I installed Geiser in Emacs. In a scheme buffer, if I run C-c C-s, I can choose Chicken as the implementation. If I run C-c C-z, it starts an REPL and switches to it. My buffer seems to be correctly linked to the REPL. However, if I hit C-c C-c on a function definition, nothing is happening. Going to the REPL and calling my function fails (unbound variable). C-c C-c is bound to geiser-eval-definition.
What am I missing in my setup?
