New Setup

[Brian Beuken]

I have had a lot of issues with some updates recently but I've managed to resolve most of them..

If you are using your Pi for the 1st time remember you need to run the setup script at least one time. It will install all the libs needed throughout the book. It will be attached to all Pi projects but here is the most updated version.

Code:

#!/usr/bin/env bash
#
# Dev environment setup � safe to re-run.
# Re-running updates the git repos to their latest version and refreshes apt packages.

# --- helper: clone a repo if it's missing, otherwise update it to the latest version ---
clone_or_update() {
    url="$1"
    dir="$2"
    if [ -d "$dir/.git" ]; then
        echo "Updating $dir (pulling latest)"
        git -C "$dir" pull --ff-only
    else
        echo "Cloning $dir"
        git clone "$url" "$dir"
    fi
}

echo installing
echo installing cmake
cd "$HOME"
sudo apt update                 # refresh the package index so re-runs get the latest apt versions
sudo apt install cmake -y
echo

# stb
echo installing STB
clone_or_update https://github.com/nothings/stb.git "$HOME/stb"
echo STB install done

# GLM
echo installing GLM
clone_or_update https://github.com/g-truc/glm.git "$HOME/glm"
echo GLM Install done

echo "Installing Jeremiah Audio"
clone_or_update https://github.com/3dgep/Audio.git "$HOME/Audio"

cd "$HOME/Audio"
rm -rf build                    # start clean so Debug AND Release rebuild correctly every run
mkdir -p build
cd build

# ---- Debug ----
cmake -DCMAKE_BUILD_TYPE=Debug ../
cmake --build .
mkdir -p ../lib/Debug
mv ../lib/*.a ../lib/Debug/
echo "debug audio files added"

# ---- Release ----

cmake -DCMAKE_BUILD_TYPE=Release ../
cmake --build .
mkdir -p ../lib/Release
mv ../lib/*.a ../lib/Release/
echo "release audio files added"

cd "$HOME"
