OK I give up.
I'm waiting for a working PHP 5.5 package since 2013 and it's not released yet.
I've been trying to compile my own PHP 5.5 and 5.6 for several days with no luck.
I'm tired. Every needed libraries are too old in the asustor toolchain.
We cannot do anything!
I tried Ubuntu PPAs but it's the same... Every needed libraries are too old!
PHP 5.3 is DEPRECATED now and php 5.6 is out for production since few weeks and we still are stuck with 5.3 on Asustor units.
I really don't understand why it is so long to upgrade.
C'mon Asustor guys it's time to upgrade to PHP 5.6 (native or apk I don't care plus 5.3 webapps work under 5.6)!!!
Synology have upgraded to 5.5 so...
