SocialLib aims to make the development of Social apps much more easier. Currently, Social Lib provides access to the following social networks :

• Facebook
• Twitter
• Google
• Buzz
• LinkedIn

Now My scenario:

I created apps in Twitter, facebook and generated API and secret keys.

I tried to follow the guide in the wiki page of SocialLibs.

But unfortunately i'm stuck.. I need someone to point to a working source of connection and posting to facebook, twitter...etc

Here is the code that i tried out.. can someone correct me if there is some errors..?

Answer 1

It seems that is missing an oauth library. Is it possible that you need to include oauth-signpost?
