Attiny not compiling with Servo.h

I recently bought an attiny85 and I added an external clock to it because I thought by adding an external 16Mhz clock it would be able to work with the servo.h library . Was I completely wrong or there is hope that I am just doing something wrong with the connections or the coding . The crystal is connected on pin 2 and 3 of the attiny with two 22pf capacitors to ground and the code loaded is the knob example that comes with the arduino ide

I googled it and got some results about an Servo8bit.h library but it wasn’t working quite well so I thought that I should go for an upgrade .
Ps I will post the code later when I get access to my computer
