    Message : Re-land "Load entry points dynamically in tests and samples." Fixes the Android/ChromeOS/Fuchsia builds by using consistent EGL headers. This CL adds a dynamic loader generator based on XML files. It also refactors the entry point generation script to move the XML parsing into a helper class. Additionally this includes a new GLES 1.0 base header. The new header allows for function pointer types and hiding prototypes. All tests and samples now load ANGLE dynamically. In the future this will be extended to load entry points from the driver directly when possible. This will allow us to perform more accurate A/B testing. The new build configuration leads to some tests having more warnings applied. The CL includes fixes for the new warnings.

  • ANGLE EGL Headers

    The EGL headers ANGLE uses are generated using the Khronos tools but modified to include function pointer types and function prototype guards.

    Regenerating EGL.h

    1. Install Python 3 (not 2) with the lxml addon. You can do this using pip install lxml from your Python's Scripts folder.

    2. Clone https://github.com/KhronosGroup/EGL-Registry.git.

    3. Edit EGL-Registry/api/genheaders.py:

      1. Look for the section titled # EGL API - EGL/egl.h (no function pointers, yet @@@)
      2. Change genFuncPointers = False, to genFuncPointers = True,
      3. Change protectProto = False, to protectProto = 'nonzero',
      4. Change protectProtoStr = 'EGL_EGLEXT_PROTOTYPES', to protectProtoStr = 'EGL_EGL_PROTOTYPES',

    4. Set your working directory to EGL-Registry/api/.

    5. Run python genheaders.py -registry egl.xml EGL/egl.h

    6. The generated header will now be in EGL-Registry/api/EGL/egl.h. You can copy the header over to this folder.

    7. Also update scripts/egl.xml with the latest version from EGL-Registry/api/.
