I’m trying to recompile SDL2 with wayland video support, but i’m hitting an error

/opt/UnrealEngine/Engine/Source/ThirdParty/SDL2/SDL-gui-backend/src/video/x11/SDL_x11vulkan.h:23:10:
fatal error: vulkan/vulkan.h: No such
file or directory include

      ^~~~~~~~~~~~~~~~~

Is there any setup prior to running build.sh under the Engine/Source/ThirdParty/SDL2?

I do see vulkan at ./ThirdParty/Vulkan/Linux/include/vulkan.

Nm solved.

Setting up VULKAN_SDK to point to ThirdParty/Vulkan/Linux/

Hey I’m on this problem right now. Where exactly can I find the VULKAN_SDK? This is my first time building UE4 so I’m very unfamiliar with all these dependencies.

Thanks.

ah nvm lol.

Didn’t realise you mean’t to simply change the #include.

Cheers
