building rust

Hello

Anyone had success building rust? Even with LLVM 12, I still hit this error:
  cargo:warning=llvm-wrapper/PassWrapper.cpp: In function 'void LLVMRustPrintTargetCPUs(LLVMTargetMachineRef)':
  cargo:warning=llvm-wrapper/PassWrapper.cpp:397:57: error: 'const class llvm::M
CSubtargetInfo' has no member named 'getCPUTable'; did you mean 'getCPU'?
  cargo:warning=   const ArrayRef<SubtargetSubTypeKV> CPUTable = MCInfo->getCPUT
able();
