1.
Use node-gyp
npm install -g node-gyp
2.
Build with vc++ compiler
I.
First, install python 2.7.
II.
Install Visual studio 2015
community.
III.
In node.js promot type:npm config set python python2.7npm config set msvs_version 2015
Note: I couldn’t build successfully with
VC++ build tools 2015; the error was the version of compiler is wrong. I solved
this problem after install VS2005 community.
3.
New a file “binding.gyp” in
your working folder. The content is
{<pre class="prettyprint">
"targets": [
{
"target_name": "binding", ## the name you want
"sources": [ "src/binding.cc" ], ## the cpp source
code path
'include_dirs': ['include'],
'libraries': ['lib/lua53.lib' ]
}
]
}
</pre>
4.
Generate binding.cc which calls
lua C API
<code class="prettyprint">
#include <node.h>
#include "lua.hpp"
namespace demo {
using v8::FunctionCallbackInfo;
using v8::Isolate;
using v8::Local;
using v8::Object;
using v8::String;
using v8::Value;
lua_State *L ;
int
luaadd ( int x, int y )
{
int sum;
lua_getglobal(L, "add");
lua_pushnumber(L, x);
lua_pushnumber(L, y);
lua_call(L, 2, 1);
sum = (int)lua_tonumber(L, -1);
lua_pop(L, 1);
return sum;
}
void Method(const
FunctionCallbackInfo<Value>& args) {
Isolate* isolate = args.GetIsolate();
L =
luaL_newstate();
luaL_openlibs(L);
/*
Load the file containing the script we are going to run */
int
status = luaL_dofile(L, "add.lua");
if
(status) {
/*
If something went wrong, error message is at the top of the stack */
fprintf(stderr, "Couldn't load file: %s\n", lua_tostring(L,
-1));
exit(1);
}
int
sum = luaadd( 10, 11);
//String::NewFromUtf8(isolate, "C addon working:");
args.GetReturnValue().Set(sum);
lua_close(L);
}
void init(Local<Object> exports) {
NODE_SET_METHOD(exports, "hello", Method);
}
NODE_MODULE(addon, init)
}
</code>
</code>
Note: include lua.hpp when using C++
compiler.
5.
Create add.lua in the working
folder
function add(x,y)
return x+y
end
6.
Create hello.js in the woring
folder
// hello.js
const addon =
require('./build/Release/binding.node');##your target name in binding.gyp .node
console.log(addon.hello());Command: node-gyp
configure ## your export method name in cpp
7.
Place the lua.lib in the “/build”
folder in your working folder. Don’t have to place lua.exe or lua.dll.
8.
Command: node-gyp configure
9.
Command: node-gyp build
10. Node.js cmd: Node hello.js
You can see the result from lua
