On 41 Ubuntu 12.04, you will need to install the`ninja` build tool separately, which 42 comes with Chromium's `depot_tools`. 43 44 To contribute changes back to Skia, you will need `git-cl`, which 45 comes with Chromium's `depot_tools`. 46 47 (If you use another Linux distribution, please consider contributing back 48 instructions for installing the required packages we can then incorporate 49 that knowledge into the `tools/install_dependencies.sh` tool.) 50 51 Make sure the following have been installed: 52 53 * [Chromium depot_tools](http://www.chromium.org/developers/how-tos/depottools) 54 55 * A C++ compiler (typically GCC or Clang) **build-essential** or **clang-3.6** 56 57 * Python 2.7.x: **python2.7-dev** 58 59 * The FreeType and Fontconfig font engines: **libfreetype6-dev** and 60 **libfontconfig1-dev** 61 62 * Mesa OpenGL utility library headers: **libglu1-mesa-dev** 63 64 * Mesa headers: **mesa-common-dev** 65 66 * GL, such as **freeglut3-dev** 67 68 * QT4, used by the [Skia Debugger](/dev/tools/debugger): **libqt4-dev** 69 70 Check out the source code 71 ------------------------- 72 73 Follow the instructions [here](../download) for downloading the Skia source. 74 75 Notes 76 ----- 77 78 1. On 32-bit Linux (when `uname -m` is *not* `x86_64`), you will have to 79 explicitly specify the architecture: 80 81 <!--?prettify lang=sh?--> 82 83 GYP_DEFINES='skia_arch_type=x86' python bin/sync-and-gyp 84 2. By default, many Linux systems use gcc by default. To use clang you will 85 need to [set the CC and CXX environment variables](/user/tips#gypdefines). 86 87 Generate build files 88 -------------------- 89 90 See [this page for generating build files and run tests](desktop). 91
