Hi all, I'm using the boost logging library from the sandbox, in conjunction with boost 1.35.0. I'm seeing problems building basic sample code under Windows VS2005 in projects where UNICODE and _UNICODE is defined. Here's an example line of problematic code: g_log_err()->writer().add_formatter( formatter::idx(), "[%] " ); Here's the error generated: --snip-- 1>c:\sources\logutils.cpp(56) : error C2664: 'void boost ::logging ::writer ::format_write < formatter_base ,destination_base ,lock_resource ,apply_format_and_write ,router_type ,formatter_array ,destination_array

According to the documentation, the library should automatically sense the UNICODE definition under Windows and do the right thing. But that doesn't seem to work right. I played around with trying to get this to work, but found that I had to always pass non-wide strings to the various interfaces. Ultimately I gave up and disabled the logging of wide character strings by defining the following: #define BOOST_LOG_DONOT_USE_WCHAR_T For my particular needs, logging 8 bit characters probably makes more sense anyway. But it's somewhat bothersome that the logging library did not work out of the box as documented. Sorry in advance if I missed some other configuration or nuance needed to get the logging library to work under UNICODE. Best, -- Allen Cronce
