Using the section attribute -fno-extern-tls-init option. in bytes. If and earlier, for every constexpr function and function template, To use the DispatchLoaderDynamic as the default dispatcher (means: you don't need to explicitly add it to every function call), you need to #define VULKAN_HPP_DISPATCH_LOADER_DYNAMIC 1, and have the macro VULKAN_HPP_DEFAULT_DISPATCH_LOADER_DYNAMIC_STORAGE exactly once in your source code to provide storage for that default dispatcher.

In the 1D array, we don't need to specify the size of the array if the declaration and initialization are being done simultaneously. Due to that Vulkan-Hpp does not enable implicit conversion for 32-bit platforms by default and it is recommended to use a static_cast for the conversion like this: VkImage = static_cast(cppImage) to prevent converting some arbitrary int to a handle or vice versa by accident.
