Python incompatibility issue when building gem5 v20.1.0.4 for SPEC CPU 2017

[m-ert]

I am new and Im following the SPEC tutorial which requires gem5 v20.1.0.4 and Im getting Python version related errors when trying to build via scons build/X86/gem5.opt -j8.

On my Ubuntu 24.04 system, I had python 3.12 by default and got the following error saying there are deprecated and removed stuff such as imp module:

...
line 285:
    exec(compile(scriptdata, scriptname, 'exec'), call_stack[-1].globals)
  File "/home/mhsn/gem5-resources/src/spec-2017/gem5/build/X86/SConscript", line 45:
    import imp

Tried building with Python 3.12, 3.10, 3.8, 3.4 using virtual environment but all of them gives errors.

Errors look all similar and seem to be some python version incompatibility.

gem5 v24.0.0.1 builds and works fine. I could not find the documentation for running gem5 20.1.0.4. Do I need to downgrade Ubuntu?

gem5 20.1 is no longer supported. I would suggest trying to use 24.0 with the tutorial. In fact. gem5art isn't well supported anymore either. It has been migrated to gem5-resources. This page may be more helpful: https://github.com/gem5/gem5-resources/tree/stable/src/spec-2017
