Again Linker errors

General JUCE discussion
#1

Hi, just updated to latest juce version and had to change my l&F class to inherit from LookAndFeel_V2.

But now I am struggeling with the below linker errors. I have rebuilt the project with Introjucer after updating

and slightly get wondering whether it is my stupidity to fail to get it to work...

My L&F class is a Singleton.

Any hint is much appreciated!

#2

It looks like you may have some code that's trying to invoke parent class methods by saying e.g. "LookAndFeel::drawButtonText". Since these are now pure-virtual methods, you'd need to change it to LookAndFeel_V2::drawButtonText or whatever. Strange that it'd let you get as far as the link stage though.

Oh yeah, my bad.

Thanks Jules!
