Hi guys,
i am trying to build the firmware on my Arch Linux computer. I use this guide for it: Building the Code · PX4 Developer Guide.
The simulated drone works but the next step (make px4fmu-v2_default) fails. It produces the following error:

I guess the problem is that it somehow doesn’t find the math library or something like that ? I am not the best in c programming tbh. Can someone help me with that ?
Thanks a lot
