I am running a Fedora linux system (currently Fedora 30). The first thing to do is install the compiler:
dnf install avr-gcc dnf install avr-libcThis pulls in binutils as a dependency (as it should):
(1/2): avr-binutils-2.32-1.fc30.x86_64.rpm (2/2): avr-gcc-9.2.0-1.fc30.x86_64.rpm avr-libc-2.0.0-7.fc30.noarch.rpm
