having issues building nard

[Ronny Nilsson]

Hi timball
It seems you have somehow mixed you PC native compiler and the ARM cross 
compiler. The x86_64 compiler of your PC most likely can't build for ARM, but 
it has tried before giving up. Later on, when you use nard-cc it too gets 
confused. Am I right guessing you have tried modifying the kernel 
configuration? Things like this might happen then. There is a guide for that 
in the documentation:
http://www.arbetsmyra.dyndns.org/nard/advance.html#kernelconf

You need to clean the tree and start over:
	cd nard/apps/linux-kernel/
	make clean
	make

If that doesn't work your kernelconf might be invalid. 
Delete "platform/skeleton/linux-rpi-3.10.y.config" and make distclean instead 
of clean above. It will however delete the tree so backup any changes you 
would like to keep first.

Hope it helps!
