编译 PHP make 的问题：*** [sapi/cli/php] 错误 1

这是我收到的消息：

在使用 Make 进行编译时，我也收到了很多警告。

例如：

zend_operators.c:2171:34: warning: 
  'finite' is deprecated: first deprecated in OS X 10.9
  [-Wdeprecated-declarations]
                    } else if (dval1 == dval2 && !zend_finite(dval1)) {

zend_compile.c:4010:9: warning: assigning
  to 'char *' from 'const char *' discards qualifiers
  [-Wincompatible-pointer-types-discards-qualifiers]
    lcname = hash_key->arKey;
           ^ ~~~~~~~~~~~~~~~

 'unsigned char *' converts between pointers to integer types with
  different sign [-Wpointer-sign]
                                    sc = YYCURSOR;
                                       ^
Zend/zend_ini_scanner.l:479:12: warning: assigning to 'unsigned char *' from
  'char *' converts between pointers to integer types with different sign
  [-Wpointer-sign]
            YYCURSOR = sc;

他们还有很多。

这是我的命令：

./configure --enable-fpm --with-pdo-mysql --with-mcrypt --with-zlib --with-openssl --with-curl

make

我以root身份登录。
