PHP编译安装报错：configure: error: mcrypt.h not found. Please reinstall libmcrypt

我是在CentOS6.5安装php5.5.28这个版本，PHP编译代码如下：

./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-mysql=/usr/local/mysql --with-mysqli=/usr/local/mysql/bin/mysql_config --with-mysql-sock=/tmp/mysql.sock --with-gd --with-iconv --with-zlib --with-fpm-user=php --with-fpm-group=php --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-pear --with-gettext --enable-session  --with-curl --enable-exif

安装过程不再赘述。因为在编译安装时没有把mcrypt这个扩展编译进去，所以在phpmyadmin里有这样一句提示：

缺少 mcrypt 扩展。请检查 PHP 配置。

另外在独立安装mycrypt扩展时，报错：

configure: error: mcrypt.h not found. Please reinstall libmcrypt.

现在把mcrypt扩展安装过程贴出来，希望对遇到此类问题的朋友有帮助：

1.首先编译安装  libmcrypt,  mhash,  mcrypt  二进制源码包。

========================================

下载libmcrypt-2.5.8.tar.gz

tar zxvf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8

./configure --prefix=/usr/local/libmcrypt

make

make install

=========================================

下载mhash-0.9.9.9.tar.gz

tar zxvf mhash-0.9.9.9

cd mhash-0.9.9.9

./configrue --prefix=/usr/local/mhash

make

make install

=========================================

tar zxvf mcrypt-2.6.8.tar.gz

cd mcrypt-2.6.8

export LD_LIBRARY_PATH=/usr/local/libmcrypt/lib:/usr/local/mhash/lib

export LDFLAGS="-L/usr/local/mhash/lib -I/usr/local/mhash/include/"

export CFLAGS="-I/usr/local/mhash/include/"

./configure --prefix=/usr/local/mcrypt --with-libmcrypt-prefix=/usr/local/libmcrypt

make

make install

=========================================

cd /usr/local/src/develop/php-5.5.28/ext/mcrypt

/usr/local/php/bin/phpize

./configure --with-php-config=/usr/local/php/bin/php-config  --with-mcrypt=/usr/local/libmcrypt

make

make install

生成的mcrypt.so文件已经被发送到 /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so

因为我在php.ini设置extension_dir = /usr/local/php/extensions,

所以需要执行：

cp /usr/local/php/lib/php/extensions/no-debug-non-zts-20121212/mcrypt.so  /usr/local/php/extensions

然后在php.ini里面添加：

extension=mcrypt.so

重启php，执行： service php-fpm restart

运行phpinfo(),发现新增了mcrypt扩展项，而且phpmyadmin里面关于mcrypt的提示也不见了。

 

 

在安装过程中走了弯路，一度鄙视这种编译安装方式，多亏了这位大神发的帖子帮忙。

64位Centos报错：

configure: error: Cannot find ldap libraries in /usr/lib.

解决方法是执行命令： cp -frp /usr/lib64/libldap* /usr/lib/
