I can't build a project for Ubuntu Arm64

For compatibility with older versions of CMake, option is clearing the normal variable 'NVRHI_INSTALL'. This warning is for project developers. Use -Wno-dev to suppress it.

You will need to download and install DXC. See the README Compiling on Linux Step 1.

https://github.com/RobertBeckebans/RBDOOM-3-BFG#compiling-on-linux-

Given you are running on Arm64, you may need to build DXC yourself - I'm not sure if there is a pre-built binary for Linux/Arm64.

There is one other option if available: check your distro for availability of package "directx-shader-compiler" or "DirectXShaderCompiler". If present you can install it the same as any other package and it will satisfy the dependency for building RBDoom3BFG.

@SRSaunders Please tell me, can I roll back the commits and build a project without shaders from Microsoft?

[SRSaunders]

Yes, you can use https://github.com/RobertBeckebans/RBDOOM-3-BFG/releases/tag/v1.4.0 instead. This older version is based on OpenGL (with some Vulkan support).

However, if you want to use the current master, you can try building DXC yourself using:

> git clone https://github.com/microsoft/DirectXShaderCompiler.git
> cd DirectXShaderCompiler/
> git submodule init; git submodule update
> mkdir build; cd build
> cmake .. -GNinja -DCMAKE_BUILD_TYPE=Release -C ../cmake/caches/PredefinedParams.cmake
> ninja
> cd bin
> ./dxc --version

Then put the dxc binary in your path and build RBDoom3BFG with Robert's instructions. It should work on Linux/Arm64 since it compiles and runs successfully on Apple Silicon (also arm64).

Thank you, thanks to you I was able to move forward. Unfortunately, I encountered the following errors during assembly: BUILDRB.log

RBDOOM-3-BFG v1.4.0 assembled successfully

dxc failed : error code 0x80004005.

I think this is a general file access error. Do you have recursive read permission at .../RBDOOM-3-BFG/neo/shaders as well as recursive write permission at .../RBDOOM-3-BFG/base/renderprogs2/spirv ?
