Ubuntu
gcc-avr package

The avr-gcc version (5.4.0) is a bit aged compared to a possible 8.3.0.

Asked by Stefan Rueger

The gcc-avr package provides a relatively old avr-gcc version of 5.4.0. Arch Linux, in comparison, provides the relatively recent version of 8.3.0-1. This newer compiler version creates markedly different, and apparently more efficient code - savings in terms of code size and in terms of execution time.

To wit, when calling avr-gcc --version, the output is "avr-gcc (GCC) 5.4.0
Copyright © 2015 Free Software Foundation, Inc...". What it should be is "avr-gcc (GCC) 8.3.0 ... 2019..."

Arch is a rolling release distribution so will have bang up to date packages. Ubuntu is not so...it doesn't

Can you help with this problem?
