Installing Xcode

Before you begin, you're going to need a Developer account with Apple. These are free and can be created by heading over to the Mac Dev Center, clicking the 'Register' link toward the top right hand corner and answering a few questions. If you already have an Apple ID, then you can link your developer account to that. Just enter it when it asks and continue through the registration process.

1. Install the latest version of Xcode that your OS X version supports. Consult the chart on the Xcode Wikipedia page.

   To find a specfic version of Xcode, go to the Downloads section of the developer center and run a search for that specific version (e.g.: Xcode 3.1.4) using the search box in the top left corner.

   Even though you can download Xcode itself through the App Store without a Developer ID, you still need one later to install the mobile device SDKs when you first run Xcode and to install the command line tools.

2. Download and install the Xcode command line tools (not needed for versions prior to OS X 10.7/Xcode 4.3.x):

   Starting with Xcode 4.3, Apple no longer includes the command line build tools within the standard Xcode distribution. In order to install them you have to open Xcode, go into its preferences dialog (Xcode -> Preferences in the menu bar or Command+,) and, in the 'Downloads' tab, click 'Install' next to 'Command Line Tools'. At this point you'll be prompted for your Developer ID. Just enter it and your password and it should be on its way.

Prerequisite Libraries

Install Homebrew. (On OS X 10.5, try Tigerbrew.)

Run the following in a terminal window:

brew install make sdl2 flac libvpx

You're all set! You can continue to the Building section.

Universal (Fat) Libraries

This section has not been tested for a long time and is not necessary when building for your own personal use!

First, install MacPorts. Make sure you have the correct version for your OS X version.

You then need to edit a couple of MacPorts' config files to make sure it builds what's needed correctly. At a terminal prompt, type:

sudo nano /opt/local/etc/macports/variants.conf

When prompted, enter your password and hit enter then add the following to the end of the file:

+universal
+no_x11

Then hold down Ctrl and press X to exit nano. You'll be asked if you want to save the file. Press 'Y'.

Now you have to make sure the architecturally relevant versions of things are being built by typing:

sudo nano /opt/local/etc/macports/macports.conf

Enter your password again if prompted and then scroll down until you get to the "universal_archs" line and make sure both i386 and x86_64 are in there if you have an Intel Mac (Core Duo, Core 2 Duo, Core i* or Xeon) and that i386 and ppc are there if you have a PowerPC (G4, G5) Mac.

Finally, install the prerequisites themselves:

sudo port install pkgconfig libsdl libsdl_mixer libsdl2 libsdl2_mixer zlib libpng libogg libvorbis flac libvpx

Again, entering your password if prompted. If any of these packages fail to build, remove it from the command and try again to make sure everything that can build has built.

Special notes for 10.5/Leopard users

osxbuild.sh assumes PowerPC support when run under Leopard. If you'd rather not build the PowerPC version, then call the script with the noppc parameter to prevent the PowerPC version from being built. If your Mac has a 64-bit capable CPU (Core 2 Duo or later), you may also want to enable the 64-bit build as well using the directions that follow.

The 64-bit build is also disabled on Leopard by default. If you wish to enable it and don't care about the PowerPC build then you have to call osxbuild.sh with the --build64=1 --buildppc=0 command line parameters and follow the Intel directions below. (64-bit here refers to x86_64, there's no equivalent 64-bit build for PowerPC so even if you have a 64-bit capable PowerPC processor, don't enable this unless you're trying to create a three-way universal binary as defined below).

If, on the other hand, you want to compile a three-way universal binary containing the PowerPC, x86 and x86_64 versions, things get a little more complicated. You not only have to manually enable the 64-bit build as outlined above, but you also have to make sure all but one of the dependency ports are compiled three-way universal as well. The procedure here is much the same as the directions above, but with a few exceptions: To start with, you need ppc, i386 and x86_64 all in your macports.conf universal_archs line. Use that to install everything but libvpx, and after you've finished installing those go back into macports.conf and remove ppc from the universal_archs before installing the libvpx port. You can put ppc back afterward if you want, but it's essential to remove it in order to build libvpx.

Building

Type gmake and hope for the best! For debug builds, run gmake RELEASE=0. If you want to use SDL 1.2 instead of SDL 2.0, you can append SDL_TARGET=1 to the make invocation.

Game Data

To play the game, the files you need are DUKE3D.GRP and DUKE.RTS. They, as well as any other data you have, such as the HRP, music packs, and mods, can be placed in the following locations, depending on the circumstances in which you want them to be used:

• ~/Library/Application Support/EDuke32/
• ~/.eduke32/
• EDuke32.app/Contents/Resources/

Play

Once everything is in place, you should be able to run the .app bundle. Enjoy!
