I want to test the autoscheduler "Li2018" on Ubuntu16.04. I exploit dlopen to load the libgradient_autoscheduler.so to my pipeline (the plugin of autoscheduler Li2018) and build it, but when I ran the executable file, an error has occured: 

CommandLine Error: Option 'ppc-use-base-pointer' registered more thanonce! LLVM ERROR: inconsistency in registered CommandLine options

I cannot understand what is the ppc-use-base-pointer and I don't think I have registered more than once. does someone is familiar with llvm? Or does someone met the same problem and have solved the problem? By the way, my llvm-config is 3.8.0.

  • I don't know LLVM but I think you need to show the commands you use to run LLVM so people know what you are talking about. – sba Dec 25 '19 at 23:26

If you look at the README (https://github.com/halide/Halide/blob/master/README.md), you need llvm with version >= 8.0 for Halide to properly run.
