node c/c++扩展模块build失败.

"深入浅出nodejs 朴灵" 例子 c/c++扩展模块

http://diveintonode.org/

在作者的帮助下,build成功. 下面贴出的hello.cc和binding.gyp都是已经过时的代码了(暂时保留).

应该以官方最新例子(https://nodejs.org/docs/latest/api/addons.html)为准.

hello.cc

#include <node.h>
#include <v8.h>

using namespace v8;

Handle<Value> SayHello(const Arguments& args){
	HandleScope scope;
	return scope.Close(String::New("Hello world!"));
}

void Init_Hello(Handle<Object> target){
	target->Set(String::NewSymbol("sayHello"), FunctionTemplate::New(SayHello)->GetFunction());
}

NODE_MODULE(hello, Init_Hello)

binding.gyp

{
	'targets':[
		{
			'target_name':'hello',
			'sources':[
				'./hello.cc'
			],
			'conditions':[
				['OS == "win"',
				{
					'libraries':['-lnode.lib']
				}
				]
			]
		}
	]
}

configure没有问题:

在网上搜索了下:  http://www.imooc.com/qadetail/38800 , http://stackoverflow.com/questions/32964144/gyp-err-stack-error-c-program-files-x86-msbuild-12-0-bin-msbuild-exe-fail ,

最靠谱的应该还是 https://www.npmjs.com/package/node-gyp

Windows 7/8:
Microsoft Visual Studio C++ 2013 for Windows Desktop (Express version works well)

但是,我还没装"Microsoft Visual Studio C++ 2013", studio文件太大,下载要很久. 我在网上找的一个"Microsoft Visual C++ 2013运行库",安装了,没效果. 这个等以后下载了studio再验证下.

==============================================================================

在安装了MS studio 2013之后,仍然报错.记录如下:

build 仍然失败. 看提示貌似是hello.cc文件编写错误.目前没能力搞定.先放放.

==============================================================

在作者的帮助下,build成功.

C++的接口一直在变化，参考：https://nodejs.org/docs/latest/api/addons.html

按照官方给的例子,修改hello.cc和binding.gyp,再依次执行node-gyp configure , node-gyp build 就可以了.
