I’ve found the issue, it was the
--disable-multiliboption. I’ll push a fix asap.This is fixed! 🎉 you can brew remove and brew install avr-gcc@8 again 😃
yes, sorry for that! while working on the new bottle system, I took the opportunity to update the formula and follow what brew/core does. That’s how I reintroduced the multilib thing…
it will soon be fixed.
Yes, you cannot have two different versions of gcc linked at the same time.
avr-gcc will by default me linked and available in path. If you want another version linked, you must unlink the main one and manually link a @x version.
Yes, I’ve got the same issue, I’m investigating.
