Hmm, it looks like an issue with shaderc - could it be that the locally available version of shaderc might be out-of-date?

Which flavour of Linux (and version) are you working with? In case it's Arch Linux, it might be that the shaderc package is installed separately, and needs updating.

Oh nice, Gentoo! :)

the only thing that looks a bit strange is the output of shaderc ... on my system i don't have a separate shaderc executable, and shaderc is a tool that was originally developed by google and then became part of the Vulkan SDK, while bgfx is its own engine...

I see from the bgfx docs that it provides a tool called shaderc, and that, when globally installed on your system, might perhaps be clashing with the Vulkan shaderc library of the same name...

change shaderc_combined to shaderc_shared in modules/le_shader_compiler/CMakeLists.txt fix this on fedora

[tgfrerer]

@simsilver that could be a workaround if a system does not provide shaderc_combined ...

Note that an Island application that was compiled against shaderc_shared will need to be bundled with libshaderc_shared.so in case it is not provided on the target system. Ideally, static Release builds are as self-contained as possible.

[simsilver]

Hmm, I have installed the shaderc_combined static lib, tried that if link with shaderc_combined, I need append "SPIRV MachineIndependent GenericCodeGen OGLCompiler OSDependent SPIRV-Tools SPIRV-Tools-opt" after shaderc_combined too on fedora, and the first 5 static lib from glslang-devel, last 2 shared lib from spirv-tools-libs

[tgfrerer]

@simsilver huh, looks like the shaderc_combined library is somehow different to what i have on ubuntu - or windows, for that matter... ideally, it shouldn't have to be this cumbersome to set it up. Could it be that your install is using a Fedora rpm package for shaderc, and not the version of shaderc that is provided with the Vulkan SDK tarball?

It's good to find out about these subtle differences between linux flavours, and installs... I think the default option should be to somehow find the local Vulkan SDK install, and use shaderc from there. I'm all ears for ideas of how this could be achieved more reliably :)
