Build QEMU on Fedora 40

Problem

Recent ran into an error using QEMU 8.x on Fedora 40 (via dnf install) and needed to upgrade to the latest QEMU (9.1.x at the time of writing). Here is the process I followed to get up to date.

Code

#!/bin/bash -l

set -eo pipefail

# Preflight checks

if [[ $LOG_LEVEL == "TRACE" ]]
then 
    set -x
fi

if [[ $(which python) ]]
then
    echo "ERR: Python >= 3.11 required."
    exit 1
fi

## Remove if exists

dnf remove -y qemu || true
dnf list --installed | grep qemu
if [[ $? != "1" ]]
then
    echo "ERR: QEMU install still exits. It should not.
    exit 1
fi

## Install Dependencies

sudo dnf install -y \
    bison \
    flex \
    ninja-build

pip install --user \
    sphinx==5.3.0 \
    sphinx_rtd_theme==1.1.1

git clone https://gitlab.com/qemu-project/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
# The build process time depends on compute resources. It can take a long time on less than powerful machines.
make

After QEMU 9.1.x was built successfully.
