| # 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 $? |
| # ...]) |
