Mac OS X

Prerequisites

Make sure the following have been installed:

• XCode (Apple's development environment): required
  • publicly available at http://developer.apple.com/xcode/
  • add the optional Unix Tools to the install so you get the make command line tool.
• Chromium depot_tools: required to download the source and dependencies
  • http://www.chromium.org/developers/how-tos/depottools

Check out the source code

See the instructions here.

Generate XCode projects

We use the open-source gyp tool to generate XCode projects (and analogous build scripts on other platforms) from our multiplatform "gyp" files.

Before building, make sure that gyp knows to create an XCode project or ninja build files. If you leave GYP_GENERATORS undefined it will assume the following default:

GYP_GENERATORS="ninja,xcode"

Or you can set it to ninja or xcode alone, if you like.

You can then generate the Xcode projects and ninja build files by running:

./gyp_skia

Build and run tests from the command line

ninja -C out/Debug dm
out/Debug/dm

The usual mode you want for testing is Debug mode (SK_DEBUG is defined, and debug symbols are included in the binary). If you would like to build the Release version instead:

ninja -C out/Release dm
out/Release/dm

Build and run nanobench (performance tests)

In this case, we will build with the "Release" configuration, since we are running performance tests.

ninja -C out/Release nanobench
out/Release/nanobench [ --skps path/to/*.skp ]

Build and run SampleApp in the XCode IDE

• Run gyp_skia as described above.
• In the Finder, navigate to $SKIA_INSTALLDIR/trunk/out/gyp
• Double-click SampleApp.xcodeproj ; this will launch XCode and open the SampleApp project
• Click the “Build and Run” button in the top toolbar
• Once the build is complete, you should see a window with lots of shaded text examples. To move through the sample app, use the following keypresses:
  • right- and left-arrow keys: cycle through different test pages
  • 'D' key: cycle through rendering methods for each test page
  • other keys are defined in SampleApp.cpp’s SampleWindow::onHandleKey() and SampleWindow::onHandleChar() methods
