Every Autoconf-generated configure
script must finish by calling
AC_OUTPUT
. It is the macro that creates the `Makefile's and
optional other files resulting from configuration. The only other
required macro is AC_INIT
(see section Finding configure
Input).
If AC_CONFIG_HEADER
, AC_LINK_FILES
, or
AC_CONFIG_SUBDIRS
has been called, this macro also creates the
files named as their arguments.
A typical call to AC_OUTPUT
looks like this:
AC_OUTPUT(Makefile src/Makefile man/Makefile X/Imakefile)
You can override an input file name by appending it to file, separated by a colon. For example,
AC_OUTPUT(Makefile:templates/top.mk lib/Makefile:templates/lib.mk)
If you pass extra-cmds, those commands will be inserted into
`config.status' to be run after all its other processing. If
init-cmds are given, they are inserted just before
extra-cmds, with shell variable, command, and backslash
substitutions performed on them in configure
. You can use
init-cmds to pass variables from configure
to the
extra-cmds.
If you run make
on subdirectories, you should run it using the
make
variable MAKE
. Most versions of make
set
MAKE
to the name of the make
program plus any options it
was given. (But many do not include in it the values of any variables
set on the command line, so those are not passed on automatically.)
Some old versions of make
do not set this variable. The
following macro allows you to use it even with those versions.
make
predefines the variable MAKE
, define output
variable SET_MAKE
to be empty. Otherwise, define SET_MAKE
to contain `MAKE=make'. Calls AC_SUBST
for SET_MAKE
.
To use this macro, place a line like this in each `Makefile.in'
that runs MAKE
on other directories:
@SET_MAKE@
