17.1 Obsolete config.status Invocation
config.status now supports arguments to specify the files to
instantiate; see config.status Invocation, for more details.
Before, environment variables had to be used.
— Variable: CONFIG_COMMANDS
The tags of the commands to execute. The default is the arguments given
to AC_OUTPUT and AC_CONFIG_COMMANDS in
configure.ac.
— Variable: CONFIG_FILES
The files in which to perform ‘@variable@’ substitutions.
The default is the arguments given to AC_OUTPUT and
AC_CONFIG_FILES in configure.ac.
— Variable: CONFIG_HEADERS
The files in which to substitute C #define statements. The
default is the arguments given to AC_CONFIG_HEADERS; if that
macro was not called, config.status ignores this variable.
— Variable: CONFIG_LINKS
The symbolic links to establish. The default is the arguments given to
AC_CONFIG_LINKS; if that macro was not called,
config.status ignores this variable.
In config.status Invocation, using this old interface, the example
would be:
config.h: stamp-h
stamp-h: config.h.in config.status
CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_FILES= \
CONFIG_HEADERS=config.h ./config.status
echo > stamp-h
Makefile: Makefile.in config.status
CONFIG_COMMANDS= CONFIG_LINKS= CONFIG_HEADERS= \
CONFIG_FILES=Makefile ./config.status
(If configure.ac does not call AC_CONFIG_HEADERS, there is
no need to set CONFIG_HEADERS in the make rules. Equally
for CONFIG_COMMANDS, etc.)
