Re: [Boost-users] boost.exception errors

I think the problem is that you're missing the aliasing support in shared_ptr which was added to the boost trunk at revision 37402 and is used by Boost Exception. -- Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode On Sat, Apr 12, 2008 at 11:25 AM, Olaf Peter wrote:

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, 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::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::shared_ptr(const boost::shared_ptr&)

from this file:

#include #include #include #include <exception> #include

#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 function = get_error_info( e ); // shared_ptr file = get_error_info( e ); // shared_ptr line = get_error_info( 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?
