How to compile HelloWorld application included in skia?

How do I compile skia HelloWorld program?

I went through this guide - it doesn't mention how to build example/HelloWorld

The version I have checked out is: 

c7b263b603107acdb16b6570989e1ce5a2c7eb4e

I see mentions of it inside the .gn files but I am not sure how to invoke that specific item.

The HelloWorld program will be build as part of the normal Skia build process (Reference) for debug builds.

In the Skia source directory:

  • Sync the third-party dependencies with python2 tools/git-sync-deps

  • Generate the build files with bin/gn gen out/Debug.

    • If you run into problems with Python 2 vs 3 here (i.e. when it complains about syntax errors in the build script), you would have to set Python 2 as the default. Instructions on how to achieve this might vary depending on your setup. You could look e.g. here for an example approach (creating a temporary bin directory with symlinks python and python-config to /usr/bin/python2 and /usr/bin/python2-config, then prepending this temporary directory to the $PATH).

  • Start the build process with ninja -C out/Debug. This will build all targets including HelloWorld.

    • To only build HelloWorld (and its dependencies), you could directly invoke ninja -C out/Debug HelloWorld.

  • The resulting binary is in out/Debug/HelloWorld.
