Hi gem5-users, I've got two related questions: Question 1: I implemented a set of functions in a simple non-SimObject C++ source and header (configuration.hh/configuration.cc) that contains some functionality that I intend to call from my SimObject. My SConscript file looks like this: Import("*") SimObject("Generator.py", sim_objects=["GeneratorSimObject"]) Source("generator.cc") Library('configuration', ['configuration.cc']) Is this best practice to add non-SimObjects to gem5? Question 2: The above SConscript builds my project successfully, however when I include configuration.hh in my SimObject source, generator.cc, I get the error: expected initializer before 'namespace' 13 | namespace: gem5 On line 13 of generator.cc. I cannot for the life of me figure out what's going wrong. BTW, I'm being naughty and using #pragma once. I hope that's not the problem. Regards, - Olumide

Turns out a semi-colon was missing at the end of the configuration.hh. So that was an easy fix. SConscript can now build my project, however there is a linker error/undefined reference to the function that I am trying to call from configuration.hh. Hopefully this will be fixed by the following addition to my SConscript: configuration_src = ['configuration.cc'] configuration_lib = env.Library('configuration', configuration_src) env.Append(LIBS=[configuration_lib]) Not sure if this the best way to go about it tho.
