Sorry, it doesn't build. -->
The first steps (until the last one) are working as expected.

  $ make L4ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi- menuconfig

Through this step I set the L4 build directory with
"/home/abc/Work-Repositories/sepia/tudos_Vnew/l4/build".
Then I tried to build it with the default settings:
-------------------------------------------------------------
 make L4ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-
make -C /home/beresford/Work-Repositories/sepia/l4linux
O=/home/beresford/Work-Repositories/sepia/l4linux/build/.
L4 source directory: /home/beresford/Work-Repositories/sepia/l4linux
PWD=/home/beresford/Work-Repositories/sepia/l4linux make -C
/home/beresford/Work-Repositories/sepia/l4linux -f
/home/beresford/Work-Repositories/sepia/l4linux/arch/l4/Makefile.l4conf
O=/home/beresford/Work-Repositories/sepia/tudos_Vnew/l4/build/
L4X_LOOP_CHECK=1
OUTPUT=/home/beresford/Work-Repositories/sepia/l4linux/build/Makeconf.l4conf

---------------------------------------------------------
 
and then I changed the architecture from x86 to arm (within the L4Linux
menuconfig entry).
In that case I get the following error:
---------------------------------------------------------
make L4ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabi-

The first make setup and the make after, works. But then I have to
change into the obj/l4linux/arm-up directory, if I understand it right.

this call ends up with the following error: menuconfig ->l4linux -> arch x86

Thank you for your help! I would be really glad if you could provide me
maybe some more ideas to solve it.

Kind regards,
