If `compilation-read-command' is non-nil (the default value is t) then "make -k" is always the default value for the compile command. To have the default value for the compile command be the last compile command you entered, set `compilation-read-command' to nil. Check the value of variable `compile-history' after step 2, using `C-h v'. If it includes the last compile command you entered, then the problem is not with savehist. In that case, you might want to report an Emacs bug for command `compile'. > > After step 2, visit `savehist-file'. What do you see recorded for > > `compile-history'? You should see something like (setq compile-history > > '("foobar")). > > What is 'savehist-file'? It's the variable that tells savehist where you want to save the histories. By default, its value is "~/.emacs-history". You can customize this variable. In sum, check the saved value of `compile-history'. If it looks good, then the problem is not with savehist.
