Hi,
I tried following previous archived threads which said the solution to this problem was to provide
the path to PYTHON_CONFIG and not using a conda environment.
I am not using a conda environment and am providing the path in the scons
command:
scons ./build/ARM_MESI_Three_Level/gem5.opt PYTHON_CONFIG=/usr/bin/python-config
scons: Reading SConscript files ...
Mkdir("/data/anurag/gem5-public/build/ARM_MESI_Three_Level/gem5.build")

Error: Can't find a working Python installation
I have been able to build gem5 on this very machine before, I’m not sure what changed between then
and now. Can someone help me debug this?
To pass an environment variable into a program, write your command line this
way:
PYTHON_CONFIG=/usr/bin/python-config scons ./build/ARM_MESI_Three_Level/gem5.opt
or else do this first:
export PYTHON_CONFIG=/usr/bin/python-config
BUT ... at least in my setup, python-config does not exist, yet all works fine.
Is python accessible through PATH? That's what I would check first. If you're
on bash, then "type python" will show you.
