I am trying to get my hands dirty of firefox OS apps. I tried to follow instructions on https://developer.mozilla.org/en/docs/Gecko_SDK to get the SDK. I downloaded Gecko 22.0 (Firefox 22.0) zip file for windows. Could anyone please tell me how to build it on windows system. The details given on the website are not as clear as I expected(I had expected them to be like that on android's site). Or is there a binary available for the SDK?
No SDK needed, it is all HTML5. If people talk about SDKs in that context, its often frameworks or maybe tools that can export to HTML5. But generally, you can use all the languages that work in a browser and use them without any framework or SDK to make an app.
The developer docs on Marketplace have this great intro on app development and testing: https://marketplace.firefox.com/developers/docs/quick_start
Happy Hacking!
