我有一个本地固定的OPAM项目,名为ojasmine,我希望将其编译为库,供另一个名为test_tournabox的项目使用(最终编译成JavaScript)。然而,test_tournabox的编译失败了,出现了链接错误。
我按照以下方式编译ojasmine,生成目标文件ojasmine.cma:
我发现奇怪的是ojasmine.cma不在我的项目目录中,而是在_build目录中。
输出结果为:
这会导致以下错误:
似乎ojasmine.cma没有链接到可执行文件test_tournabox.byte中,但我希望ocamlfind的-linkpkg参数能够安排这个问题。我错过了什么?
编辑:以下是META文件:
我按照以下方式编译ojasmine,生成目标文件ojasmine.cma:
ocamlbuild -cflag -annot -use-ocamlfind -pkgs js_of_ocaml.log,js_of_ocaml,js_of_ocaml.syntax -syntax camlp4o ojasmine.cma
Finished, 5 targets (5 cached) in 00:00:00.
接下来我这样安装:
ocamlfind install ojasmine META _build/ojasmine.cma
我发现奇怪的是ojasmine.cma不在我的项目目录中,而是在_build目录中。
输出结果为:
Installed /home/laheadle/.opam/4.02.0/lib/ojasmine/ojasmine.cma
Installed /home/laheadle/.opam/4.02.0/lib/ojasmine/META
接下来,我使用cd
命令进入我的tournabox项目并尝试构建测试套件:
ocamlbuild -cflag -annot -use-ocamlfind -pkgs js_of_ocaml.log,js_of_ocaml,js_of_ocaml.syntax,ojasmine -syntax camlp4o test_tournabox.byte
+ ocamlfind ocamlc -linkpkg -syntax camlp4o -package ojasmine -package js_of_ocaml.syntax -package js_of_ocaml -package js_of_ocaml.log choice.cmo util.cmo entry.cmo ttypes.cmo columns.cmo countries.cmo country_group.cmo jsutil.cmo performance_group.cmo round_group.cmo seed_group.cmo tlog.cmo tourney.cmo tournabox_lib.cmo test_tournabox.cmo -o test_tournabox.byte
这会导致以下错误:
Error: Error while linking test_tournabox.cmo:
Reference to undefined global `Ojasmine'
似乎ojasmine.cma没有链接到可执行文件test_tournabox.byte中,但我希望ocamlfind的-linkpkg参数能够安排这个问题。我错过了什么?
编辑:以下是META文件:

ocamlfind 看到了它:
(trusty)laheadle@localhost:~/ocaml/ojasmine$ ocamlfind query ojasmine

这里是:
(trusty)laheadle@localhost:~/ocaml/ojasmine$ ls `ocamlfind query ojasmine`
META ojasmine.cma
这里是ojasmine.ml:
open Js
let describe (s : js_string t) (f: unit -> unit) : unit =
Js.Unsafe.fun_call (Js.Unsafe.variable "describe")
[| Js.Unsafe.inject s;
Js.Unsafe.inject (Js.wrap_callback f) |]
let it (s : js_string t) (f: unit -> unit) : unit =
Js.Unsafe.fun_call (Js.Unsafe.variable "it")
[| Js.Unsafe.inject s;
Js.Unsafe.inject (Js.wrap_callback f) |]
class type matcher = object
method toBe: bool t -> unit meth
method _not: matcher t readonly_prop
end
let expect_bool (b: bool t) : matcher t =
Js.Unsafe.fun_call (Js.Unsafe.variable "expect") [|Js.Unsafe.inject b; |]
同时还有 ojasmine.mli:
open Js
val describe: js_string t -> (unit -> unit) -> unit
val it: js_string t -> (unit -> unit) -> unit
class type matcher = object
method toBe: bool t -> unit meth
method _not: matcher t readonly_prop
end
val expect_bool: bool t -> matcher t
ojasmine.cma
运行ocamlobjinfo
的输出吗? - ivg
