Hi Andrey,

The add_common_attributes function works for narrow-character logging. Wide-character counterpart is wadd_common_attributes. This may be the culprit, since the standard attributes are not found by the formatter and thus no log record passes to the sink. You should be able to see that by exceptions that are thrown by the formatter, unless you suppress them.

Thanks for your prompt reply. I changed the code to wadd_common_attributes() but the log still did not get created. Am I right in mentioning the strings like TimeStamp with L"TimeStamp" and ketwords::file_name = L"C:\\test\\test.log" during initialization. One warning that I get during compilation is the following. Does the following relevant to my problem? I noticed I got the same warning when compiling for normal character as well. c:\documents and settings\administrator\my

Hi Andrey,

Adding to the earlier emails, can you give me a small working sample for "wtext_file_backend". I am not sure where exactly messing with my code here. This is my Global Macro declaration - this is where I think the warning is getting thrown, is there a problem here?

BOOST_LOG_DECLARE_GLOBAL_LOGGER_INIT(bmr_log, sources::severity_logger_mt<>) { Log_Init();

sources::severity_logger_mt<> lg;

return lg; }

Logging sources should also be wide, so you should be using wseverity_logger_mt. I suggest you to build the library with the BOOST_LOG_USE_WCHAR_T macro defined. This will disable any narrow-character support in the library. Then you can try compiling your code and the parts that fail to link will highlight the places you have to modify in order to switch to wide character logging.

Hi, wseverity_logger_mt did the trick. Did not notice you mentioned it earlier. Thanks a lot for your great response. Can you also suggest something about the warning? Thanks again. Siva. On Sun, Aug 15, 2010 at 11:37 PM, Sivaram Kannan <siva.devel@gmail.com>wrote:

No luck with this too. I compiled with BOOST_LOG_USE_WCHAR_T. My program compiles without any problems but the log did not get created. Here is the actual warning that I am getting. Guess this is something to do with my global declaration.

The character type of attribute names indeed have to be the same as the logging character type. The file name can be specified either wide or narrow, regardless of the logging character type.

I think, you missed the warning message itself. The messages you posted only point to instantiations that led to the warning.
