Я работал над учебником LLVM Kaleidoscope для OCaml. На third part of the tutorial, я переходите к примеру кода в папкеUnbound module llvm
OCaml-Kaleidoscope\Chapter3
Я встречая проблема при компиляции с
ocamlbuild toy.byte
на Cygwin. Это код, указанный в учебнике для компиляции.
Ошибка я получаю
''ocamlc.opt -c -o codegen.cmo codegen.ml
File "codegen.ml", line 5, characters 5-9:
Error: Unbound module Llvm
Exit code 2 while executing this command:
''ocamlc.opt -c -o codegen.cmo codegen.ml
Я посмотрел некоторые решения этой проблемы. Одно решение, которое я нашел в том, чтобы использовать
ocamlbuild -use-ocamlfind toy.byte -package llvm
вместо
ocamlbuild toy.byte
Однако, когда я пытался, что я получил эту ошибку:
Failure: ocamlfind not found on path, but -no-ocamlfind not used.
Чтобы исправить это я пытался:
opam install ocamlfind
Но ocamlfind является alr установленный.
Другое решение, которое я нашел было использовать:
opam install llvm
В результате:
The following actions will be performed:
- install llvm 3.7

Я использую версию 3.8.0 из LLVM и версии 4.02.3 от OCaml из this link.
Есть ли я на правильном пути? Что мне нужно сделать, чтобы исправить это?
