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-libcBut the status quo is, that the process fails because of an unresolved circular dependency:- avr-libc needs avr-gcc - avr-gcc needs avr-libc headersI'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 installBut 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?

I've built the AVR toolchain from scratch a number of times and also have a set of ports files for MacPorts that successfully builds. I've never encountered a situation where avr-gcc needed the headers from avr-libc. What languages are you asking avr-gcc to build? I only build c and c++. It may require the headers if you try to build java, fortran, etc. The gcc configure command for my ports looks like:
configure --prefix=/opt/local --infodir=/opt/local/share/info -- mandir=/opt/local/share/man --target=avr --program-prefix=avr --with- included-gettext --enable-obsolete --with-gxx-include-dir=/opt/local/ avr/include/c++/4.3.2 --enable-languages="c,c++"
