Problem with OJS install

Hello everybody:
I have a problem with OJS install. I have Xampp program and I did every step of the tutorial but it doesn’t work. I don’t why but this is the data:

Deprecated : Non-static method PKPApplication::defineExposedConstant() should not be called statically in /opt/lampp/htdocs/rodrigocabrera.com/lib/pkp/classes/core/PKPApplication.inc.php on line 545

Deprecated : Non-static method PKPApplication::getExposedConstants() should not be called statically in /opt/lampp/htdocs/rodrigocabrera.com/lib/pkp/classes/core/PKPApplication.inc.php on line 513

Many thanks in advance!
