An empty output file when running Examples

Hi there,
I have installed Gulp recently, when I try to run any input example from examples folder, I get an empty output file without any error notification,
I used this syntax

gulp <example1. gin> file. got

hope I can find help
Thanks in advance

If you type exactly what you’ve put above then you’ll get an error message:

no such file or directory: example1.

as there are no spaces after the . in the file names. If the spaces are a typo in your message, then the problem is because you haven’t put the gulp executable in your path. See the run.sh (or even execute it) to see how things should work.
