[En-Nut-Discussion] Nut/OS ARM eCross-EABI toolchain

[diek]

Hallo all,

I'm trying to develop a remote control with eNetsam7X and NUT-OS for 
amateur radio.
My operating system was Ubuntu 11.10, it ran just fine with NUTOS 5.02 
and the compiled binary toolchain ARM eCross-Eabi from 
http://www.embedded-it.de

Now I have installed the new Kubuntu 12-04 LTS, and have big problems,
and I need some help.

I've done:
I downloaded latest version from trunk
and compiled with:  . /autogen.sh --disable-nutconf
make.
It works well.

But toolchain does not build, because arm-eCross-eabi-gcc is not recognized.

The path in .bashrc is set for gcc:
export PATH=$PATH:~/arm-eCross-eabi/bin

I think the binaries will not be accepted.

I have downloaded the Sourcen ARM eCross EABI Toolchain-Builder inkl. 
Patches 
<http://www.embedded-it.de/bsp-download/arm-eCross-eabi-source-2011-02-02.tar.gz>
and try to compile.
Unfortunately, there is an error message.

I can not understand this message. The working compiler gcc version 
4.6.3 is available (Ubuntu / Linaro 4.6.3-1ubuntu5).
I do not know what to do here.

Is there someone who could help me a little bit to solve the problem.

Any answer would help.
Thank you very much.
