Building for OS X

You can use cmake to generate an Xcode project for PieNoon on OS X.

Version Requirements

These are the minimum required versions for building PieNoon on OS X:

• OS X: Mavericks 10.9.1.
• Xcode: 5.1.1 or newer
• Xquartz: 2.7.5 (xorg-server 1.14.4)
• cmake: 2.8.12 or newer
• Python: 2.7.*
• cwebp: 0.4.0 or newer (download from the WebP Precompiled Utilities)
• Ragel: 6.9 or newer

Before Building

• Install Xquartz.
• Reboot your machine. Rebooting sets the DISPLAY environment variable for Xquartz, which enables sample applications to run correctly.
• Download the libwebp archive for OS X from WebP Precompiled Utilities.
• Unpack cwebp to a directory on your system.
• Add directory containing cwebp to the PATH variable.
  • For example, if cwebp is installed in /home/dev/cwebp the following line should be added to the user's bash resource file ~/.bashrc.
    export PATH="$PATH:/home/dev/cwebp/bin"
• Install Ragel using package manager
  • e.g. brew install ragel
  • e.g. sudo port install ragel

Creating the Xcode project using cmake

The Xcode project is generated using cmake.

For example, the following generates the Xcode project in the pie_noon directory.

cd pie_noon
cmake -G "Xcode"

Building with Xcode

• Double-click on pie_noon/pie_noon.xcodeproj to open the project in Xcode.
• Select "Product-->Build" from the menu.

You can also build the game from the command-line.

• Run xcodebuild after generating the Xcode project to build all targets.
• You may need to force the generated_includes target to be built first.

For example, in the pie_noon directory:

xcodebuild -target generated_includes
xcodebuild

Executing the Game

• Select "pie_noon" in Scheme, for example "pie_noon-->My Mac 64-bit", from the combo box to the right of the "Run" button.
• Click the "Run" button.
