I have compiled ruby for 32 bit architecture and my simics installation is also for 32-bit architecture.
I followed all steps mentioned in "First Steps Simics/GEMS on Ubuntu 7.10", author: Aleksandar Vitorovic, savitor@xxxxxxxxx


I have compiled ruby using following command

make PROTOCOL=MOSI_SMP_bcast DESTINATION=MOSI_SMP_bcast

here is the trace of compilation
