ocamlbuild;建筑toplevel

问题描述

成功，并使用ocamlfind，我发现难以构建顶层。

我构建了一个 .mltop 文件所有包含的模块，并将包添加到 _tags ，但是构建不工作。它找不到使用其中一个模块编译的C函数。使用 -classic-display ，我可以看到该文件 libcs​​ide.a ，不包括在内，不是甚至编译了！ c文件作为依赖关系添加到 myocamlbuild.ml 中，

  flag [link; ocaml; use_cutil]（S [A-cclib; A-L。;]）; 
 dep [link; ocaml; use_cutil] [libcs​​ide.a]; 
  

和 _tags ，

 < utilities。*> ：use_cutil 
< ** / *。top> ：use_str，use_unix，use_cutil，use_curl，use_mysql 
  

，最后在 libcs​​ide.clib ，

  cutil.o 
  

我在设置顶级构建时缺少一些东西，但是我找不到可靠的在线资源。

解决方案

• 我假设cutil.ml描述了ocaml侧的libcs​​ide.a -


• 使用当前插件cutil ocaml库不会链接libcs​​ide.a（



这里有一个简单的（和工作的）方法来构建项目本地ocaml库C存根。在myocamlbuild.ml中：

  ocaml_liblinuxnet 
 let liblinuxnet_stubs =liblinuxnet_stubs。 ^！Options.ext_lib in 
 flag [link; ocaml; use_linuxnet]（S [A-cclib; A liblinuxnet_stubs;]）; 
 dep [link; ocaml; use_linuxnet] [liblinuxnet_stubs]; 
  

在liblinuxnet_stubs.clib中：



<$ p $请注意，C源代码被称为<$ c linuxnet_c.o



$ c> linuxnet_c.c ，以便生成的目标文件不会覆盖从linuxnet.ml（或反之亦然）的文件。最后在_tags中：

  true：use_linuxnet 
  

使用这个设置，它可以在toplevel（注意，没有必要把 Linuxnet 放入.mltop原因linuxnet.cma将被添加到链接 use_linuxnet 标志（使用 ocaml_lib 使用））

Having successfully reorganized my project for ocamlbuild with subdirectories and using ocamlfind, I've found it difficult to build the top-level.

I've constructed a .mltop file containing all the modules that would be included and added the packages to the _tags, but the build doesn't work. It cannot find the C functions that are compiled with one of the modules. With -classic-display on, I can see that file, libcside.a, not being included and isn't even being compiled at all! The c file is added as a dependency in myocamlbuild.ml by,

flag ["link"; "ocaml"; "use_cutil"] (S [A"-cclib"; A"-L."; ]);
dep  ["link"; "ocaml"; "use_cutil"] ["libcside.a"];

and in _tags,

<utilities.*> : use_cutil
<**/*.top> : use_str, use_unix, use_cutil, use_curl, use_mysql

and, finally, in libcside.clib,

cutil.o

I'm missing something in setting up the build for the top level, but I cannot find a reliable resource online. Thanks.

解决方案

• I presume that cutil.ml describes ocaml side of libcside.a - correct?
• Did you put Cutil in mltop?
• With your current plugin cutil ocaml library will not link libcside.a in (dep only instructs ocamlbuild to build it, not link)

• Here is a simple (and working) way to build project-local ocaml library with C stubs. In myocamlbuild.ml:

  ocaml_lib "linuxnet";
  let liblinuxnet_stubs = "liblinuxnet_stubs." ^ !Options.ext_lib in
  flag ["link"; "ocaml"; "use_linuxnet"] (S[A"-cclib"; A liblinuxnet_stubs;]);
  dep  ["link"; "ocaml"; "use_linuxnet"] [liblinuxnet_stubs];
  

  In liblinuxnet_stubs.clib:

  linuxnet_c.o
  

  Notice that the C source is called linuxnet_c.c so that the resulting object file doesn't override the one from linuxnet.ml (or vice versa). And finally in _tags:

  true: use_linuxnet
  

  With this setup it will be available in toplevel (note that there is no need to put Linuxnet into .mltop cause linuxnet.cma will be added to link by use_linuxnet flag (generated with ocaml_lib usage)).
