Hi Eberle, The Makefile builds TWO sets of binaries… one called test_XXX_p using the pthreads library, and one called test_XXX using the m5threads library (i.e. pthreads.o), so that seems to be ok… Was the same target name specified for both before?
Hmm, is the command I use to run the binary ok? ./build/X86_SE/m5.debug configs/example/se.py --cmd=m5threads/tests/test_pthreadsbasic Did you try X86 at all, or did you run the cross-compiled sparc binaries through M5? And using the same command as above (with SPARC instead of X86)?

Oh, right! You're using that makefile! I remembered that it had two problems! When it compiles, it executes the correct gcc command line and in the next line it executes a gcc line (if I remember correctly) using the system pthread library. Two make targets had this issue. Resulting in an incorrect binary. I presume that's what is happening. -- Eberle A. Rambo.

I did a make on the tests within m5threads using my system's regular gcc/g++ (for x86), and tried running one of the binaries through M5 in X86_SE mode like this: ./build/X86_SE/m5.debug configs/example/se.py --cmd=m5threads/tests/test_pthreadsbasic I get the following error: Global frequency set at 1000000000000 ticks per second 0: system.remote_gdb.listener: listening for remote gdb #0 on port 7000 **** REAL SIMULATION **** info: Entering event queue @ 0. Starting simulation... panic: Tried to write unmapped address 0. @ cycle 467000 [translate:/tmp/tukrishna/m5/build/X86_SE/arch/x86/tlb.cc, line 635] Memory Usage: 578888 KBytes For more information see: http://www.m5sim.org/panic/d71dd0bc Program aborted at cycle 467000 Firstly, I hope this this a 'correct' way to run the binaries compiled using m5threads through M5? I tried the same with M5's hello x86 binary and it worked fine. Looking at the gdb stack, and trace-flags, shows me that the instruction MOV_M_R seems to be getting 0 as the address. And this seems to happen after a bunch of correct address translations, not at the beginning of the simulation. I am not sure if this is a problem with the way I run the binary, an X86_SE issue or something else? I observed that the virtual address being 0 error I get is similar to an error discussed a few months back on the users forum? Thanks!
