Subject: [Boost-users] [PostgreSQL+SOCI+BOOST] SOCI compile error in core\exchange-traits.h with PG and SOCI on Windows

Hi.



This isn’t strictly a Boost question but I’ve gotten no response to the following

issue posted on the SOCI-users list. I’m posting here in the hope that someone has

experience building SOCI for PostgreSQL with Boost type support on Windows.



Configuration:

Using SOCI 3.2.3, Boost 1.59.0, PostgreSQL 9.4 (same with 9.5b2),

and Microsoft Visual Studio 2010 on Win 7 Pro 64-bit (everything but OS is 32-bit).



Target is 32-bit SOCI DLL with PostgreSQL support and Boost integration (at least tuple).



Ran 'soci_postgresql_test.exe' and all tests under 'SOCI PostgreSQL Tests' passed except:

                test 6 skipped (dynamic backend)

                NOTICE: table "soci_test" does not exist, skipping

                NOTICE: table "soci_json_test" does not exist, skipping

                NOTICE: table "soci_test" does not exist, skipping



I can build an application that doesn't use boost::tuple without error.

However, if I do use boost∷tuple, I get:

  c:\develop\soci-3.2.3\core\exchange-traits.h(40): error C2065: 'x_type' : undeclared identifier

                int i;

                std::string s;

                sql << "SELECT i, s FROM t WHERE i = 0", soci::into(i), soci::into(s);

                std::cout << i << "\t" << s << std::endl;



                boost::tuple<int, std::string> r;

// following line causes error C2065: 'x_type' : undeclared identifier in core\exchange-traits.h

                sql << "SELECT i, s FROM t WHERE i = 0", soci::into(r);

                std::cout << r.get<0>() << "\t" << r.get<1>() << std::endl;



                return(0);
