I am working on a cmake project and I would like to set a directory variable containing the correct compile command. I added this to the root directory of the project in a .dir-locals.el file:

;;; Directory Local Variables
;;; For more information see (info "(emacs) Directory Variables")

((nil .
      ((indent-tabs-mode . t)
       (fill-column . 80)
       (compile-command . "cd build && make"))))

If I enter describe-variable for the variable fill-column, I get the message that This variable's value is directory-local, set by the file .... The variable is set from its default of 70 to 80 instead. However, the compile-command variable is unchanged. Is there a bug in the file?

The variable compile-command is not buffer local by default, thus you can not set it per buffer. To change this add the following to your init file:

(make-variable-buffer-local 'compile-command)
