libvulkan-1.dll missing but no fix-libvulkan-1.dll-missing-error.cmd #113

Closed grochoge closed 1 year ago

grochoge commented 1 year ago

I attempted to perform a per-app install for a 32-bit application that uses OpenGL with mesa3d-22.1.6-release-mingw.7z. In this case within Windows Sandbox for testing.

The application fails to launch due to vulkan-1.dll not being found.

The README says to run fix-libvulkan-1.dll-missing-error.cmd, but this file does not existing within the package.

Would it be best to just modify the readme to direct people to https://vulkan.lunarg.com/sdk/home to download the runtime directly? That did fix the issue for me.

I actually have this in readme, but you stopped at the wrong paragraph in known issues section. This is the right paragraph:

Mesa opengl32.dll from MinGW package depends on Vulkan runtime since 21.0.0. This is an upstream regression introduced when zink driver was patched to support Windows.

This issue was fixed in Mesa 22.2. You can try 22.2.0-rc2 if you want.

As for fix-libvulkan-1.dll-missing-error.cmd that's only needed when Mesa3D zink driver is built with MSYS2 MinGW-W64 vulkan-devel group instead of LunarG Vulkan SDK. I haven't been doing so for months, specifically since this patch landed in MSYS2. Now if you try to use a Mesa build with MSYS2 MinGW-W64 vulkan-devel group it crashes with unresolved symbols when trying to load LunarG Vulkan runtime.
