The atngw100small also fails with the following error:
configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[2]: *** [configure-target-libiberty] Fel 1
make[2]: *** Inv?ntar oavslutade jobb...
make[1]: *** [all] Fel 2
This is the same error you get when you try to build the ARM with
softfloat.
Since the AVR32 does not have an FPU, this is always softfloat.
There is something screwed up with the linking process
when using the current trunk.
Not all libraries are found, so gcc configure
cannot link and this sets some flags resulting in the error above.
The ARM softfloat patch was trying to overcome the fact
that libgcc.a is not used/found by the uClibc build.
It allows uClibc build to complete, but gcc-final
still bombs out on the linking process
because crt1.o is not found.
Then the GCC_NO_EXECUTABLES is set, and
when tested for this later, the build is terminated.
crt1.o is an x86 thing and should not affect arm or avr32
but it certainly does.
Have tried to find a workaround, but failed so far.
Until a solution is found, the www.ateml.no/buildroot
seems the way to go.
Once a solution is found, then ARM softfloat will probably
work as well.
Using the external toolchain option would be one alternative.

Hi:
I am compiling buildroot for generic arm on i386 PC (see .config file
attached). uClibc compilation fails:

I cannot reproduce this. I've double-checked that the sample arm926t
(integrator CP, IIRC) builds and works fine with and without softfloat
(after deleting that wrong uClibc-0.9.29-soft-fp.patch, of course).
Can you reproduce this error with the provided defconfig in
target/device/ARM/integrator_whatever ?

This is not really an accurate approach i'd say (but i didn't look
closely), but i take it that you're aware of this.

uCLibc compiles with this, but not without this.
The compile does not complete so it does not make
any sense to keep it.
I will try the integrator and see what is the difference.
Maybe it is related to the host?

OK, Now I have built the integrator stuff as well,
and it builds well with soft-float!
Thanks for the tip.
The immediate difference I could see was
that the integrator is built using "arm926ejs"
instead of using "generic-arm" which I have used so far.
I will try to rebuild the integrator modified for "generic-arm"
and see how it goes.

Integrator still works with "generic-arm" instead of "arm926ejs"
Next thing to try is EABI instead of OABI.
