I have a sol file with a library and also a contract.

The contract can use the library and everythings deploys correct using the solidity-browser.

If I add a new library and call a function of that new library then I get the following browser-solidity error during deployment -

    Error deploying required libraries: Invalid bytecode format.

Does solidity support a contract using multiple libraries? If it does do I then need to do something else to enable using multiple libraries in a contract?

Solidity code example -

library MyLibrary_1
{
    function MyLibrary_1()
    {

    }

    function TestFunction() public
    {
        uint8 value = 5 + 5;
    }
}

library MyLibrary_2
{
    function MyLibrary_2()
    {

    }

    function TestFunction() public
    {
        uint8 value = 5 + 5;
    }
}

contract MyContract
{
    function MyContract()
    {

    }

    function MyContract_function() public
    {
        MyLibrary_1.TestFunction();
        MyLibrary_2.TestFunction();
    }

    function() 
    {
        throw;
    }
}   
  • Can you provide minimal source to reproduce this, or export your browser-solidity workstation to a gist? I don't believe there is enough information here to answer your question. – Piper Merriam Aug 12 '16 at 16:22
  • Added a solidity code example for the issue. – Alex Darby Aug 12 '16 at 16:43

Found the issue. Do not use underscore characters when naming a solidity library as the solidity linker cannot process this character correctly during deployment.
