The script for generating the vulkan_wrapper is based on the work done by @olvaffe for Hologram's dispatch table: https://github.com/LunarG/VulkanSamples/blob/master/Sample-Programs/Hologram/generate-dispatch-table
The wrapper is used to support applications that don't want to link directly against libvulkan.so, which is not present on Android before 7.0 (Nougat).
The wrapper only contains core functions and WSI extensions.
To regenerate the wrappers:
cd scripts pushd ../Vulkan-Headers/include/vulkan ../../../scripts/generate_vulkan_wrapper.py parse vulkan.h > parsed_header
Copy contents of parsed_header into generate_vulkan_wrapper.py between the sections that read:
# generated by "generate_vulkan_wrapper.py parse vulkan.h" # end of generated code
Then run the script:
popd ./generate_vulkan_wrapper.py ../common/vulkan_wrapper.h ./generate_vulkan_wrapper.py ../common/vulkan_wrapper.cpp clang-format -i vulkan_wrapper.h clang-format -i vulkan_wrapper.cpp
