The error happens when I use Ariel and Pintool #857

Closed liuyidinguh closed 4 years ago

New Issue for sst-elements

1 - Detailed description of problem or enhancement When I want to use Ariel and pintool, the error shows: FATAL: ArielComponent[arielcpu.cc:461:forkPINChild] Launching trace child failed! Child Exited with status 255 FATAL: ArielComponent[arielcpu.cc:461:forkPINChild] Launching trace child failed! Child Exited with status 255 I have tried to use both the example of Pintool and Pintool I wrote, which have been successfully compiled with the GCC 4.9.2, Pin 2.14 and SST/6.1.0. I think it may be resulted from the injection failure between Pintool parent process and child application process. 2 - What Operating system(s) and versions GNU/Linux bash-4.1

Thanks for helping me!

Hi thanks for reporting this issue. Few questions:

Does your application run outside of Ariel successfully?

Can you "ldd" on your binary and reply with the output to this issue? This helps us identify possible library conflicts

Also, can we get the Ariel section of your Python input to SST?

Thanks! We won't be able to look at this until a little later this week.

Yes, the application runs successfully outside, and when I use the example of application in SST(stream), the error is same. Here is some additional error information: SST Fatal Backtrace Information: 0 : sst(_ZNK3SST6Output5fatalEjPKcS2_jS2_z+0x2aa) [0x496ada] 1 : /project/xfu/apps/sstelements-6.1.0/lib/sst-elements-library/libariel.so(_ZN3SST14ArielComponent8ArielCPU12forkPINChildEPKcPPcRSt3mapISsSsSt4lessISsESaISt4pairIKSsSsEEE+0x505) [0x2b85d12de8e5] 2 : /project/xfu/apps/sstelements-6.1.0/lib/sst-elements-library/libariel.so(_ZN3SST14ArielComponent8ArielCPU4initEj+0x61) [0x2b85d12dea31] 3 : sst(_ZN3SST10Simulation10initializeEv+0x89) [0x49cbe9] 4 : sst() [0x44e283] 5 : sst(main+0x1138) [0x45d388] 6 : /lib64/libc.so.6(__libc_start_main+0xfd) [0x362961ed1d] 7 : sst() [0x44d9cd]
