25 * \brief Simple pre-processor logging utility.
27 * Replaces LOG( lvl, x ) with "if(lvl <= LOG_LEVEL) std::cout << x << std::endl" when logging is active
28 * (LOG_LEVEL > 0 is defined). x is the level at which the message should be logged - if it is smaller or equal to
29 * LOG_LEVEL (which can be defined at compile-time for each file by passing option -DLOG_LEVEL=x to gcc)
30 * than the message is logged.
36 /// define LOG_LEVEL here if it is not already defined
45 /// write message msg to std::cout if x <= LOG_LEVEL
46 #define LOG(x, msg) if(x <= LOG_LEVEL) std::cout << msg << std::endl;
47 #define LOG3( x , msg1 , msg2 ) if(x <= LOG_LEVEL) std::cout << msg1, msg2 << std::endl;
51 #define LOG( x , msg )
52 #define LOG3( x , msg1 , msg2 )
