Hi Krishnan, I remember that I also failed to build m5threads on a particular system, but I managed to build it on another system with a relatively old config (I have attached the output m5threads object files for x86 and ARM v7 to this email). If I remember correctly, that system had the Linux kernel 3.19 and gcc 4.8. You should be able to link the attached object file to your multi-threaded program compiled on a system with a newer kernel/compiler. Hope this helps.
