Hello all,

So I’m trying to build gem5 on a new machine and I get the following error.

I have experience with building gem5 but on this machine I can’t figure out 
what the problem is. Did anyone faced the same issue before?

The gem5 version I use is  21.1.0.2

GCC version is 11.3

Python 3.10.4

Thank you in advance,
Ioannis Constantinou.
