'gem5 build fails with " Embedded python library 3.6 or newer required, found 2.7.17."

I cannot build gem5, when I build gem5,the terminal shows " Embedded python library 3.6 or newer required, found 2.7.17.".However,when I check my python version, I find my python version is 3.6.

python --version

Python 3.6.7

python gem5

The gem5 build environment does not use your user environment. This means your custom values for PATH and other environment variables won't be set. My intuition is your Python 3 installation is pointed to by one of your custom values. In the absence of these, gem5 uses the Python system installation, which is Python 2 in your case.

You can instruct the gem5 build process to use a particular Python installation through the PYTHON_CONFIG build variable. To use your Python 3 installation:

scons PYTHON_CONFIG=python3-config ...

Try the below commands. It worked for me.

sudo apt-get update

sudo apt-get install python-dev scons m4 build-essential g++ swig

sudo apt install python3-pip

pip3 install scons

scons build/X86/gem5.opt -j8

On Ubuntu 20.04, or related Linux distributions, you may install all these dependencies using the command below:

sudo apt install build-essential git m4 scons zlib1g zlib1g-dev \
    libprotobuf-dev protobuf-compiler libprotoc-dev libgoogle-perftools-dev \
    python3-dev python-is-python3 libboost-all-dev pkg-config
