Failed writing shader header files

[jworch]

Hi, when trying to compile the samples, I get an error related to the shaders:

1>------ Build started: Project: pbr_uwp, Configuration: Debug ARM64 ------ 1>failed writing F:\work\OpenXR-MixedReality\obj\Debug\ARM64\pbr_uwp\CompiledShaders\PbrPixelShader.h 1>failed writing F:\work\OpenXR-MixedReality\obj\Debug\ARM64\pbr_uwp\CompiledShaders\PbrVertexShader.h 1>failed writing F:\work\OpenXR-MixedReality\obj\Debug\ARM64\pbr_uwp\CompiledShaders\HighlightPixelShader.h 1>PbrResources.cpp 1>F:\work\OpenXR-MixedReality\shared\pbr\PbrResources.cpp(9,10): fatal error C1083: Cannot open include file: 'PbrPixelShader.h': No such file or directory 1>C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\XamlCompiler\Microsoft.Windows.UI.Xaml.Common.targets(482,5): error MSB4181: The "CompileXaml" task returned false but did not log an error. 1>Done building project "pbr_uwp.vcxproj" -- FAILED. ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Any idea what's wrong? The BasicXrApp compiles and runs on Hololens 2 without any problem. Which additional information do you need to help?

I think this might be related to a recent Visual Studio update causing the shader compiler to no longer create any missing directories as needed. Until we get an update out to work around this, you can create the folder "F:\work\OpenXR-MixedReality\obj\Debug\ARM64\pbr_uwp\CompiledShaders" to work around it.

Yes, you were right. Thanks a lot!

@jworch FYI, Bryce made a fix for this issue and I merged the fix into latest master day. If you sync to latest, you shouldn't see above errors even without the workaround above. Please let us know if you still hit any issue.

@yl-msft Verified: The fix works for me. Just tried it. Thx a lot.
