It seems avr-libc 1.8.1 will not build with gcc 4.8.1, but vanilla gcc 4.9.1 works fine. I rolled my own .debs from the regular Debian gcc-4.9.1 sources and vanilla 1.8.1 from the project website.
As I understand, the AVR toolchain on Debian is built from Atmel sources, but these are currently out of date. It seems Atmel toolchain developers are now actively submitting patches to the gcc project, before making a new version of their own toolchain available. This begs the question, wouldn't it be better if Debian avr- packages started using vanilla sources instead? It would help developers stay more up to date, and avoid relying on patched third party sources. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
