Cannot build code: make: *** [px4_fmu-v3_default] Error 1

[guroz]

Good morning,

I am entirely new to PX4 and I am probably missing something but I have been trying for 2 days and still cannot find out how to address my problem. I have followed the developer guidelines to install everything and I am following the Getting Started tutorial. When I try to build the code with :

make px4_fmu-v2_default

The code builds and everything is fine. However, I am using a Pixhawk 2.1 and therefore cannot upload this version to my board. When I try to build using

make px4_fmu-v3_default

it returns this error :

I am using macOS mojave 10.14.2 and just installed every toolchains, so they all are up to date.
Thank you in advance
