If I try to verify (compile) the example sketch blink, arduino says: Error compiling unknown MCU 'atmega328p' specified ... attiny28 /usr/share/arduino-0017/hardware/cores/arduino/wiring_shift.c:1: Fehler: MCU »atmega328p« nur für Assemblierung unterstützt. Do I need dev-embedded/arduino-0018? Reproducible: Always
Still some information abuot the toolchain: root@thinkpad:/usr/local/portage/dev-embedded/arduino(115)# qlist -Iv avr cross-avr/avr-libc-1.6.2 cross-avr/binutils-2.20.1-r1 cross-avr/gcc-4.2.4-r1 dev-embedded/avrdude-5.8
After installing the toolchain with: USE="-openmp" crossdev -t avr -s4 -S --g 4.3.3 --without-headers the issue disappeared. (I forget the --g 4.3.3 option during my last install).
