Summary

implementations/Crafter.Graphics-GamepadWin32.c:49 compares interface IDs against IID_IUnknown and IID_IAgileObject, which MinGW defines in libuuid, and project.cpp's Win32 link flags (:73-81 at 852ae8a) don't include -luuid. Window::StartSync calls Gamepad::Tick, which pulls the gamepad code in, so a Win32 executable that runs the event loop does not link:

ld.lld: error: undefined symbol: IID_IUnknown
ld.lld: error: undefined symbol: IID_IAgileObject

Seen linking TextWin32 for x86_64-w64-mingw32. PointerWin32, and any example or application built for that target, needs it as well.

Suggested fix

cfg.linkFlags.push_back("-luuid"); beside -lruntimeobject. The two other things the Wine runs of those tests needed come from outside this project: an import library for vulkan-1, which the toolchain does not ship, and a definition of __libc_single_threaded, which the MinGW build of Crafter.Asset references (AGENTS.md, "Cross targets").
