translation from cuda file to spv file

I realize the conversion from cuda file to spv file.
I first use LLVM to generate the .bc file corresponding to cuda file, and then use llvm-spirv to convert the .bc file into the .spv file.
get an error:

InvalidTargetTriple: Expects spir-unknown-unknown or spir64-unknown-unknown. Actual target triple is x86_64-pc-linux-gnu

how to solve it?

Start by checking how LLVM generates the .bc file and which target triple it uses before passing it to llvm-spirv. Compare that triple with the accepted spir-unknown-unknown or spir64-unknown-unknown targets; done means the CUDA-derived bitcode can be converted to .spv without the InvalidTargetTriple error.
