Define the variable with defvar before use. You use the variable only buffer-locally, so put a call to make-variable-buffer-local after the defvar form. Then you don't need to use make-local-variable. ^ permalink raw reply [flat|nested] 5+ messages in thread

This is not an error message but a warning. Best is to fix it to "silent" the byte compiler but anyway you can ignore it. Try to defvar your variable to nil and see what happens (it is often enough).
