code::ExtensionLoader Class Reference

Detailed Description

This class, used by Baseline will use the environment variable W2_EXTENSION_LIBS which is a colon-separated list of libraries e.g:.

     setenv W2_EXTENSION_LIBS hires:yourformat
     

The extension library should self-register. You can't use _init because it is currently broken on Linux due to crti.S exporting _init() as well. Here is one way to do it:

     namespace{
       struct HiresSelfRegister{
         HiresSelfRegister()
         {
call your factory functions here
            HiresIntroducer :: initialize();
         }
       };
       HiresSelfRegister myregisterer;
     }
