# Generating vulkan_wrapper
|
||
|
|
|
||
|
|
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
