Compiling Zandronum on Mac

Install dependencies

Zandronum needs certain tools and development files in order to compile:

Required
- Xcode
- CMake
- Mac OS SDK
- SDL2 with SDL 1.2 Compatibility
- GLEW
- FMOD Ex 4.44.64
- Python3 (It's already on the Mac)
- Openssl (for Zandronum 1.3 or later)
- SQLite (for Zandronum 1.3 or later)
- TortoiseHg (needed in order to download the source and compile in commit meta data)
Optional
- Fluidsynth (For Midi Device)
- zlib (Zandronum has a copy of it and will be statically compiled in if not found)
- libbzip2 (possibly static)
- libjpeg (possibly static)
- HomeBrew or Macports (Not recommended for building using M1 or M2 (ARM64) CPU)
- Rosetta 2 (for building X86_64 binaries using M1 or M2 (ARM64) CPU)

Installing Xcode

There are 3 ways to install Xcode:

Command line Tools

Open Terminal.app and paste this command:

xcode-select --install

This'll pop up:

Install it. (Caution: it's big so make sure you got enough space)

App Store (if you have an newer system)

Xcode (Click the link, it'll go straight to the App Store)

Apple developer (if you have an older system)

https://developer.apple.com/download/all/ (Sign in is required. It includes Command line Tools as well)

Installing from HomeBrew or Macports

HomeBrew (MacOS 10.15 - Latest)

brew install jpeg-turbo fluid-synth openssl sdl2 sdl12-compat

MacPorts (Legacy MacOS)

sudo port install jpeg-turbo fluid-synth openssl sdl2 sdl12-compat

Installing CMake GUI and TortoiseHG

Download CMake and TortoiseHG

Open up the DMG and copy them into Applications (or drag them).

Create zandronum_build directory

Open Terminal.app and paste this command:

mkdir -pv ~/zandronum_build

Compiling SDL12-Compat

If you already have this installed using HomeBrew or Macports. Please skip this section.

Create a directory like this:

cd  ~/zandronum_build && mkdir -pv sdl_pack

Download SDL2 and SDL 1.2 Compatibility and extract them into it.

Clone it:

git clone https://github.com/libsdl-org/sdl12-compat.git && git clone https://github.com/libsdl-org/SDL.git

Click on the CMake app that you added into Applications, it'll give you a warning that you downloaded a third party app on Mac, just hit OK.

Click Browse Source, choose where you put SDL12-Compat, then click Open.

It's better if you build it inside the source, so do the same in Browse Build. Add a new folder into SDL12-Compat called Build.

When you click Configure it'll popup a window, choose "Unix Makefiles" (It's faster than using Xcode type) and click Done.

Configure CMake like the image below:

Make sure you disable SDL12TESTS as we don't need it and make the default architecture x86_64 because we are not using ARM64 until further releases.

Then check Advanced to display the SDL2 Section.

Configure only SDL_INCLUDE_DIR.

Click Generate and then compile, it'll give you 2 files.

cd  ~/zandronum_build/sdl_pack/sdl12-compat/build/ && make

TortoiseHG

Open TortoiseHG.app

Go to File -> Clone Repository

Add this line it to the source line:

https://hg.osdn.net/view/zandronum/zandronum-stable

Browse where you put zandronum_build in:

It should be like this:

Click Clone.

Stable

if you are looking for the Stable version go to Repository -> Update

It should pop up like this:

Select ZA_3.1 from the dropdown then click Update.

You might need to add this patch for bundling an app: (If it does give you the text file, download it by Right clicking and selecting Save as.)

https://osdn.net/downloads/users/39/39032/Appbundle.patch/

To add the patch:

Go to Repository -> Import Patches

Browse to the Appbundle.patch then click Open and then Import. (It won't include the icon for Mac OS for some reason.)

https://osdn.net/downloads/users/39/39033/zandronum.icns/

Put this icon where you put the source into:

/src/sdl/

Compiling Zandronum

Open the CMake app again.

This is a lot because you must compile most of the dependencies before you can do this next part, so read the readme on each source codes. Homebrew and MacPorts are fine.

So firstly Browse Source and Build like you did with SDL12-Compat.

Click Browse Source, choose where you put SDL12-Compat, then click Open.
It's better if you build it inside the source, so do the same in Browse Build. Add a new folder into SDL12-Compat called Build.
When you click Configure it'll popup a window, choose "Unix Makefiles" (It's faster than using Xcode type) and click Done.

If it shows an error that means they couldn't find the rest. So you need to go through each dependency to find the directories and files then hit Generate.

This is how it should look:

If you only see SDL_INCLUDE_DIR, click Add Entry and type in SDL_LIBRARY then browse for the Dylib.

Once you've done everything, compile.

cd  ~/zandronum_build/zandronum-stable/build/ && make -j(nproc)

Once the compile is finished, all that's left to do is to add the SDL2 framework into the Frameworks directory inside the app bundle by Right clicking and selecting Show package content.

There you have it, just drag the bundle into the applications, and it should be good to go.
