Are these compiler errors or IDE errors?

C++ IDEs sometimes give false positive errors about C++ code due to
incorrect configuration or bugs in the IDE's C++ parser. These issues
are IDE-specific, so you are unlikely to be able to find help with
them on boost-users (try your IDE vendor's mailing list/support channels
instead). At the same time, such errors don't prevent you from
actually compiling and running your code.

If you are getting actual compiler errors, we can help you with those
if you post:
  1. What compiler and version you are using ("Sourcery CodeBench"
     isn't it, that's an IDE that will use some compiler like GCC 
     for actual compilation).
  2. A short (but complete) code example that fails to compile.
  3. The compiler errors that you are getting.
