dnl Obviously there is duplication here wrt $SUBDIR_MAKEFILES.
|
|
dnl You _can_ use that variable in AC_CONFIG_FILES, so long as any directory
|
|
dnl using automake (ie lib/) is explicitly listed and not "hidden" in a variable
|
|
dnl (else you get "no `Makefile.am' found for any configure output").
|
|
dnl This will work, but you get a config.status that is not quite right
|
|
dnl (see http://lists.gnu.org/archive/html/bug-autoconf/2008-08/msg00028.html).
|
|
dnl That doesn't have any obvious consequences for Emacs, but on the whole
|
|
dnl it seems better to just live with the duplication.

dnl You might wonder (I did) why epaths.h is generated by running make,

dnl rather than just letting configure generate it from epaths.in.
|
|
dnl One reason is that the various paths are not fully expanded (see above);
|
|
dnl eg gamedir=${prefix}/var/games/emacs.
|
|
dnl Secondly, the GNU Coding standards require that one should be able
|
|
dnl to run `make prefix=/some/where/else' and override the values set
|
|
dnl by configure. This also explains the `move-if-change' test and
|
|
dnl the use of force in the `epaths-force' rule in Makefile.in.
