如何在binding.jp扩展的binding.gyp node-gyp中为静态库添加依赖性

Question

我有一个简单的binding.gyp文件,用于构建我的node.js扩展.我想更改库"mylib"的链接方法并静态链接它而不是使用共享库.

{
  "targets": [
    {
      "target_name": "myext",
      "sources": [
        "code/main.cpp",
        "code/load.cpp",
        "include/load.h"
      ],
      "include_dirs": [
        "include", "../Library/include"
      ],
      "libraries": [
        "-lmylib", "-L/home/admin/MyLib/Library/binaries/linux/Release"
      ],
      "cflags!": [ "-fno-exceptions" ],
      "cflags": [ "-std=c++11" ],
      "cflags_cc!": [ "-fno-exceptions" ]
    }
  ]
}

mylib的静态和共享版本位于同一目录中:

# ls /home/admin/MyLib/Library/binaries/linux/Release
libmylib.a libmylib.so

我想静态链接以避免库安装/加载问题.

Answer 1

只需在"libraries"部分添加静态.a或.so文件的路径,

"libraries":["/ usr/local/lib/libnetfilter_queue.so.1.3.0"]

Answer 2

您可以让node-gyp使用内置变量为您插入路径module_root_dir 如果我正确解释您的代码,请将您更改libraries为例如:

"libraries": [
    "-lmylib",
    "-L<(module_root_dir)/../Library/binaries/linux/Release"
],

可能会做的伎俩.虽然我不确定它是否会与版本.a或.so版本链接,但指定您可以尝试:

"libraries": [
    "<(module_root_dir)/../Library/binaries/linux/Release/libmylib.a"
],

同出的-L前缀和-lmylib.此外,我有点不确定你是否被允许遍历根目录.我之前没有测试过使用模块根目录之上的任何内容.除此之外你应该好好去.
