The versions of avr-gcc in linux repositories mostly do not work.
I've been trying to build avr-gcc from sources,
using scripts provided by Bingo600.
So far the effort has not succeeeded.
See here
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=42631
and here
http://www.avrfreaks.net/index.php?name=PNphpBB2&file=viewtopic&t=124056
for some of what has gone before.
I ran ./buildavr-toolchain.sh 2>&1 | tee buildavr-toolchain.out
from
/home/hennebry/data/projects/avr/gcc/build-avr-gcc-4.5.1-binutils-2.20.1-libc-1.8.0-gdb-7.3.1-dude-5.11.1-avarice-2.12-aw/make-avr-gcc

gcc -static doesn't work?
libtool doesn't support shared libraries?
complex.h? Wow.
I did find this:
http://www.mail-archive.com/autoconf@xxxxxxx/msg09268.html ,
but I don't know what to do about it.
Eventually the script crashes,
complaining about the absence of build/genmodes .h .

The last line also contained control characters
that didn't cut and paste very well.
I'm told that this output is a symptom of running
the script from inside the build directory.
Since I didn't do that, there must be another explanation.
Any ideas?
