Using shared object (.so) by command opt in llvm

I am a llvm beginner. I run the command:

../llvm-6.0.0.src/build/bin/opt -load=./test.so -Hello < main.bc

according to the tutorial but got the error:

opt: CommandLine Error: Option 'use-dbg-addr' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options

I googled again and again, and got nothing about this error.

You need a LLVM build with shared libraries enabled, which corresponds to cmake options BUILD_SHARED_LIBS=On. You can check what type of LLVM you have installed by either checking its lib directory or executing:

llvm-config --shared-mode

This should report shared; anything else will require you to recompile.
