New to CMake, could use some help building hello_xr

phildo · August 5, 2020, 1:31am

I’ve cloned the whole https://github.com/KhronosGroup/OpenXR-SDK-Source repository to my desktop, and have run cmake (using “Visual Studio 16 2019”) generating the OPENXR.sln. Opening that solution, I right click on it and hit “build”. There were a whole lot of successes, and a couple failures. Mostly linker errors that appear to be referring to D3D.

So, is there some step I should be doing to explicitly link D3D? Or was cmake supposed to take care of that? What else do I need to do?

Hmm, it should work with no trouble - when did you clone it? There were some CMake bugs in 1.0.9, but 1.0.10 was recently released which included fixes for them. You’ll need to clear your build directory. I think that’s the problem here - CMake picked up the 32-bit libraries when building the 64-bit project.

In addition, I’d recommend building as RelWithDebInfo, rather than full Debug.

Make sure (in the Visual Studio Installer) that you are fully up to date and have the Windows Kits fully installed for all the platforms you want to build for.

looks like you don’t have d3dx lib on your computer.

install D3DX SDK should work.

I don’t think you want to install D3DX. That’s outdated and definitely not needed - I did not need to install it for CI to build. The actual answer was buried in my post - this is a “mix of architectures” problem.
