Re: [gem5-users] Getting a C++ program (with tensorflow) to work.
Hi, I'd expect libloader.so file to be a library and that's suspicious... Besides that, I have had much more success running complex workloads on FS mode than in SE mode (however, I've worked mostly with ARM architecture). I'd advise you try that.

Re: [gem5-users] Getting a C++ program (with tensorflow) to work.
How to build that program step by step? What are the versions of your OS, compiler and gem5 revision? Are you able to run other shared libraries fine? Are you wearing a tie? Use GDB step debugging or tracing to find out at which instruction / point of code it is blowing up.
