Wrong library_path in lvp_icd.x86_64.json #1

Closed StefanG3D closed 3 months ago

Absolute path in mesa-lavapipe-*.zip would only work on the computer it had been built on _"library_path": "D:\a\build-mesa\build-mesa\mesa-llvmpipe\bin\vulkanlvp.dll"

It should be: _"library_path": ".\vulkanlvp.dll"

Almost there in the new archive, this forum ate a backslash. Windows insists on a dot and 2 backslashes "library_path": ".\\vulkan_lvp.dll"

Also i added a batch file in the same folder with following content: setx /m VK_ADD_DRIVER_FILES %~dp0\lvp_icd.x86_64.json

Hmm, I tried to run with set VK_ICD_FILENAMES=lvp_icd.x86_64.json (with just "library_path": "vulkan_lvp.dll" inside) and vkcube.exe was running using vulkan_lvp.dll file. The VK_ADD_DRIVER_FILES variable did not work for me regardless of json content - relative path or absolute path.

I'm not sure why my system is picky with the library_path

Looks like there is VK_ADD_DRIVER_FILES and VK_DRIVER_FILES which is equal to VK_ICD_FILENAMES according to https://vulkan.lunarg.com/doc/view/1.3.211.0/linux/LoaderDriverInterface.html#user-content-overriding-the-default-driver-discovery I think i have to check if misc. apps prefer a particular method...
