Vortice.VulkanMemoryAllocator not working for iOS?

[JesperLykke]

I'm simply getting "Missing DLL exception: VMA". Do I have to do anything else but simply adding and using the Nuget. It works fine the Android part of the application.

Hi,
As you can see ios native libraries are not present

https://github.com/amerkoleci/Vortice.Vulkan/blob/main/src/Vortice.VulkanMemoryAllocator/Vortice.VulkanMemoryAllocator.csproj#L24

You can submit PR there with ios support if you can add it.

Thanks,

Amer

@amerkoleci I've just stumbled on this as well, trying to import my own static iOS vma libraries. I've posted a similar question in our previous discussion :)

@amerkoleci I've began switching to Vortice.VMA however I need to specify the LibName for the dll import.

ATM I am trying to switch to Vortice.VMA on iOS and I have a statically linked .a file, which I normally import using the extern P/Invoke methods, with a import signature of [DllImport("__Internal")]

However the VmaDllImporterResolver allows for overriding the entire import process - which I assume will only work for dynamic libraries?

I see that the code generator has some functionality for adding [DllImport ... so I assume it will generate those stubs - but is there something I am missing for using them?

@amerkoleci I was able to make it work using a Static Library version of the Vulkan Memory Allocator. However as far as I understand, these needs to be loaded using the "__Internal" path name when doing DllImport on iOS.

As DllImport uses a const I am unable to see how one would alter the setup in such a way to allow for dynamically changing the without having to edit the source and change the LibName.

I would not mind working on PR, however I am unable to see if this is even possible to alter without directly altering the source code before compilation?

Hi,
As I said i'm not expert on iOS development, so feel free to submit PR and try to make it work.

Thanks
