Troubleshooting

Question:

When I run make in the RIOT repository, I get something like:

mkdir -p 
mkdir: missing operand
Try 'mkdir --help' for more information.
Makefile:6: recipe for target 'all' failed
make: *** [all] Error 1

What am I missing?

You have to run `make` from within your application directory, not directly from the RIOT repository.
