Help Building for Fedora Linux

[adro79]

First of all, thanks for upgrading Aurora and its USD version.

I've been trying to build Aurora all day, but I keep having A LOT of errors. I even tried to build it on an Ubuntu 20.04 Container using Distrobox, but I encounter the same errors as my host machine.

Would appreciate some help since I'm not that advanced in programming :)

Here's a diff of the patches I made:

Minifying Shaders

It seems to be an issue in MainEntryPoints.slang, also it doesn't automatically set the Slang Compiler, so I have to specify it using Slang_COMPILER

[  4%] Minifying path tracing shaders to /home/adro/Applications/Aurora/SourceFedora/Build/Libraries/Aurora/CompiledShaders/CommonShaders.h
Compiling main entry point /home/adro/Applications/Aurora/SourceFedora/Libraries/Aurora/Source/Shaders/MainEntryPoints.slang with Slang compiler /home/adro/Applications/Aurora/Externals/Slang/bin/linux-x64/release/slangd to DXIL in header /home/adro/Applications/Aurora/SourceFedora/Build/Libraries/Aurora/CompiledShaders/MainEntryPoints.h

A workaround (?) is to manually execute the python command: python Scripts/minifyShadersFolder.py Libraries/Aurora/Source/Shaders Build/Libraries/Aurora/CompiledShaders/CommonShaders.h

Thanks a lot in advance.

We found that we have a merge error that prevents the Vulkan backend from working. Basically it is using old code, and we will update it to use the proper new code. Windows is fine, so please try that for now if you are able. We will issue a patch release to fix Vulkan / Linux. Thanks for your patience!
