@Sergiy-Kyrylkov update your Firmware with oupgrade and update opkg with opkg update and then install nodejs with
opkg install nodejs.

@Boken-Lin I've placed it in a hello folder within node_modules but if i require it like you said i get a Module/File not found, i also placed a package.json in there but it wont work

@Boken-Lin Nope i copied the entire folder containing the compiled hello world example and launched a repl in the folder that i posted above.

@Boken-Lin I have compiled my module for MIPS Arch but now i get a "File not found" Error from node if i want to require it.

> var hello = require('./hello')

@Boken-Lin How Do I do this?

@Boken-Lin: Sure, i'd love to!
First my Specs:

Asus Zenbook (ux32a)
Ubuntu 15.10 64bit (just a fresh install for the cross compiling, build-essential, gcc & etc preinstalled)

Well i thought i can make a wrapper for "fast-gpio" using Windows 7 64bit but then i saw that it requires unix only headers.
Hmmm, ok, just for this i have made a clean install of ubuntu 15.10 on my laptop, installed node and npm and installed node-gyp.
I ported most of the code on my Windows PC and copied all to my laptop and compiled it with node-gyp.
Here my gyp file:

{
    'targets': [
        {
        'target_name': 'gpio',
        'sources': [ 'src/gpio.cpp' ],
        'include_dirs': [ 'inc' ]
        }
}

And a screen of the error:

Here is also the readelf log:

> readelf -h gpio.node

Thats pretty much it.
Greetings from Germany!

Is there any way to cross compile node addons for MIPS because if i compile it with Ubuntu 15.10 it says that my addon dont has a correct ELF Header.
Im pretty much done porting the fast-gpio lib to node.js but i have this error weile requiring it.
