Missing avr-gcc; you need to crossdev -s4 avr ?

cwc

I'm not sure how to resolve this notification:

Messages for package dev-embedded/arduino-builder-1.5.4-r1:

Well, technically that's what you want to do.

hmm. behavior of this changed, it used to auto create the repo, mine got dumped in /usr/local/portage/cross-avr ...

Do you have a preferred location for overlay trees? just specify an empty directory beside the other overlays you might have.

This overlay is mostly empty, it's used to keep track of updates for the toolchain when you emerge @world (like cross-avr/gcc-13.1, etc.; they're usually just symlinks to the main repo) Just makes tracking a bit easier, plus you can put software you want to build for these alternate cross compile architectures that should not be built for the native architecture.

I don't use any IDEs but use make and avr-gcc to build binaries for old microcontrollers, and other than some bloat (and needing to use -Os), gcc works fairly well.

Thank you eccerr0r.

I'm going to work on this. I just need a little free time. Duty calls.

If I took the time and followed the docs I would have understood.
https://wiki.gentoo.org/wiki/Arduino

I did the following:
# mkdir -p /var/db/repos/portage-crossdev/{profiles,metadata}
# echo 'crossdev' > /var/db/repos/portage-crossdev/profiles/repo_name
# echo 'masters = gentoo' > /var/db/repos/portage-crossdev/metadata/layout.conf
# chown -R portage:portage /var/db/repos/portage-crossdev
# echo 'thin-manifests = true' >> /var/db/repos/portage-crossdev/metadata/layout.conf

#nano -lmc /etc/portage/repos.conf/crossdev.conf

[crossdev]
location = /var/db/repos/portage-crossdev
priority = 10
masters = gentoo
auto-sync = no

The following failed:
#crossdev -s4 --stable --portage --verbose --target avr

This line of code fixed the problem:
USE="-openmp -hardened -sanitize -vtv" crossdev -s4 --stable --portage --verbose --target avr

Error:

WARNING - Cannot auto-configure CHOST avr;
!!! You should edit /usr/avr/etc/portage/make.conf /usr/avr/etc/portage/profile/make.defaults /usr/avr/etc/portage/profile/use.force

This solved the above notification:
USE="-openmp -hardened -sanitize -vtv" crossdev -s4 --stable --portage --verbose --target avr
