autoconf/automake如何为configure脚本添加参数，比如--with-php=/path/to/phpsrc

[Hackerhell]

我在用autoconf/automake做一个工程的时候，该工程需要php源码目录。
如何为configure脚本添加参数，比如--with-php=/path/to/phpsrc，怎么才能使这个路径传递到最终的Makefile中去。
我看了半天，没看明白。谢谢。

AC_ARG_WITH([readline],
[AS_HELP_STRING([--without-readline],
[disable support for readline])],
[],
[with_readline=yes])

LIBREADLINE=
AS_IF([test "x$with_readline" != xno],
[AC_CHECK_LIB([readline], [main],
[AC_SUBST([LIBREADLINE], ["-lreadline -lncurses"])
AC_DEFINE([HAVE_LIBREADLINE], [1],
[Define if you have libreadline])
],
[AC_MSG_FAILURE(
[readline test failed (--without-readline to disable)])],
[-lncurses])])


你自己在google code中搜索 AC_ARG_WITH就可以找到好多了
