linux gmp phpize 报错

"

先说下我的安装步骤

1.cd ext/gmp

2.phpize

3. ./configure --with-gmp

4.make && make install(完成无错，有提示：Installing shared extensions:     /alidata/server/php/lib/php/extensions/no-debug-non-zts-20090626/)

5.更改php.ini

extension = "/alidata/server/php/lib/php/extensions/no-debug-non-zts-20090626/gmp.so"

6.重启php-fpm

7.报错：PHP Warning:  PHP Startup: Invalid library (maybe not a PHP library) '/alidata/server/php/lib/php/extensions/no-debug-non-zts-20090626/gmp.so' in Unknown on line 0

ps:文件目录地址正确

整个安装过程都没有错，是什么地方出了问题求指导
