[TYPO3-english] tt_news updater script broken

[joydeep at infoservices.in]

Hello,

I am trying to upgrade tt_news to 3.4.0 under typo3 4.5.22.
When ever I try the updater script, I get error as

Fatal error: Call to undefined method tx_ttnews_compatibility::testInt() in /var/www/project/typo3conf/ext/tt_news/class.ext_update.php on line 379
Call Stack

At line 379 I get 

if ($this->compatibility()-> testInt($v)) { 

According to  http://forge.typo3.org/issues/44091  I have changed it to

if ($this->compatibility()-> t3lib_div::testInt($v)) {

and then I get

unexpected T_PAAMAYIM_NEKUDOTAYIM

Could anyone suggest a fix please ?

Thanks
