编译 PHP时提示mysql 错误

编译PHP: ./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --enable-fpm --with-fpm-user=php-fpm --with-fpm-group=php-fpm --with-mysql-dir=/usr/local/mysql --with-mysql-sock=/tmp/mysql.sock --with-libxml-dir --with-gd --with-jpeg-dir --with-png-dir --with-freetype-dir --with-iconv-dir --with-zlib-dir --with-mcrypt --enable-soap --enable-gd-native-ttf --enable-ftp --enable-mbstring --enable-exif --enable-zend-multibyte --disable-ipv6 --with-pear --with-curl=/usr/bin/ --with-openssl

提示错误信息：

configure: error: mysql configure failed. Please check config.log for more information

1.将--with-mysql=/usr/local/mysql  修改为--with-mysql-dir=/usr/local/mysql 解决。

原因不明,可能是版本的问题。因为教程里是正常的。

2.libmcrypt 和libmcrypt-devel包未安装 。
