Re: [avr-libc-dev] Are there any autoconf/automake experts around?

Not an expert my any means but I've messaed around with things a bit.

Even without the run-time library, you should still be able to produce
an "executable" (using the -nostdlib options et al).

Building a normal gcc compiler (I haven't played withy 4.x yet) goes
through a multi-stage process of building a gcc with no runtime,
followed by building the runtime. followed by building the final gcc
with runtime. I've been using the uClibc build scripts to do this for
linux based systems. So, something similar should be possible for
avr-gcc as well.

Can you send the configure script being used? (perhaps off-list since
it will be quite large).

Which version of automake/autoconf are you using?

What would I need to do to reproduce your environment? I haven't yet
tried building any version of avr-gcc but have built numerous arm
compilers. Are you running under linux or cygwin?
