Error Building Linux Kernel Project

It looks like the cygwin extensions didn't install properly on your system... I say this because it can't find gcc, and it thinks you're trying to build an i386 architecture.

Can you send me the following info?

(1) the contents of: c:\Program Files\Microtronix Nios II Linux Distribution\install_settings.cache

(2) The value of the following SYSTEM environment variable: $QUARTUS_ROOTDIR

(3) Where your altera nios2 kit was installed (typically c:\altera\kits\nios2)

(4) Where you installed Quartus II v5.0

For point (2), start up a Nios II SDK shell and type:

echo $QUARTUS_ROOTDIR

to retrieve the value I'm looking for.

I should be able to get you up and running with the above info...
