compile and the current directory

compile and the current directory

[Kai Grossjohann]

I have a project which contains a Makefile at its root directory.
Running make for me means to change to that directory before running
make.

(Actually, I'm running another command, not make.)

The problem with "just" running make from the current directory is
that it is a different directory depending on the file I'm editing.

Has somebody made something that would allow me to just invoke M-x
compile RET from any directory and that makes sure that the command is
invoked from the right directory, and that Emacs knows about it?

(I could specify "make -C $HOME/work/foo" as the command if I was
using make.)

   I have a project which contains a Makefile at its root directory.
   Running make for me means to change to that directory before
   running make.

I have been meaning to implement something like that, but for
`recompile' instead.  Make more sense to have `compile' record the
directory one compiles in, and then have `recompile' restore it.
Anyway, I whiped up the following patch, it seems to work.

This is a little bit cleaner:

(let ((default-directory (or compilation-directory default-directory)))
   (apply 'compile-internal ...))

Interesting approach.  This reminds me that it is probably possible to
go to the *compilation* buffer and do `g' or `M-x revert-buffer RET'.
That might be rather convenient.  Hm.  Yeah, why not make a private
keybinding that pops me into the *compilation*  buffer.  Then I could
do C-c c g or somesuch.  (C-c c goes to the *compilation* buffer,
say.)
