So... it can't find memcpy for some reason?
I'm about to try with llvm-3.2 to see if that's different.
I don't think different llvm will help here. This is purely linker issue. Somehow you link with different set of libraries probably. Anyway it looks like: http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka3934.html -- this function is part of common ARM EABI so it should be implemented by your C compiler tool-chain. You just need to find out where it is and how you may use it. Karel
