Compiler Setup (Xcode)

Xcode notes

Although Raknet is cross-platform, not all of the samples provided will compile/run on Mac OS X or iOS. Here I'll show you how to compile Raknet for Mac OS X and iOS, along with one of the samples for testing

Compiling as a static library for Mac OS X

Create an empty workspace

Create a folder named RakNetTests, and then create a new empty Workspace. Name it RakNetTests, and save it inside the new folder

Create the RakNet static library project

Using File->New->New Project, create a new Mac OS X C/C++ library project

Name it RakNet and use the following options:

Save it inside the same folder as the workspace
Using Finder, copy RakNet's source code (Source folder) to where RakNet project file was created
Right-click the RakNet project, and select Add Files to "RakNet"... , and select the new Source folder you should have in the same folder as the RakNet Project file. Use the following options:

This should create a Source group, like this:
The files inside the cat folder aren't supposed to be compiled, so remove the Source/cat group from the project files.
When prompted for the deletion method, pick Remove References Only.
Build Raknet using Product->Build
You should get a successful compilation.

Testing the static library

A simple sample...

For testing, we're going to use the sample "Chat Example" provided with the Raknet. You can find it the "Samples/Chat Example" folder. This sample has 2 source files, named "Chat Example Server.cpp" and "Chat Example Client.cpp". We are going to create two projects from those files (one project for the Server, and another for the Client).

Inside the folder where you have your workspace, create another folder named Samples, and copy "Chat Example Server.cpp" and "Chat Example Client.cpp" into that folder.

The server

Create a Command Line Tool project for the Server:

In the next window where it asks for the options for your new project, name it ChatExampleServer, leave Type as C++, and "Use Automatic Reference Counting" unchecked.
Save the project inside your Samples folder.
Inside the newly created ChatExampleServer, you should have a group named ChatExampleServer. Delete the main.cpp you'll find inside that group, and add the "Chat Example Server.cpp" file
Specify where to look for the RakNet header files, by changing the Build Settings of the ChatExampleServer project. This can be done in the Header Search Paths option, under the Search Paths section:

If your folder structure is exactly the same as the one used for this tutorial, then the search path should be what you see in the above image. If not then you need to adjust it accordingly.
NOTE: The search path is relative to the project file's location.
Link ChatExampleServer project with our RakNet static library, by going to Build Phases, section Link Binary With Libraries, clicking the '+' button and picking our RakNet library as shown:
You should be able to successfully build and run the Server now.

The Client

The steps to create the client project are the same as the ones for the Server:

Create a "Command Line Tool" project, and name it ChatExampleClient
Delete the file main.cpp and add the file "Chat Example Client.cpp"
Change the C/C++ compiler to LLVM GCC
Set the header search paths
Add RakNet library to the list of libraries to link with.

Running the sample

You should now have 2 products ready to run (ChatExampleClient and ChatExampleServer). You can run one of them from inside Xcode, and run the other externally by right-clicking on it and selecting "Open With External Editor".

Compiling as a static library for iOS

Compiling Raknet as a static library for iOS is essentially the same as for Mac OS X.
You can create a new project for the iOS library, or you can just create another Target for your Mac OS X static library project, and change what SDK to use:

You can find some iOS samples in the Samples/iOS folder.
