Llvm_bitreader.Error while running tutorial01.byte

I followed your tutorial and installed all packages you mentioned except clang. The last one I have installed with llgo things like in this readme. Thus, I have clang 5.0.0.

So, this clang produced me hello.bc file and when I do
LD_LIBRARY_PATH=/usr/lib/ocaml/llvm-3.5/ ./build/tutorial01/src/tutorial01.byte ./hello.bc

I get error:
Fatal error: exception Llvm_bitreader.Error("Invalid type for value")

Thanks in advance,

Cannot compile tutorial01.ml

I follow your first tutorial but got this message when I ran make

• ocaml version: 4.02.1

  It seems to be for an older version of OCaml.
  Command exited with code 2.
  Hint: Recursive traversal of subdirectories was not enabled for this build,
  as the working directory does not look like an ocamlbuild project (no
  '_tags' or 'myocamlbuild.ml' file). If you have modules in subdirectories,
  you should add the option "-r" or create an empty '_tags' file.

  To enable recursive traversal for some subdirectories only, you can use the
  following '_tags' file:

  true: -traverse
  <dir1> or <dir2>: traverse
