[Cppcms-users] question about booster::log

[chenshu <csf...@gm...>]

Hello,
   I tried booster::log today.If I added sink explicitly below,it worked 
fine,and I could see the log info in log file.

void init_log(){
   booster::shared_ptr<booster::log::sinks::file> f(new 
booster::log::sinks::file());
   f->open("my_log");
   booster::log::logger::instance().add_sink(f);
}

int main(int argc,char ** argv){

   try {
     init_log();
     BOOSTER_ERROR("module") << "Message " << 3.14159;
....
}

2011-10-13 06:18:44 GMT; module, error: Message 3.14159 (main.cpp:72)


   But if I configured it in config.js like so,I couldn't see any log 
info,only log file was created.

     "logging":{
     "level":"debug",
     "file":{
         "name":"km_log",
         "append":false,
         "max_files":100
     }
     }

I looked into your codes and found some code here:
     std::string log_file;
     if(!(log_file=settings().get("logging.file.name","")).empty()) {
         booster::shared_ptr<sinks::file> file(new sinks::file());
         int max_files=0;
         if((max_files = settings().get("logging.file.max_files",0)) > 0)
             file->max_files(max_files);
         bool append = false;
         if((append = settings().get("logging.file.append",false))==true)
             file->append();
         file->open(log_file);
         logger::instance().add_sink(file);
     }

It looked the same as mine code.So no idea now.
