I wanted to build the arbusub firmware from scratch. I followed the steps shown in Build ArduSub · GitBook
I configured the board using the command,
./waf configure --board px4-v2
for which the output was the following:
ardusub$ ./waf configure --board px4-v2
Setting top to : /home/abel/px4_docs/Source_Code/ardusub

Then I build using the command,

to which I get an error message
