No build directory in /PIMSim/GEM5Simulation/gem5, unable to build

[anaarduengo]

If you try to build gem5 to run the simulator in full-system mode, in the README file they say:

This is the gem5 simulator which support PIM features.

Recommand g++/gcc version is 4.8.1

To start:

sh hellopim.sh

Then in the hellopim.sh file, the first two lines are:

echo "\033[33m(PIMSim): Building gem5... \033[0m"
scons -j16 build/X86/gem5.opt

But there is not build directory in the project. I have tried to copy the build directory there is in the original gem5, but as you could expect it is not working because it is not adapted to this simulator. It is giving me the following error:

invalid debug flag 'PIM'

Is this correct? Thanks in advance!

change directory to /PIMSim/GEM5Simulation/gem5 and next run:
sh hellopim.sh
