如何编译使用JsooTop模块的文件?

问题描述 投票:0回答:1

我在一个名为main.ml的文件中有这个:

let () = JsooTop.initialize ()

我尝试使用以下方法编译文件:

ocamlfind ocamlc -package js_of_ocaml -linkpkg -o main.byte main.ml

但是出现此错误:

File "main.ml", line 1, characters 9-27:
Error: Unbound module JsooTop

似乎我的机器上没有JsooTop,所以我运行了opam install js_of_ocaml-toplevel,并尝试使用以下方法再次编译该文件:

ocamlfind ocamlc -package js_of_ocaml -package js_of_ocaml-toplevel -linkpkg -o main.byte main.ml
js_of_ocaml main.byte

但我收到警告:

来自ocamlfind的警告:

findlib: [WARNING] Interface topdirs.cmi occurs in several directories: /usr/lib/ocaml, /usr/lib/ocaml/compiler-libs

来自js_of_ocaml可执行文件的警告:

There are some missing primitives
Dummy implementations (raising 'Failure' exception) will be used if they are not available at runtime.
You can prevent the generation of dummy implementations with the commandline option '--disable genprim'
Missing primitives provided by +dynlink.js:
  caml_add_debug_info
  caml_dynlink_add_primitive
  caml_dynlink_get_current_libs
  caml_dynlink_lookup_symbol
  caml_dynlink_open_lib
  caml_remove_debug_info
Missing primitives provided by +toplevel.js:
  caml_get_current_environment
  caml_get_section_table
  caml_invoke_traced_function
  caml_realloc_global
  caml_reify_bytecode
  caml_static_alloc
  caml_static_free
  caml_static_release_bytecode
  caml_terminfo_setup

我的问题是:编译使用JsooTop模块的文件的正确方法是什么?

ocaml ocamlfind js-of-ocaml

首先,确保所需的OPAM包存在:

opam install js_of_ocaml js_of_ocaml-toplevel

要构建使用JsooTop模块的程序,请以这种方式编译文件:

ocamlfind ocamlc -package js_of_ocaml -package js_of_ocaml-toplevel -linkpkg -o main.byte main.ml
js_of_ocaml --toplevel --dynlink +dynlink.js +toplevel.js main.byte

请注意包含--toplevel--dynlink+dynlink.js+toplevel.js。上面的命令将生成一个名为main.js的JavaScript文件。
