[Boost-users] boost.exception errors

Hi,

I've used the boost.exception from svn (Revision 44352) and got the 
compile errors:

$ LANG=en g++ -I ../../3rd_party/boost-svn/ -Wall eh.cpp -o eh && ./eh
../../3rd_party/boost-svn/boost/exception/info.hpp: In function 
'boost::shared_ptr<const typename ErrorInfo::value_type> 
boost::get_error_info(const E&) [with ErrorInfo = 
boost::error_info<boost::tag_throw_function, const char*>, E = 
boost::exception]':
eh.cpp:21:   instantiated from here
../../boost-svn/boost/exception/info.hpp:104: error: no matching 
function for call to 'boost::shared_ptr<const char* 
const>::shared_ptr(boost::shared_ptr<const 
boost::exception_detail::error_info_base>&, const char* const*)'
/usr/include/boost/shared_ptr.hpp:144: note: candidates are: 
boost::shared_ptr<T>::shared_ptr() [with T = const char* const]
/usr/include/boost/shared_ptr.hpp:131: note: 
boost::shared_ptr<const char* const>::shared_ptr(const 
boost::shared_ptr<const char* const>&)

from this file:

#include <boost/exception/exception.hpp>
#include <boost/exception/info_tuple.hpp>
#include <boost/exception/info.hpp>
#include <exception>
#include <boost/shared_ptr.hpp>

#include <iostream>

struct test_exception : boost::exception {};

int main()
{
     try {
         throw test_exception()
             << BOOST_ERROR_INFO
             ;
     }
     catch( const boost::exception& e ) {
         using namespace boost;
         std::cerr << "Caught exception:\n" << e.what() << "\n";
         shared_ptr<const char * const> function = 
get_error_info<throw_function>( e );
//         shared_ptr<const char * const> file = 
get_error_info<throw_file>( e );
//         shared_ptr<int* const>    line = get_error_info<throw_line>( e );
//         std::cerr << "  in " << file << "(" << line << "): " << 
function << std::endl;
     }
}

BTW, the example_io.cpp doesn't compile too. Do I have to use the 
complete svn trunk?

Thanks,
Olaf
