About the Build Targets

DeSmuME for OS X may be built using several different configurations. Each build configuration is listed in an Xcode project as a "build target." The Xcode project files (provided with the DeSmuME source,) provide several build targets to suit your needs. Many build targets are similar to each other, and so they have been organized into the following categories, based on what the build target produces.


OS X App

These build targets produce a self-contained OS X application package (or "app bundle"). These builds use our official OS X frontend to run the DeSmuME emulator, and are designed for the debugging and testing of pre-release builds. These app bundles are compatible with OS X v10.6 or later. (Also compatible with OS X v10.5 if building from the Xcode 3 project).

Build Target Goals:

  • Fully featured.
  • Widest build compatibility with Xcode versions running different OS X versions.
  • Quick debug-and-test of code changes.

Advantages:

  • Can be built on machines running OS X v10.5 or later, and Xcode v3.1.4 or later.
  • Binaries can be configured to run in debug mode or in release mode.
  • Binaries can be configured for PowerPC or Intel compatibility.
  • Building the app is faster than the final release build.

Disadvantages:

  • Binary compatibility with OS X v10.5 requires Xcode 3 to build.


OS X App (dev+)

This build target is just like the normal OS X App build, except it enables additional debugging features, such as the GDB remote stub. This build is meant for developer usage.

Build Target Goals:

  • Fully featured, and includes additional debugging features.
  • Must be compatible with the latest version of Xcode running on the latest version of OS X.
  • Quick debug-and-test of code changes.

Advantages:

  • Can be built on machines running Xcode v4.6.3 or later.
  • Binaries can be configured to run in debug mode or in release mode.
  • Building the app is faster than the final release build.

Disadvantages:

  • Must be built on a machine running OS X v10.7 or later.
  • Due to the additional debugging features, performance will be slightly lower compared to the other builds.


OS X App (Final Release)

This build target is for producing final release versions of DeSmuME. These builds will use our official OS X frontend contained in an OS X app bundle, and are tuned for the fastest possible performance and the widest binary and OS compatibility.

Build Target Goals:

  • Fully featured.
  • Widest binary compatibility.
  • Widest OS compatibility.
  • Fastest performance.

Advantages:

  • Produces the fastest running binaries compared to all other build targets.
  • Produces a universal binary that supports both 32-bit and 64-bit.
  • Binaries are compatible with OS X v10.5 and later.

Disadvantages:

  • Must be built on a machine running the latest version of OS X and Xcode.
  • Building the app for release takes more steps than other builds.
  • Requires Xcode 3 to build.


OpenEmu Plug-in

These build targets produce a plug-in bundle that is compatible with the OpenEmu application (http://openemu.org/). These build targets exist to prove that our DeSmuME source code is modular enough to be adapted easily into other applications. In this case, the plug-in contains the DeSmuME emulator backend, while OpenEmu acts as the frontend that runs the emulator.

Build Target Goals:

  • Compatibility with OpenEmu.
  • Proving that the core source code is modular enough to be integrated with third-party frontends.

Advantages:

  • Compatible with OpenEmu.
  • Plug-ins are much smaller in size compared to full application builds.

Disadvantages:

  • Must be built on a machine running OS X v10.7 or later.
  • Binaries only run on machines with 64-bit Intel processors running OS X v10.7 or later.
  • The frontend is handled by a third-party application, which will not expose all of DeSmuME's features to the user.

Set Up the Build Environment

All DeSmuME build targets must be built using Apple's Xcode IDE. The Xcode project files, included in the desmume/src/cocoa directory of the source code, are supported for the following versions of Xcode:

Project File Name Supported Xcode Version
DeSmuME (Xcode 3).xcodeproj v3.1.4 (if running on Leopard); v3.2.6 (if running on Snow Leopard or later)
DeSmuME (Latest).xcodeproj v4.6.3 or later

Xcode Setup

Refer to the following conditions to determine which Xcode version you need to install.


You must use Xcode 3 if any of the following conditions apply:

  • You are running OS X v10.5 or v10.6.
  • You are building an OS X App that runs on OS X v10.5.
  • You are building an OS X App that runs on PowerPC processors.
  • You are building an OS X App for final release.


You must use Xcode 4 or later if any of the following conditions apply:

  • You are running OS X v10.7 or later.
  • You are building an OpenEmu Plug-in.
  • You are building an OS X App for final release.


Note: Xcode 3 is not compatible with OS X v10.10 Yosemite. If you require the use of Xcode 3, you will need to run it on an older version of OS X.


Download Xcode 3

You can download Xcode 3 from the Apple Developer Connection website. Note that before you can download anything from the ADC website, you must log in using an Apple Developer ID. Once you are logged in, you may use the provided download links to download Xcode 3.


If you do not have an Apple Developer ID, you can register one for free.

If you are not already logged in to ADC, you can log in by accessing the ADC Downloads page.

Once you are logged in to ADC, you can use the following download links for Xcode 3.


Download the Latest Version of Xcode

Downloading the latest version of Xcode is very easy! If you are running Lion or later and have any Apple ID, then you can download Xcode directly from the Mac App Store.


Uninstall Previous Versions of Xcode

We highly recommend that you uninstall any previous versions of Xcode before you begin your installation. Doing so will better guarantee that you will have a clean build environment for DeSmuME. The easiest method for uninstalling Xcode is to use the uninstall-devtools script, located in the Library folder of your Xcode installation.

Note: You do not need to uninstall any versions of Xcode that are v4.3 or later. These versions of Xcode are self-contained application packages, which do not conflict with other Xcode versions.

To uninstall Xcode, open Terminal and type the following command into the command line:

sudo /Developer/Library/uninstall-devtools -mode=all

Note: You must be logged into an Administrator account to use this command.

Note: This command assumes that Xcode was installed at the default location, /Developer. The path to the uninstall-devtools script may be different if you did not use the default location when installing Xcode from before.


Set Up Xcode 3

Note: If you do not require the build options that Xcode 3 provides, then you may skip this step. See the Xcode Setup section for more details.

After Xcode 3 is downloaded, you will have a .dmg disk image containing a package installer. Start the Xcode 3 installation by opening the installer, and follow the onscreen instructions until you get to the installation list.

Once the installation list is shown, do the following:

  • If you are planning on making legacy builds, select the Mac OS X 10.4 SDK.
  • If you are planning on installing the latest version of Xcode alongside Xcode 3, then deselect "System Tools" and "Essentials > iOS SDK". Since the latest Xcode will already have the newest version of the iOS SDK, installing the version included with Xcode 3 will be a waste of time and disk space.

Continue the installation as normal and let the installation finish.


Set Up the Latest Version of Xcode

When you download Xcode from the Mac App Store, Xcode should automatically install itself to the Applications folder once the download is complete. There are no additional steps. Pretty easy, right?


Download the DeSmuME Source Code

The DeSmuME source code is managed using Subversion (SVN) and is hosted on SourceForge. In this section, we describe some common methods for downloading the source code. (In reality, there are many methods for downloading the source code, but those methods are beyond the scope of this document.)


Download via SourceForge Web Interface

These instructions will download the DeSmuME source code from the SourceForge Web Interface using your web browser.

1. Follow this link to DeSmuME's SourceForge Web Interface: http://desmume.svn.sourceforge.net/viewvc/desmume/

2. Click "Download GNU tarball" to start the download.

3. Once the download completes, expand the tarball using your decompression program. (By default, you should be using OS X's built in decompressor. In this case, just open the .tar file to expand the tarball.)


Download via Command Line

These instructions will download the DeSmuME source code to your desktop.

1. Open Terminal.app.

2. In the command prompt, enter the following exactly as shown:

svn co https://desmume.svn.sourceforge.net/svnroot/desmume ~/Desktop/desmume

Note: If you want to change the destination directory to a directory other than your desktop, change the "~/Desktop/desmume" part to the directory of your choice.

3. At this point, the download should start. However, if instead there is a message about an untrusted certificate, enter the following exactly as shown:

p


Download via Xcode 4 Organizer

These instructions are for Xcode 4 users that wish to use the Organizer for downloading the DeSmuME source code.

1. Open Xcode.app.

2. Choose Window > Organizer.

3. In the Organizer window, click Repositories.

4. In the bottom-left corner, click the + button, then choose Checkout or Clone Repository.

5. In the Location field, enter the following exactly as shown:

https://desmume.svn.sourceforge.net/svnroot/desmume

6. After Xcode confirms that the host is reachable, click Checkout.

7. In the file navigation sheet, choose a folder to save the source code to, then click Checkout.


Build the DeSmuME Source

Regardless of which build target you will be using, you will need to use one of the Xcode project files provided with the DeSmuME source code. For most cases, you will want to build the latest revision. So from the source code folder, navigate to the "/trunk/desmume/src/cocoa" folder.

There should be two Xcode project files present in this folder:

  • DeSmuME (XCode 3).xcodeproj
  • DeSmuME (Latest).xcodeproj


OS X App Build

This is the quickest and easiest way to get started with using a pre-release build of DeSmuME.

Building Using Xcode 3

1. Open the "DeSmuME (XCode 3).xcodeproj" project file using Xcode 3.

2. In the Build Target menu (located in the upper-left corner of the project window), under Active Configuration, choose Release.

3. In the Build Target menu, under Active Target, choose one of the four build targets.

4. Choose Build > Build, and then wait for Xcode to finish building the app.

And you're done! The newly built app will be present in the "/trunk/desmume/src/cocoa/build/Release" folder.

Building Using the Latest Version of Xcode

1. Open the "DeSmuME (Latest).xcodeproj" project file using Xcode.

2. Choose Product > Scheme > DeSmuME (OS X App).

3. Click Run. This will build a Debug version of the app, which will automatically launch when finished.

4. After the app launches, go back to Xcode.

5. In Xcode, choose Product > Build For > Profiling.

6. Right-click the DeSmuME (Debug) app in the dock, and then choose Options > Show in Finder.

7. In the Finder window that appears, you should be in a folder named "Debug". Right-click the window title (which should read "Debug"), and then choose the "Products" folder underneath it.

8. Wait for Xcode to finish building the app.

9. In the Finder, from the "Products" folder, open the "Release" folder.

And you're done! The newly built app will be present in the "Release" folder. You may quit the DeSmuME (Debug).app if you want.

Note: You may want to create an alias to this folder so that it is easier to access in the future.


OS X App Dev+ Build

The steps here are similar to that of the normal OS X App build, but will produce the developer-oriented build instead. In addition, you must be using Xcode 4 or later to make this build.

1. Open the "DeSmuME (Latest).xcodeproj" project file using Xcode.

2. Choose Product > Scheme > DeSmuME (OS X App, dev+).

3. Click Run. This will build a Debug version of the app, which will automatically launch when finished.

4. After the app launches, go back to Xcode.

5. In Xcode, choose Product > Build For > Profiling.

6. Right-click the DeSmuME (Debug, dev+) app in the dock, and then choose Options > Show in Finder.

7. In the Finder window that appears, you should be in a folder named "Debug". Right-click the window title (which should read "Debug"), and then choose the "Products" folder underneath it.

8. Wait for Xcode to finish building the app.

9. In the Finder, from the "Products" folder, open the "Release" folder.

And you're done! The newly built app will be present in the "Release" folder. You may quit the DeSmuME (Debug, dev+).app if you want.

Note: You may want to create an alias to this folder so that it is easier to access in the future.


OS X App Build for Final Release

This is the process that we use for our official release builds. To make this build, you must meet the following requirements:

  • You must have both Xcode 3.2.6 (this specific version) and the latest version of Xcode installed.
  • You must be running the latest version of OS X. At the time of this writing, the latest version is v10.10 Yosemite.


1. Open the "DeSmuME (XCode 3).xcodeproj" project file using Xcode 3.

2. In the Build Target menu (located in the upper-left corner of the project window), under Active Configuration, choose Release.

3. In the Build Target menu, under Active Target, choose the build target "DeSmuME (OS X App; PowerPC Release Build)".

4. Choose Build > Clean All Targets.

5. In the Clean All Targets sheet, check all options, then click Clean, and then wait for the clean process to finish.

6. Choose Build > Build. This will make a new app called "DeSmuME (PPC).app" in the "/trunk/desmume/src/cocoa/build/Release" folder.

7. Open the "DeSmuME (Latest).xcodeproj" project file using the latest version of Xcode.

8. Choose Product > Scheme > DeSmuME (OS X App; v10.5 Leopard Release Build).

9. Choose Product > Clean, and then wait for the clean process to finish.

10. Choose Product > Perform Action > Generate Optimization Profile.

11. In the Generate Optimization Profile sheet, ensure that Use Run Action is the selected option, and then click Run.

12. Wait for Xcode to finish building the app. When Xcode finishes, DeSmuME.app will automatically launch.

13. Perform the recommended PGO exercises listed on this page: TBD

14. After all PGO exercises are complete, quit DeSmuME.app. Xcode should now report that it has generated an optimization profile.

15. In Xcode, choose Product > Build For > Profiling, and then wait for Xcode to finish.

And you're done! The newly built app will be present in the "/trunk/desmume/src/cocoa/build/Merged Release" folder.


OpenEmu Plug-in Build

The DeSmuME OpenEmu plug-in is used as an extension to the OpenEmu application. Installing the plug-in involves building OpenEmuBase.framework from source, then moving the framework to the desmume/src/cocoa/openemu directory, then building the plug-in from source, and then finally placing the plug-in into the ~/Library/Application Support/OpenEmu/Cores folder.


You can download the OpenEmu SDK source code from here:


Building and installing OpenEmuBase.framework from source

1. Open the "OpenEmu-SDK.xcodeproj" project file using the latest version of Xcode.

2. Choose Product > Scheme > OpenEmuBase.

3. Click Run. This will build a Debug version of the framework.

4. After the build finishes, choose Product > Build For > Profiling. This will start building the Release version of the framework.

5. In the Xcode sidebar, expand the Products folder. This should show "OpenEmuBase.framework".

6. Click "OpenEmuBase.framework", and then choose File > Show in Finder.

7. In the Finder window that appears, you should be in a folder named "Debug". Right-click the window title (which should read "Debug"), and then choose the "Products" folder underneath it.

8. Wait for Xcode to finish building the Release version framework.

9. In the Finder, from the "Products" folder, open the "Release" folder.

10. Move OpenEmuBase.framework into the desmume/src/cocoa/openemu directory.

Building the OpenEmu plug-in

Note: In order to build the OpenEmu plug-in, it is mandatory that OpenEmuBase.framework is present in the desmume/src/cocoa/openemu directory. Otherwise, the build will fail due to missing frameworks.

1. Open the "DeSmuME (Latest).xcodeproj" project file using the latest version of Xcode.

2. Choose Product > Scheme > DeSmuME (OpenEmu Plug-in).

3. Click Run. This will build a Debug version of the plug-in.

4. After the build finishes, choose Product > Build For > Profiling. This will start building the Release version of the plug-in.

5. In the Xcode sidebar, expand the Products folder. This should show the "DeSmuME.oecoreplugin" bundle.

6. Click "DeSmuME.oecoreplugin", and then choose Show in Finder.

7. In the Finder window that appears, you should be in a folder named "Debug". Right-click the window title (which should read "Debug"), and then choose the "Products" folder underneath it.

8. Wait for Xcode to finish building the Release version plug-in.

9. In the Finder, from the "Products" folder, open the "Release" folder.

10. Choose New > New Finder Window.

11. With the new Finder window selected, choose Go > Go To Folder.

12. In the drop-down sheet, in the "Go to the folder" text field, enter the following exactly as shown:

~/Library/Application Support/OpenEmu/Cores

13. Move the DeSmuME.oecoreplugin bundle from the Release folder into the Cores folder.

And that's it! The DeSmuME OpenEmu plug-in should now be installed. You should now be able to run NDS ROMs from within OpenEmu.app.
