If you’re running it in the source directory, where you just built it, you need to run it in the terminal using a relative path, like this:
Assuming that the built binary is in the directory you’re currently in.
Otherwise, if you’re not in the directory, you could run it using an absolute path.
E.g.
But as KGIII said, if you run the
make install
command (you may need to be root, so use sudo, or su to root before running the command, if required.)
Then it will be installed somewhere in $PATH, most likely /usr/local/bin. And you will be able to run it directly as
