# The following allows building Emulation station from local copy by using EMULATIONSTATION_SRC.
# The built makes symlinks to a local repository.
#
# One time setup:
# ---------------
# cd ~
# git clone https://github.com/JustEnoughLinuxOS/emulationstation.git
# cd emulationstation
# git submodule update --init
#
# Cleanup old files:
# ------------------
# DEVICE=RG351V ARCH=aarch64 ./scripts/clean emulationstation
#
# Build from local copy:
# ----------------------
# EMULATIONSTATION_SRC=~/emulationstation DEVICE=RG351V ARCH=aarch64 ./scripts/build emulationstation
#
# Run from the device:
# --------------------
# Copy ./emulationstation binary found in build.JELOS-<device>.aarch64/emulationstation-*/.install_pkg/usr/bin/
# Via ssh, run emulationstation with
# systemctl stop emustation
# chmod +x ./emulationstation
# ./emulationstation
