Peeter,
As you know, I am climbing the learning curve w/ avr-gcc.
Will you detail how I can duplicate your results? This weekend I was
unable to get simulavr installed on Debian - even after setting the
compiler to locate the bfd and libiberty.a files. I thought about simply
installing the current stable version of the avr toolchain under /usr so
as to then obtain a successful install of simulavr. Debian has aptitude
to install simulavr automatically, and this installation expects the bfd
library under /usr But this is not my first choice and have yet to do
it.
My toolchain is under /home/patrick/linuxtooling/ to allow tooling up
for multiple targets and development tools (and easier debugging) rather
than settling for the most common method under /usr.
So, any suggestions on how I might work with you?
