Compile using LLVM obfuscator to add parameters with the following error:

clang (LLVM option parsing): for the -bcf option: may only occur zero or one times!

Copy all the compilation parameters, carefully compare and find that there are duplicates

-DINIT_SCRIPTING_BACKEND=1

-mllvm

-bcf

-fno-strict-overflow

-DINIT_SCRIPTING_BACKEND=1

-mllvm

-bcf

So look at the CFlag configuration of Xcode and find that there is a $(inherited) parameter. Delete this parameter.
