Hi. If I understand right the code, even if log is disabled, I do pay for constructing log messages. Am I right? If so why do you force this?
No, you donot pay.
BOOST_LOG(app) << "testing " << i << '-' << j << '-' << k;
Is the equivalent of:
if ( is_log_enabled(app) ) app_log() << "testing" << i ...;
But it is still taking up space; not to mention CPU usage doing a run-time check to see if a log is enabled. I think it is very important that we can choose to build with all logging code removed. This has been discussed before, and I thought you were going to include an alternative macro, something like: BOOST_LOG(app,"testing " << i << '-' << j << '-' << k); (Would that compile? If so I think this should be the main macro, and the above format the alternative.) Darren
