configure script must call
AC_INIT before doing
anything else. The only other required macro is
(see section Creating Output Files).
configurechecks for this file's existence to make sure that the directory that it is told contains the source code in fact does. Occasionally people accidentally specify the wrong directory with `--srcdir'; this is a safety check. See section Running
configureScripts, for more information.
Packages that do manual configuration or use the
might need to tell
configure where to find some other shell
scripts by calling
AC_CONFIG_AUX_DIR, though the default places
it looks are correct for most cases.
configurescripts that are in directory dir. These are auxiliary files used in configuration. dir can be either absolute or relative to `srcdir'. The default is `srcdir' or `srcdir/..' or `srcdir/../..', whichever is the first that contains `install-sh'. The other files are not checked for, so that using
AC_PROG_INSTALLdoes not automatically require distributing the other auxiliary files. It checks for `install.sh' also, but that name is obsolete because some
makeprograms have a rule that creates `install' from it if there is no `Makefile'.
