Re: [Boost-users] boost logging from shared libraries

I have some dll's that have their own logs (each dll has a distinct
namespace), they can be enabled/disabled with enable_log()/disable_log().
The main program has yet another set of logs. Just make sure that you have
the proper appender for your dll logs. Sorry if this is not relevant to your
problem.

Subject: [Boost-users] boost logging from shared libraries

First, I wasn't sure where would be the most appropriate place to post this
question, so I apologize if it's gone to the wrong place.

I'm trying to figure out how to put logging statements in some shared
libraries which are then controlled via manipulate_logs() calls an the
executable that uses the libraries. It appears, after some rudimentary
experiments, that this does not work, and I was hoping to find out if there
is a way to do it.

The logging system, of course, does log manipulation using log names and
regular expression matching. As such, I assumed that logs were statically
allocated and, in some way, all registered with some central registry which
made them all available via their names.

Stepping through logging calls in the libraries seems to indicate that
logging code is being accessed and, as far as I can tell, the logs are
"enabled" and, in fact, trying  to log messages (to cout, for what it's
worth). However, I don't see anything printed except for log messages
genereted from the executable's source code.

So, is what I'm trying to do even feasible? I would love to be able to have
diagnostics built into my libraries which I could dis/enable as necessary
from the executive level. Hopefully I'm just missing something simple.
Thanks.
