Next: Private macros, Previous: Public macros, Up: Autoconf macros supplied with Automake [Contents][Index]
Although using some of the following macros was required in past
releases, you should not used any of them in new code. Running
autoupdate
should adjust your configure.ac
automatically (see Using
autoupdate
to Modernize configure.ac in The
Autoconf Manual).
AM_CONFIG_HEADER
¶Automake will generate rules to automatically regenerate the config
header. This obsolete macro is a synonym of AC_CONFIG_HEADERS
today (see Other things Automake recognizes).
AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL
¶If the use of TIOCGWINSZ
requires <sys/ioctl.h>, then
define GWINSZ_IN_SYS_IOCTL
. Otherwise TIOCGWINSZ
can be
found in <termios.h>. This macro is obsolete, you should
use Autoconf’s AC_HEADER_TIOCGWINSZ
instead.
AM_SYS_POSIX_TERMIOS
¶Check to see if POSIX termios headers and functions are available on the
system. If so, set the shell variable am_cv_sys_posix_termios
to
‘yes’. If not, set the variable to ‘no’. This macro is obsolete,
you should use Autoconf’s AC_SYS_POSIX_TERMIOS
instead.
