[Buildroot] AVR32 libiberty build failure

[Robin Gilks]

At least I think thats the problem...

gcc builds OK and at the next step on a default config build for a 
atngw100 it fails.

build output attached.

Does this work with the current stable, buildroot gcc, i.e. our 4.2.1 with
buildroot patches?
It seems that you are using something like:
toolchain_build_avr32/gcc-4.1.2-avr32-2.0

I think it is better to check against 4.1.2,
since there is no later port for AVR32.

The problem occurs in "gcc-*/libstdc++-v3/configure" if 
"gcc_no_link" is "yes".

This is set to "yes", if linking fails in "gcc-*/ltconfig".
For the AVR32 the linker fails because crt1.o is not found
(See log below)

I checked the staging dir, and there is no crt1.o there
when gcc-*-final is built

I searched for crt1.* in the gcc source tree,
only gcc/config/sh/crt1.asm exists.

IIRC, I have seen similar problems with ARM & C++

I build with c++,locale, gettext and libintl

I guess I was being a bit optimistic hoping that the default config for 
a target would actually work!

Has anyone tested the 
buildroot/target/device/Atmel/atngw100/atngw100_defconfig file or am I 
missing something in what is in svn at present... or am I perhaps going 
about it the wrong way - I assumed I should copy this to the top level 
.config and run 'make oldconfig' then 'make'

There has been some changes, which has killed the AVR32 toolchain
in the main trunk, and I am trying to find out why.
You can try the Buildroot at http://www.atmel.no/buildroot/

I'm getting much further now but I had to patch the Makefile in 
gcc-final/gcc to get the path correct for ORIGINAL_AS_FOR_TARGET as 
configure had made it an absolute path instead of relative to (or 
directly pointing to) the staging_dir directory (i.e. it had 
/usr/bin/.... instead of /home/...../staging_dir/usr/bin/...)

I think the derivation of this value is buried in the m4 scripting of 
configure.ac but I can't make head nor tail of that!!
