Instead of adding a new error category for your purpose, I think it would be better to just use make_dynamic_error_code(). It's simpler to use.

This doesn't seems a correct way to use Twine. This should be

  (Twine(errorStr) + "in file " ...).str()

instead of

  Twine(errorStr + "in file " ...).str()
