Building prboom-plus on macOS

build-prboom-plus-macos.sh

# Kudos to Ribbiks from Doomworld forums, whose post helped me figure out how to get prboom built in the first place.

# Install Xcode from AppStore (you can skip this step if you will be building PrBoom+ without OpenGL support)

# Run Terminal and proceed with the following steps.

# Install Xcode command line tools
xcode-select --install

# Install homebrew (you will need to enter your password for installation)
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

# Install automake, autoconf, and libraries needed to build prboom-plus
brew install automake autoconf sdl2 sdl2_net sdl2_image sdl2_mixer libpng pkg-config

# (Optional) Install additional music playback libraries
brew install mad dumb fluid-synth portmidi

# Get prboom-plus source code from the official PrBoom+ repository
svn checkout https://svn.prboom.org/repos/branches/prboom-plus-24/prboom2/

# Enter PrBoom+ directory
cd prboom2

# Configure build step 1
./bootstrap # Re-run this if you installed additional packages after running it the first time

# Configure build step 2.a (to build with OpenGL support)
./configure

# Configure build step 2.b (to build without OpenGL support)
#./configure --disable-gl

# Build PrBoom+
make

# Install PrBoom+ to default location (installs to /usr/local/games/)
sudo make install
