• obsoleted Use AC_DEFINE_DIR instead.

This macro _AC_DEFINEs VARNAME to the expansion of the DIR variable, taking care of fixing up ${prefix} and such.

Note that the 3 argument form is only supported with autoconf 2.13 and later (i.e. only where _AC_DEFINE supports 3 arguments).

Examples:

  AC_DEFINE_DIR_(DATADIR, datadir)
  AC_DEFINE_DIR_(PROG_PATH, bindir, [Location of installed binaries])

This macro is based on Alexandre Oliva's AC_DEFINE_DIR.

AC_DEFUN([AC_DEFINE_DIR_], [
  test "x$prefix" = xNONE && prefix="$ac_default_prefix"
  test "x$exec_prefix" = xNONE && exec_prefix='${prefix}'

  ac_define_dir=`eval "echo [$]ac_define_dir"`
