Building from source

Building guiscrcpy from source.

Local build

Building guiscrcpy locally (user-level), is easier than a system-wide installation

git clone https://github.com/srevinsaju/guiscrcpy.git --depth=1
cd guiscrcpy
python3 setup.py install --user

If ~/.local/bin is not on PATH, add it to your ~/.bashrc, ~/.zshrc

System-wide build (Linux only)

Installing a python package with sudo always messes up the system. As an alternative, as suggested by @tukusejssirs, a possible solution is to install it to the /opt on Linux.

git clone https://github.com/srevinsaju/guiscrcpy --depth=1
sudo python3 -m pip install . --prefix=/opt/guiscrcpy
echo "

TEST_PYTHONPATH=$(grep -c '/opt/lib/python3.8/site-packages' <<< '$PYTHONPATH')

if [ -e /opt/lib/python3.8/site-packages ]; then
    if [ '$TEST_PYTHONPATH' = '0' ]; then
	if [ '$PYTHONPATH' ]; then
	    export PYTHONPATH='$PYTHONPATH:/opt/lib/python3.8/site-packages'
	else
	    export PYTHONPATH='/opt/lib/python3.8/site-packages'
	fi
    fi
fi
"
>> ~/.bashrc

NOTE: Use sudo wisely, unless you have a proper reason to install guiscrcpy system-wide, DO NOT do it.
