I wanted to confirm the version number of the gem5 that I was running, so I thought I could just try:

Build/X86/gem5.opt -B

Or

Build/X86/gem5.opt -version

Neither command sequence worked.  -version produced the error message no such option, and -B produced

AttributeError: module 'm5-defines' has not attribute 'gem5Version'

Is there an easy way to confirm the version number?

I tried it in my environment and got the same error as you, which makes me wonder maybe it's a bug. but you can still check the version of gem5 by running the command build/X86/gem5.opt -v.

More options for command line arguments can be found under src/python/m5/main.py, you can take a look at that file.

Best wishes!

Hoa,

Thank you, you were correct, the system put the version number in the output. If I try -v it acts like I requested –help.

Hi all,

It seems to be a bug in gem5.

You can run the gem5 binary without any arguments. The gem5 version is within the first few lines of the output.
