FIREBREATH 1.6 -- VC2010 -- No logging with FBLOG_TRACE("StaticInitialize()", "INIT-trace");
settings
outMethods.push_back(std::make_pair(FB::Log::LogMethod_File, "U:/logs/PT.log")); ... FB::Log::LogLevel getLogLevel(){ return FB::Log::LogLevel_Trace; ...
changing "FBLOG_TRACE" to "FBLOG_INFO" logging to Logfile works. I don´t understand the reason.
回答1:
function not inserted in its respective area
FB::Log::LogLevel getLogLevel(){
return FB::Log::LogLevel_Trace; // Now Trace and above is logged.
}
Discription Logging here.

regenerate your project using the prep* scripts
open up Factory.cpp in your project. You need to define the following function inside the class definition for PluginFactory:

If you want to change the log level, you need to define the following in your Factory.cpp:
Referring to the above that means somewhere in "Factory.cpp". that´s incorrect. The description should say -->

I drag it from bottom of "Factory.cpp" to inside Class PluginFactory. Now it works as expected !!!

The entire purpose of having different log levels (FBLOG_FATAL, FBLOG_ERROR, FBLOG_WARN, FBLOG_INFO, FBLOG_DEBUG, FBLOG_TRACE) is so that you can configure which level to use and anything below that level is hidden. The default log level in FireBreath is FB::Log::LogLevel_Info, which means that nothing below INFO (such as DEBUG or TRACE) will be visible.
You can change this by overriding FB::FactoryBase::getLogLevel() in your Factory class to return FB::Log::LogLevel_Trace.
The method you'd be overriding is: https://github.com/firebreath/FireBreath/blob/master/src/PluginCore/FactoryBase.cpp#L78
The definition of the LogLevel enum: https://github.com/firebreath/FireBreath/blob/master/src/ScriptingCore/logging.h#L69
There was a version of FireBreath in which this didn't work; I think it was fixed by 1.6.0, but I don't remember for certain. If that doesn't work try updating to the latest on the 1.6 branch (which is currently 1.6.1 as of the time of this writing but I haven't found time to release yet)
