Cannot build utilities

[Fezikk]

I finished building and flashing the firmware onto my Nexus 6p, and am now trying to build & install the utilities. However, when I run make in nexmon/utilities I get the following error:

make -C nexutil/.
make[1]: Entering directory '/home/oliver/nexmon/utilities/nexutil'

My NDK version is 11c & I am using Ubuntu 18.04.

Any help or suggestions are greatly appreciated. Thank you
