I think I have found one problem
"toolchain_build_avr32/gcc-4.1.2-initial/gcc/as" is a script file
which should call the assembler.

It contains

#!/bin/sh
exec "$@"

and should contain:
#!/bin/sh
exec <buildroot>/build_avr32/staging_dir/bin/avr32-linux-uclibc-ld "$@"

I modified this by hand, and now it seems to continue further.
Off to bed...

This should really not mather, because the PATH variable should be set
before starting to compile the cross-compiler.

Perhaps this is as easy as a missing TARGET_CONFIGURE_OPTS?

I have added ORIGINAL_*_FOR_TARGET /DEFAULT_*/*_FOR_TARGET to
HOST_CONFIGURE_OPTS 
(it fails during gcc-4.1.2-final) 
And now use HOST_CONFIGURE_OPTS for configure and make.

As a result, it seems that ld/nm/objcopy now has the right path,
but the assembler doesn't.

	     echo '#!$(SHELL)' > as; \
	     echo 'exec $(ORIGINAL_AS_FOR_TARGET) "$$@"' >> as ; \

results in as containing
+++++++++++++++
#!/bin/bash
exec "$@"
---------------

I suspect, I have to configure with "-with-gnu-as" or with 
"-with-as=$(STAGING_DIR)/../*-as"as well,
(It is already configured with "-with-gnu-ld")
and the machine is working overtime, testing that at the moment.

Best Regards

Passing CONFIGURE_OPTS to make after an autoconf'igured package was
configured is not needed.

We don't need to pass --with-gnu-ld nor --with-gnu-as. If sombody finds
a different assembler or linker, then this is a consequence of something
going wrong previously. The target is linux and not irix or something
like that.

Assuming that the package is well behaved.

Packages which contains subdirectories which are 
configured separately typically fail miserably if you do not 
make $(TARGET_CONFIGURE_OPTS) -C $(DIR)
Haven't you noticed that?

I dread packages which contains configuration down a third level...

Well gcc-4.1.2 doesn't find anything apparently 
unless you bombard it with information during configure.
-with-as=$(CROSS_COMPILE)as seems absolutely neccessary.
or ORIGINAL_AS_FOR_TARGET will be empty.

Empty ORIGINAL_AS_FOR_TARGET is why sysroot fails.
Still gcc-4.1.2 has problems with libtool.

Yea, I know. This and the fact that gcc-4.1.x is not the current release
series, so i decided to leave it alone.

>Still gcc-4.1.2 has problems with libtool.

4.1 has lots of problems, and lots of problems were thusly fixed in the
current (and upcoming) release(s). Trying to fix 4.1 it doesn't make
sense to me, there's enough to do in current stuff that is way more
interresting, at least IMO.

But i'm digressing..

Maybe, but I do not have time to port AVR32 to gcc.
Someone else will do that in due time.
I think I should be able to get the current release to build though...

At the moment, the current release *is* 4.2.1 ;)

When gcc-4.1.2 is build
"toolchain_build_avr32/gcc-4.1.2-initial/gcc/<app>" contains

app=as
#!/bin/sh
exec  "$@"

app=collect-ld
#!/bin/sh
exec <buildroot>/build_avr32/staging_dir/avr32-linux-uclibc/bin/ld "$@"

app=nm
#!/bin/sh
exec /usr/bin/nm "$@"

------
I am changing all to:

#!/bin/sh
exec <buildroot>/build_avr32/staging_dir/avr32-linux-uclibc/bin/<app>
"$@"
