cannot compile multiple c files gcc [closed]

I have the following files in the same directory: main.c, game.c, player.c, queue.c I write gcc main.c game.c player.c queue.c -o server in terminal, it seams that it works ( I see all the warnings) and then I call ./server, but it shows an error : bash: ./server: No such file or directory Why does it happen?

I run the same project in CLion and it works.
