dxc fails to run with error code 0x80004002 on linux

[udnaan]

What

dxc fails with the following error

dxc failed : error code 0x80004002.

Where

Debian 10.5 X86_64

Why

The debugging leads to line 111 in dxcapi.use.h:
HRESULT hr = m_createFn(clsid, riid, (LPVOID*)pResult);

Which fails and throws an unknown exception.

Workaround

Investigation lead to it being caused due to LD_LIBRARY_PATH containing $VULKAN_SDK/lib directory. Still not sure why that would be or should be, still, taking out the $VULKAN_SDK/lib path fixes it.

Leaving it here in case someone else on linux runs into it.

Thanks for reporting @udnaan

This might have been a GCC-compiled libdxcompiler.so included in the Vulkan SDK? Either way that's solved now and IIDs are compared properly regardless of the compiler since #3062. I think/hope this is fixed and can be closed now from the DXC side 🙂.

Closing with the belief this is fixed. Please reopen or refile if it is not
