Dear Nayana, Thank you for your email.
Could you please go to the folder created by run_job, and insert the following line into start.simics file: WAITFORSIGCONT=yes After that, invoke the trace simulator manually in a terminal, it will output the id of the process so you can attach gdb to it and type “c” in the gdb commandline. Please feel free to contact us if GDB’s output is not illuminating. Best regards, Dmitrii On 12 Dec 2017, at 19:59, Nayana Prasad Nagendra <[email protected]<mailto:[email protected]>> wrote: Hi all, I am getting segmentation fault while executing run_job command on Flexus. I am using Simics-3.0.28 with Solaris-10 OS, Boost 1.33.1, Flexus 4.1, Ubuntu 12.04. I could successfully build Flexus and run prepare-test-app (following the instructions in Flexus Getting Started guide). However, when I run the run_job command ("run_job -postprocess "$SCRIPT_ROOT/postprocess_ckptgen.sh flexpoint 28 test_app" -cfg trace -run flexpoint -local -ckpt-gen UP.Trace flexus_test_app_v9"), I am getting segmentation fault. I have attached the complete output below. I also read through some messages in the mail list and followed steps mentioned in "https://www.mail-archive.com/[email protected]/msg00469.html"; to make sure I have the same version of libstdc++ in Simics path. Even after those changes, I am still having the same issue. Any help in this regard is much appreciated.
