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 theninja 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:
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
QT4, used by the Skia Debugger: libqt4-dev
Follow the instructions here for downloading the Skia source.
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
By default, many Linux systems use gcc by default. To use clang you will need to set the CC and CXX environment variables.
