Composer Install report libmysqlclient_18 error

System Environment: Ubuntu 14.04 64-bit
PHP Version: 7.0.0
MySQL version: 5.7.10
Composer Version: 1.2.1

PHP is the source package installed, MySQL is the binary package after decompression installed

Require file contents are as follows

{        "require" : {                "swiftmailer/swiftmailer": "5.3.*@dev",                "phpoffice/phpexcel": "dev-master"        }}

The following error is reported after execution, no matter what the above require write

$ composer installLoading composer repositories with package informationphp: relocation error: php: symbol inflateInit2_, version libmysqlclient_18 not defined in file libmysqlclient.so.18 with link time reference

There's a libmysqlclient.so.18 under the/usr/lib/.
Also try the installation to do the following:

$ sudo apt-get install libmysqlclient-dev

Ask the great God, is I php what things do not add the compile option or how to drop ... I really don't understand.
