[avr-libc-dev] headers only / bootstrapping an avr toolchain

[Sven Köhler]

Hi,

at the moment, i'm trying to help the Gentoo developers to find a way of 
bootstrapping an avr toolchain.

Normally Gentoo's tool called "crossdev" would do the following:
- install binutils-avr
- install avr-libc-headers
- install avr-gcc
- install avr-libc

But the status quo is, that the process fails because of an unresolved 
circular dependency:

- avr-libc needs avr-gcc
- avr-gcc needs avr-libc headers

I'd need a way, to install avr-libc's headers only. I need to bypass all 
checks for avr-gcc. I dream of doing something like:

- ./configure --headers-only
- make all
- make install

But avr-libc's current configure doesn't allow that to happen. It always 
checks for avr-gcc, but of course it doesn't find it.


Can you think of a way to enhance avr-libc with a "install headers-only" 
mode?

If not, how is an avr toolchain supposed to be bootstrapped?
