Problems running the very first application at the simulator

[Konstantinos Koukos]

Hello,

I have recently installed and configured gem5-gpu with the instructions provided in:
https://gem5-gpu.cs.wisc.edu/wiki/start

My python version is: Python 2.7.5+
gcc/g++ version 4.4.7 (Ubuntu/Linaro 4.4.7-2ubuntu2)
SCons v.2.3.0
SWIG Version 2.0.10 (Compiled with g++ [x86_64-unknown-linux-gnu]) / (Configured options: +pcre)

By running the following:
build/VI_hammer/gem5.opt ../gem5-gpu/configs/se_fusion.py -c ../benchmarks/rodinia/backprop/gem5_fusion_backprop -o 16

I get the following error:

gem5 Simulator System.  http://gem5.org

SystemError: NULL result without error in PyObject_Call

Could anyone please provide some more info about the problem???
(Most probably i either didn't build the benchmarks correctly or i am using incompatible version of something.)
My system is x86_64 as recommended.

Best Regards and thanks in advance.

The looks like a swig problem to me. Make sure that you are using the precise versions that we have found compatible with gem5-gpu. Those can be found http://goo.gl/S1ts6.

Hopefully that will fix the problem.

Rolling back swig and scons and rebuilding everything solved the problem.

Thanks a lot.
