Question: No Object File generated

[Jaliborc]

Fresh Falcor install. Using Microsoft Visual Studio on Windows 10. All build modes result in the error:

warning treated as error - no object file generated (compiling source file Utils/Platform/Windows/Windows.cpp)

Anyone knows what might cause this?

[nbentyNV]

Can you post the entire log? There should be a warning message before the error

[Jaliborc]

Here is the full log. The result is the same with other build modes (DebugVK, DebugD3D12, etc).

Try updating your compiler. I think we require Visual Studio 2017 version 15.9.x (Help->About will show you the version, and Help->Check for updates will update it)

[Jaliborc]

Tried updating just to double-check, but I am running the current latest version 16.2.1. Is that not compatible?

[nbentyNV]

Oh, you're on VS 2019. We never tried using 2019, so I don't know if something changed there in a way that is incompatible with our project files.

I suggest you stick to VS 2017 as this is the version we are using internally.

[Jaliborc]

Will try that then

[Jaliborc]

That worked. Thank you for the help.
