Assembler messages:
Fatal error: unknown MCU: avrtiny
I used this command to configure:
../gcc-5.3.0/configure \
--prefix=/usr/local/gcc-4.6.2-avr-unknown-elf \
--target=avr-unknown-elf --build=i686-pc-mingw32 \
--enable-languages=c,c++ --with-newlib \
--disable-__cxa_atexit --disable-nls \
--disable-threads --disable-shared --enable-static \
--disable-win32-registry --disable-sjlj-exceptions \
--with-dwarf2 --with-gmp=/usr/local \
--with-mpfr=/usr/local
The corresponding prerequisites were installed in the /usr/local directory and
newlib was added to the source tree of gcc-5.3.0
