Description:
------------
We're installing PHP on our Server.
The OS is CentOS 6.5 x86_64.
We've settled all the problems and errors occurred during configuring and make it successful.
It seemed good when we entered 'make' until it was stuck on 'Generating phar.php'.
We waited and waited, but it seemed no more information updated.
It was halted on.
We had nothing to do but change the version of PHP, almost all PHP-5.3, 5.4, 5.5, and 5.6, but it was no use.
We've also searched on Search engine for a long time, but got no solution.
We hope somebody here could offer some help.
Thanks.

---------------
