I was getting lots of these errors,
glsl-to-spirv-0.1.7/glslang/hlsl/../glslang/MachineIndependent/../Public/../Include/../Include/Common.h:99:
.../registry/src/github.com-1ecc6299db9ec823/glsl-to-spirv-0.1.7/glslang/hlsl/../glslang/MachineIndependent/../Public/../Include/PoolAlloc.h:314:54: error: 'operator=' is a private member of 'glslang::TPoolAllocator'
void setAllocator(TPoolAllocator* a) { allocator = *a; }
~~~~~~~~~ ^ ~~

TPoolAllocator& operator=(const TPoolAllocator&); // don't allow assignment operator

And had to replace the apparently now deprecated glsl-to-spirv with shaderc-rs in order to
see the tutorial and thought would be useful for others also.
