``` make px4_sitl gazebo or what do you want …

I got the same error, SOLVED. Thank you so much !!

@yalcinyusuf That is not the solution. The problem is that you are using a unsupported version of the ignition::math library. Your issue is unrelated to the initial issue posted in this thread
