Using Phoronix Test Suite version 4.8.5 and Ubuntu 12.04 LTS 64-bit with all updates and latest stable kernel (currently 3.12.1).
Unfortunately after installing PHP-GTK 64-bit version and changing the file /etc/php5/cli/php.ini and adding:
... to Dynamic Extensions section
... I get the message:
... and it is true - such library does not exist regardless I installed it from Phoronix website as mentioned previously.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/php_gtk2.so' - /usr/lib/php5/20090626/php_gtk2.so: cannot open shared object file: No such file or directory in Unknown on line 0
Why does not Phoronix itself give such instructions? Why not create such version of PTS, which will work out of the box after installing - also GUI!!!
So - such articles like PTS gets GUI just are worthless - GUI does not work at all - even after hacking based on information found from internet. I would expect such information from Phoronix itself and would expect working solution.
