Hi,
I am trying to annotate my benchmark with m5ops and use KVM to expedite the
simulation.
However, when I am trying to use the address-based APIs such
as m5_switch_cpu_addr, I am getting the following link error:
/usr/bin/ld: ../../util/m5/build/x86/out/libm5.a(m5op_addr.o): relocation
R_X86_64_32S against symbol `m5_mem' can not be used when making a PIE
object; recompile with -fPIE
If I use the nm tool to look into the lib file (libm5.a), I see the symbol
m5_mem is dangling.
The -fPIE is enabled, but the problem persists.
Thanks,
Majid
