Installing TinyECC using Tossim

I first install Ubuntu 10.04 using VMWARE on Windows7. I installed TinyOS 2.1.2 and everything is going well. Flashing and other examples are working correctly. Tossim works for these examples as well. make micaz sim command builds successfully. I need to simulate the signtaure algorithm, so I want to install TinyECC-2.0, but getting the following error:

Is there anyone working on this?

According to the docs ( http://discovery.csc.ncsu.edu/software/TinyECC/README.txt ):

NNM.nc has built-in assembly code to speed up the natural number of operations. Inline assembly code is written for Atmega128l (MICAz), MSP430 (TelosB / Tmote Sky) and XScale (Imote2). If you want to use TinyECC for other platforms, you must comment out "#define INLINE_ASM" in NN.h, or implement your own inline assembly code.



If you're not ready to write your own inline asm, I would look at changing the definition for INLINE_ASM.
