Error about linking `avr-gcc`

[gregorni]

I have set up an environment and cloned the template, but when I do cargo run in the project directory, I get an error about cargo not being able to link avr-gcc.

Full error message

I'm wondering if it may have to do with the fact that I installed avrdude with Homebrew, and avr-gcc with dnf.

I'm running Universal Blue (which is based on Linux Fedora Silverblue) version 39, but I'm building the project in a toolbx container for normal Fedora. I'm trying to build for an Arduino UNO.

Maybe you are missing the avr-libc? I am seeing

-lc: No such file or directory

in your error log. This indicated that the attempt to link libc failed.

Indeed, I was missing that. Installed it, and everything works now. Thanks! :heart:
