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 formatter_base = boost ::logging ::formatter::base<boost::logging::default_,boost::logging::default_>, 1> destination_base = boost ::logging ::destination::base<boost::logging::default_,boost::logging::default_>, 1> lock_resource=boost::logging::lock_resource_finder::single_thread, 1> apply_format_and_write = boost ::logging ::format_and_write ::simple<boost::logging::optimize::cache_string_one_str<>>, 1> router_type=boost::logging::msg_route::simple<boost::logging::formatter::base<boost::logging::default_,boost::logging::default_>,boost::logging::destination::base<boost::logging::default_,boost::logging::default_>,boost::logging::lock_resource_finder::single_thread>, 1> formatter_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::formatter ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex>, 1> destination_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::destination ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex>, 1> formatter=boost::logging::formatter::idx_t<> 1> ] 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\sources\logutils.cpp(58) : error C2440: '<function-style-cast>' : cannot convert from 'const char [19]' to 'boost::logging::formatter::time' 1> No constructor could take the source type, or constructor overload resolution was ambiguous 1>c:\sources\logutils.cpp(58) : error C2780: 'void boost ::logging ::writer ::format_write < formatter_base ,destination_base ,lock_resource ,apply_format_and_write ,router_type ,formatter_array,destination_array>::add_formatter(formatter,const boost::logging::char_type *)' : expects 2 arguments - 1 provided 1> with 1> [ 1> formatter_base = boost ::logging ::formatter::base<boost::logging::default_,boost::logging::default_>, 1> destination_base = boost ::logging ::destination::base<boost::logging::default_,boost::logging::default_>, 1> lock_resource=boost::logging::lock_resource_finder::single_thread, 1> apply_format_and_write = boost ::logging ::format_and_write ::simple<boost::logging::optimize::cache_string_one_str<>>, 1> router_type=boost::logging::msg_route::simple<boost::logging::formatter::base<boost::logging::default_,boost::logging::default_>,boost::logging::destination::base<boost::logging::default_,boost::logging::default_>,boost::logging::lock_resource_finder::single_thread>, 1> formatter_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::formatter ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex>, 1> destination_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::destination ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex> 1> ] 1> c:\sources\thirdpartylibs\installedwin32\individual\boost \include\boost\logging\detail\format_write_detail.hpp(232) : see declaration of 'boost ::logging ::writer ::format_write < formatter_base ,destination_base ,lock_resource ,apply_format_and_write ,router_type,formatter_array,destination_array>::add_formatter' 1> with 1> [ 1> formatter_base = boost ::logging ::formatter::base<boost::logging::default_,boost::logging::default_>, 1> destination_base = boost ::logging ::destination::base<boost::logging::default_,boost::logging::default_>, 1> lock_resource=boost::logging::lock_resource_finder::single_thread, 1> apply_format_and_write = boost ::logging ::format_and_write ::simple<boost::logging::optimize::cache_string_one_str<>>, 1> router_type=boost::logging::msg_route::simple<boost::logging::formatter::base<boost::logging::default_,boost::logging::default_>,boost::logging::destination::base<boost::logging::default_,boost::logging::default_>,boost::logging::lock_resource_finder::single_thread>, 1> formatter_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::formatter ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex>, 1> destination_array = boost ::logging ::array ::shared_ptr_holder < boost ::logging ::destination ::base < boost ::logging ::default_,boost::logging::default_>,boost::logging::threading::mutex> 1> ] --snip-- 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
