Linux ===== Quickstart ---------- # Install depot_tools (this provides ninja and git-cl). git clone 'https://chromium.googlesource.com/chromium/tools/depot_tools.git' export PATH="${PWD}/depot_tools:${PATH}" # Get Skia. git clone 'https://skia.googlesource.com/skia' cd skia # Install Dependencies (may require sudo). tools/install_dependencies.sh # Sync, Config, and Build. bin/sync-and-gyp ninja -C out/Debug dm SampleApp # Run DM, the Skia test app. out/Debug/dm # Run SampleApp. out/Debug/SampleApp # Run nanobench, the Skia benchmarking tool. ninja -C out/Release nanobench out/Release/nanobench Prerequisites ----------------------------------------- On a Ubuntu 12.04 (Precise) or Ubuntu 14.04 (Trusty) system, you can run `tools/install_dependencies.sh`, which will install the needed packages. On Ubuntu 12.04, you will need to install the`ninja` build tool separately, which comes with Chromium's `depot_tools`. To contribute changes back to Skia, you will need `git-cl`, which comes with Chromium's `depot_tools`. (If you use another Linux distribution, please consider contributing back instructions for installing the required packages — we can then incorporate that knowledge into the `tools/install_dependencies.sh` tool.) Make sure the following have been installed: * [Chromium depot_tools](http://www.chromium.org/developers/how-tos/depottools) * A C++ compiler (typically GCC or Clang) **build-essential** or **clang-3.6** * Python 2.7.x: **python2.7-dev** * The FreeType and Fontconfig font engines: **libfreetype6-dev** and **libfontconfig1-dev** * Mesa OpenGL utility library headers: **libglu1-mesa-dev** * Mesa headers: **mesa-common-dev** * GL, such as **freeglut3-dev** Check out the source code ------------------------- Follow the instructions [here](../download) for downloading the Skia source. Notes ----- 1. On 32-bit Linux (when `uname -m` is *not* `x86_64`), you will have to explicitly specify the architecture: GYP_DEFINES='skia_arch_type=x86' python bin/sync-and-gyp 2. By default, many Linux systems use gcc by default. To use clang you will need to [set the CC and CXX environment variables](/user/tips#gypdefines). Generate build files -------------------- See [this page for generating build files and run tests](desktop).
