# SYNOPSIS
|
|
#
|
|
# AX_CONFIGURE_ARGS
|
|
#
|
|
# DESCRIPTION
|
|
#
|
|
# Helper macro for AX_ENABLE_BUILDDIR.
|
|
#
|
|
# The traditional way of starting a subdir-configure is running the script
|
|
# with ${1+"$@"} but since autoconf 2.60 this is broken. Instead we have
|
|
# to rely on eval'ing $ac_configure_args however some old autoconf
|
|
# versions do not provide that. To ensure maximum portability of autoconf
|
|
# extension macros this helper can be AC_REQUIRE'd so that
|
|
# $ac_configure_args will always be present.
|
|
#
|
|
# Sadly, the traditional "exec $SHELL" of the enable_builddir macros is
|
|
# spoiled now and must be replaced by "eval + exit $?".
|
|
#
|
|
# Example:
|
|
#
|
|
# AC_DEFUN([AX_ENABLE_SUBDIR],[dnl
|
|
# AC_REQUIRE([AX_CONFIGURE_ARGS])dnl
|
|
# eval $SHELL $ac_configure_args || exit $?
|
|
# ...])
