I installed php 5.5.1 on centos 5.8 with the following setting

'./configure'' - prefix = / usr / local / php'' - with-libdir = lib64'' - with-config-file-path = / etc / php / php.d'' - disable-debug'' - with-pic'' - disable-rpath'' - without-pear'' - with-bz2'' - with-curl'' - enable-gd-native-ttf' '--with-gdbm'' - with-gettext'' - with-gmp'' - with-iconv'' - with-openssl'' - with-pspell'' - with-zlib'' --with-layout = GNU'' - enable-exif'' - enable-ftp'' - enable-sockets'' - enable-sysvsem'' - enable-sysvshm'' - enable-sysvmsg' '--enable-wddx'' - with-kerberos'' - enable-shmop'' - enable-calendar'' - with-mysqli'' - with-apxs2'' - with-mysql'' --with-gd'' - with-jpeg-dir = / usr'' - disable-dba'' - without-unixODBC'' - enable-mbstring'' - with-pdo-mysql'' - -enable-zip'' - with-mcrypt'' - enable-soap'' - enable-opcache'

php.ini

zend_extension=opcache.so   
opcache.memory_consumption=256    
opcache.interned_strings_buffer=8    
opcache.max_accelerated_files=4000    
opcache.revalidate_freq=60   
opcache.fast_shutdown=1   
opcache.enable_cli=1   
opcache.enable=On   
extension=/usr/local/lib/php/extensions/no-debug-non-zts-20121212/intl.so

php在安装过程中没有显示任何错误,但 opcacheintl 未出现在phpinfo()的输出中(httpd重启)

这里有什么问题?请帮我修理一下 .
