Library not linking with Contract

Question

I am trying to do a small example contract of

Error deploying required libraries: Invalid bytecode format.

Here is the contract code

library CounterLib {
struct Counter { 
    uint i;


}

 function incremented(Counter storage self) returns (uint) {
    return ++self.i;
 }
}

contract CounterContract {
   using CounterLib for CounterLib.Counter;

   CounterLib.Counter counter;

   function increment() returns (uint) {
     return counter.incremented();
   }
}

How are you deploying this? With Truffle or Remix or something else?

If I copy this into Remix and deploy it with the Javascript VM it seems to work as expected, so there's nothing wrong with the code you've pasted above. Note that before deploying CounterContract it must be linked to the deployed CounterLib library. Linking takes the address of the deployed CounterLib library and copies it into the bytecode of the CounterContract before deployment.

Remix does linking automatically and Truffle requires you to specify linked contracts in the deploy script. What are you using and how are you linking the CounterLib with the CounterContract?

The issue is with my browser I think, I tried in another browser, the code works as expected and I also tried using private window, then also it worked fine. But I try to create using my normal browser window. I am getting this error. Don't know the reason, but for now using another browser.
