[C++-sig] Compile error when using exception_translation.hpp

[Ger van Diepen]

When compiling the following code using gcc-4.3.2 and boost-1.37, I get
errors as listed at the end. It also fails for boost-1.40 and gcc-4.3.4.

It is solved when patching translate_exception.hpp by adding
# include <boost/type_traits/add_reference.hpp>

Is it a Boost-Python problem or do I do something wrong?
Of course, I can include that file in my own code, but that does not
seem the correct solution to me.

Thanks,
Ger van Diepen


  #include <boost/translate_exception.hpp>
  #include <stdexcept>
  void translate_stdexcp (const std::exception& e)
  {
    PyErr_SetString(PyExc_RuntimeError, e.what());
  }

  //# Note that the most general exception must be registered first.
  void register_convert_excp()
  {
    boost::python::register_exception_translator<std::exception>
      (&translate_stdexcp);
  }
