You can also control whether to compile “debug” or “release” versions in this way (under the “Info” tab).

To specify runtime arguments, go to “Product” -> “Scheme” -> “Edit Scheme …” menu and add under “Arguments Passed On Launch'.

To compile, click on the arrow button near the top left (“Build and then run the current scheme”).

Move the mouse to “Preprocessor Macros” and click on “+” for Debug and Release builds, add desired definitions (RtMidi must be compiled with the _MACOSX_CORE_ preprocessor definition).

To specify preprocessor definitions, go to “Build Settings” in middle frame, click on “All”, then search for preprocessor.Remove the “main.cpp” default file from the project by right-clicking on it and selecting “Delete”.Add “midiout.cpp”, “RtMidi.h” and “RtMidi.cpp” to the project in this way. With the “Show the Project navigator” tab selected in the left frame, right-click on project directory that contains the default “main.cpp” file and choose “Add Files to mytest” (there is a checkbox to copy the files, rather than link to them if that is preferred).RtMidi requires the CoreMidi, CoreAudio and CoreFoundation frameworks. Under the “General” tab, specify any frameworks needed in the “Frameworks and Libraries” section.Double-click on project name in the left frame to bring up settings in the middle frame (might already be displayed).Provide a project name (I will assume “mytest”) and specify a location in your file system.Then select “Command Line Tool” and “Next”.After opening Xcode, select “create a new Xcode project”.The assumption in all of the following examples is that we are trying to compile a program called midiout.cpp, which exists in a directory together with the RtMidi.cpp and RtMidi.h files. In this section, I will provide very brief summaries of the steps necessary to get a sample RtMidi program setup and compiled on some of the most common platforms.

The learning curves necessary to start working in each vary quite a bit. There are many different IDEs available for different operating systems and programming languages. IDEs typically provide editors with color-coding of language keywords that can sometimes immediately identify improper syntax, as well as debugging functionality that is more difficult to manage from a command-line interface. That said, you may find it useful to use a Integrated Development Environment (IDE) for programming and compiling. Thus, simple programs created with RtMidi can be written and compiled with only a text editor and a command-line interface (such as the Terminal.app program in OS-X or MSYS/MinGW The RtMidi distribution is designed to work with GNU compilation tools such as automake, autoconf, configure and Makefiles run from command-line interfaces.
