Having decided to build a simulation environment using DronecodeSDK on ubunto 16.04.5, I used the process described on [Building SDK from source](https://sdk.dronecode.org/en/contributing/build.html). Then I built the [PX4 software](https://dev.px4.io/en/setup/building_px4.html) and also installed the[jMAVSim toolchain](https://dev.px4.io/en/setup/dev_env_linux.html) and [jMAVSim with SITL](https://dev.px4.cc/en/simulation/jmavsim.html) With all these dependencies installed I can load PX4 using make posix\_sitl\_default jmavsim but when it tries to install the GUI it crashes. I’ve seen other threads discussing this issue, but have not been able to resolve it using these approaches. There are several references to graphics issues, but the crashing is troublesome. Any help will be appreciated. This is what I get: joe@joe-VirtualBox:~/src/Firmware$ make posix\_sitl\_default jmavsim ninja: Entering directory `/home/joe/src/Firmware/build/posix\_sitl\_default’ [1/1] cd /home/joe/src/Firmware/build/…/src/Firmware/build/posix\_sitl\_default SITL ARGS sitl\_bin: /home/joe/src/Firmware/build/posix\_sitl\_default/bin/px4 debugger: none program: jmavsim model: none src\_path: /home/joe/src/Firmware build\_path: /home/joe/src/Firmware/build/posix\_sitl\_default empty model, setting iris as default SITL COMMAND: /home/joe/src/Firmware/build/posix\_sitl\_default/bin/px4 /home/joe/src/Firmware/ROMFS/px4fmu\_common -s etc/init.d-posix/rcS -t /home/joe/src/Firmware/test\_data INFO [Unknown] Creating symlink /home/joe/src/Firmware/ROMFS/px4fmu\_common -\> /home/joe/src/Firmware/build/posix\_sitl\_default/tmp/rootfs/etc * * * | \_\_\_ \ \ \ / / / | | |_/ / \ V / / /| | | \_\_/ / \ / /_| | | | / /^\ \ \_\_\_ | \_| / / |\_/ px4 starting.

> [@Joseph\_Marrone](#): > > joe@joe-VirtualBox:~/src/Firmware$ Looks like you’re running this in a virtual machine. Have you checked if 3D support is working correctly? Please check the virtual box settings, and make sure the guest extensions are installed correctly. ---

Once I went from a virtual machine to a direct install as host, the graphics problems went away. Evidently SITL needs a lot of horsepower that just isn’t there on a virtual machine. Now I will make ubuntu my host and Windows the guest. -Joe
