Single stepping I found the following line from the global macro sources::wseverity_logger_mt<> lg; <=================== is not creating the lg object at all. What is the problem in the release mode?? As a summary of the problem, * An exe build in debug/release mode is working properly. * This application is a dll. * The same dll is working properly in debug mode. Thanks, Siva.

Hi,

On further investigation, I have narrowed down the issue to this line.

sources::wseverity_logger_mt<> &lg = ::get_my_log();  <================

This line is not returning the lg object from Global Macro.

BOOST_LOG_DECLARE_GLOBAL_LOGGER_INIT(my_log, sources::wseverity_logger_mt<>) {        Log_Init();        sources::wseverity_logger_mt<> lg;        return lg; }

This is not working properly only in release mode and working well in debug mode. Environment I am using is VC++ 2008. What am I missing??

Thanks, Siva.

Hi,

I have been using boost log with two of my projects, one an VC++ 2008 exe and another a VC++  DLL. Boost log was working as expected in the Debug mode. But when I compiled the projects in release mode, the boost log with the exe is not logging anything on the file and the dll is creating an access violation. Following is the call stack which is throwing the error.

cnbc.dll!boost::log_mt_nt5::sources::basic_logger<wchar_t,boost::log_mt_nt5::sources::wseverity_logger_mt<int>,boost::log_mt_nt5::sources::multi_thread_model<boost::shared_mutex>

I have compiled the boost in release mode and as shared. Following is the command I used. , .\bjam.exe --with-log --with-filesystem --with-system --with-date_time --with-thread --with-regex define=BOOST_ALL_DYN_LINK variant=release link=shared stage

What am i doing wrong here??

Thanks, Siva.

Hi,

Do I get it right that you built Boost.Log as dll?

I have a DLL application to which Boost.Log is linked with. I tried building the boost with both options linkage=static, linkage=shared.

If so, please elaborate what you mean by "not creating the lg object at all". Does execution reach this line? If not, then what happens before it?

Execution does reaches this line. But I could not see any instance getting created in the Locals tab. I repeat the point that this works well in the debug mode.

I bet it is somehow related to the Log_Init function you call before it.

I am not very sure. Here is the function. I am calling this function from the BOOST_LOG_DECLARE_GLOBAL_LOGGER_INIT. void Log_Init() { boost::function< void (std::wostream&, boost::log::wrecord const&) > formatter = boost::log::formatters::wstream << boost::log::formatters::date_time< boost::posix_time::ptime >(L"TimeStamp") << L" *" << boost::log::formatters::attr< int

(L"Severity") << L"* " << boost::log::formatters::wmessage();

boost::shared_ptr< sinks::synchronous_sink<boost::log::sinks::wtext_file_backend> > sink = boost::log::winit_log_to_file( keywords::file_name = L"C:\\logtst.log", // file name pattern keywords::rotation_size = 1 * 1024 * 1024, // rotate files every 1 MiB... keywords::open_mode = std::ios_base::app, keywords::severity = debug, keywords::auto_flush = true ); sink->locked_backend()->set_formatter(formatter); // Register common attributes boost::log_mt_nt5::wadd_common_attributes(); } What am I missing here? Thanks, siva.
