15.1 Obsolete `config.status' Invocation

`config.status' now supports arguments to specify the files to instantiate, see 14. Recreating a Configuration, 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 14. Recreating a Configuration, 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.)
