??? - I thought -n was the same as --dry-run.

[nix-shell:~/cmdstan]$ make -n 4 examples/bernoulli/bernoulli
make: *** No rule to make target '4'.  Stop.

I think you might mean “-j4”

yes -n is the same as --dry-run.

perhaps make is not finding the right makefile?
try this:

make --debug=a | head -20

output on my machine:

Thanks for the quick responses :) - I don't know why but it is now working. It might have been that I was trying to use a different C++ compiler or that the submodules hadn't populated when I thought they had - this seemed to do the trick

bash-3.2$ git submodule update --init --recursive
