Make sure you have cross-binutils selected and active. Simple test:

$ LANG=C avr-as --version
GNU assembler (Gentoo 2.32 p2) 2.32.0


$ binutils-config -l | fgrep avr
 [8] avr-2.32 *

[Comment 5 Nick Wallingford 2019-05-26 16:13:13 UTC]

`binutils-config avr-2.32` fixed that issue, and then avr-libc ran into a similar issue that was fixed with `gcc-config avr-9.1.0`, so immediate problem solved I guess. Should crossdev be running these commands automatically before it moves on to the next step? It seems odd that it isn't.

[Comment 6 Sergei Trofimovich (RETIRED) 2019-05-26 19:09:41 UTC]

Normally emerging new gcc target switches compiler on.

Probably we have some corner case like uninstall old version/install new version that leaves stale symlinks. Do you happen to remember what was the sequence if actions for you?

The following:
    $ qlop -lu | fgrep cross-avr
command might shed some light.

Let's close it as obsolete as there is no follow-up.
