dnl Comments in this file start with the string 'dnl'.
dnl Remove where necessary. This file will not work
dnl without editing.

dnl Check PHP version:

AC_MSG_CHECKING(PHP version)
AC_TRY_COMPILE([#include "php/main/php_version.h"], [
#if PHP_MAJOR_VERSION < 5 || (PHP_MAJOR_VERSION == 5 && PHP_MINOR_VERSION < 2)
#error  this extension requires at least PHP version 5.2.0
#endif

[AC_MSG_ERROR([need at least PHP 5.2.0])])

dnl If your extension references something external, use with:

PHP_ARG_WITH(msgpack, for msgpack support,
Make sure that the comment is aligned:
[  --with-msgpack             Include msgpack support])

dnl PHP_ARG_ENABLE(msgpack, whether to enable msgpack support,
dnl Make sure that the comment is aligned:
dnl [  --enable-msgpack           Enable msgpack support])
