Library works on arduino Due but not on Zero (same sketch).

Hello, the title says it all. My code works fine when I upload it on the Due, but if I'll try to compile it for the Zero (SAMD21) I get these errors:

I can't tell for sure as you just dumping the error with no context, but you seem to be using a variable name that is already declared.

[EliasA97]

I don't think the the problem is naming. If so, then why it runs fine on the Due while giving problems on the Zero?

[thomasfredericks]

Again, you did not post your code or context hence one can only guess. But the compiler is complaining that select is being redefined. You also ALREADY SUBMITTED AN ISSUE WITH THIS AND I RESOLED IT : https://github.com/thomasfredericks/Bounce2/issues/72
