uclinux toolchain installation ( cross compiler setting error)

Hi,

I was working with trunk branch and the nios2install is for test-nios2 branch, so i have read something about git tool

0: internet connected

1: switch to nios2-test

at git repo ../uClinux-dist/

$git branch -l

test-nios2

* trunk

$git checkout test-nios2

$git branch -l

* test-nios2

trunk

2 : update

run ../nios2-linux/update

3: uClinux-dist/make menuconfig

ERROR: there is not any rule for target config.arch building

and i can see tha there is a link file named config.arch linked to vendors/Altera/nios2nommu/config.arch

¿?

THANKS IN ADVANCE
