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

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

}
