NI-DAQmx C在Node.js上的库

Question

I'm making a nodejs app that have to pull data from a NI USB 6210. National Instruments, gives away a bunch of examples that use their (pure) C libs, since, I'm on nodejs, I thought I could "easily" recycle them into a node module using node-gyp, but I discovered that node modules are more likely to be written in C++, rather than plain C ( as described in the reference ), so I was wondering about other possible solutions. Aside from that the whole library thing is also based on a bunch of frameworks ( on OSX )

    /Library/Frameworks/nidaqmxbase.framework
    /Library/Frameworks/nidaqmxbaselv.framework
    /Library/Frameworks/lib67xx.framework
    /Library/Frameworks/libDIO96.framework
    /Library/Frameworks/libESeries.framework
    /Library/Frameworks/libmiteDma.framework
    /Library/Frameworks/libMSeries.framework
    /Library/Frameworks/libSSeries.framework
    /Library/Frameworks/libUSB-92xx.framework

so my second question is how does the frameworks interact with nodejs? I've a little bit of confusion about this.

UPDATE

Thanks to @mscdex I've built my first node module that should just wrap the frameworks and make'em available on the node side. This is what I've done so far:

binding.gyp

{
    "targets": [
        {
            "target_name": "addon",
            "sources": [

            ],
            "include_dirs": [
                "./includes/NIDAQmxBase.h"
            ],
            "conditions": [
                [
                    "OS=='mac'",
                    {
                        "defines": [
                            "__MACOSX_CORE__"
                        ],
                        "architecture": "i386",
                        "link_settings": {
                            "libraries": [
                                "-framework",   
                                "nidaqmxbase",
                                "-framework",
                                "nidaqmxbaselv"
                            ]
                        }
                    }
                ]
            ]
        }
    ]
}

with this I've run the configure and the build commands

to be noticed that I'm using nw-gyp that is a hack of the node-gyp, because I need to build a module for node-webkit, but it's just like node-gyp with a few improvements.

This operation produced a file called addon.node (weighted 8kb)

After that I've tried to run a simple js test file

var ni = require('./libs/addon');

console.log(ni);

as I ran this it produced

Error: Symbol addon_module not found.
    at Module.load (module.js:352:32)
    at Function.Module._load (module.js:308:12)
    at Module.require (module.js:360:17)
    at require (module.js:376:17)
    at window.require (eval at undefined, <anonymous>:1:112)
    at eval (file:///Users/myUser/MyPath/MyNodeWebkitProject/public/js/ni-daqmx.js:1:10)

and that is where I'm stuck.

Answer 1

You can use/wrap C libraries in node (C++) with no problem.

As far as the frameworks go, you should be able to add those files as libraries in your binding.gyp file and gyp should automatically convert them to -framework lib67xx -framework libDIO96 ... linker flags.
