I can't get PR_LOG log messages to print in SeaMonkey. I set the environment variables as described in prlog.h, but I still don't (normally) see any output. I also notice the following phenomenon: if, in gdb, I do a "break main" before running apprunner, I notice at the time main runs that _pr_initialized is 1, but logFile is NULL. Tracing through things, this is why no log information gets printed; PR_LogPrint automatically returns without doing anything if logFile is NULL. This behavior happens whether NSPR_LOG_FILE is set or not. NSPR_LOG_MODULES is set to 'nsComponentManager:5'. If I manually do 'set logFile = _pr_stderr' in gdb after 'break main', I see all the PR_LOG messages I expect. (I'm not sure I have the NSPR version number right; it's the one you get when you pull SeaMonkeyAll from CVS. I'm building NSPR in the SeaMonkey tree.)

Accepted the bug and cc list.

See the following code fragment for technique in using PR_LOG(). static void UserLogStuff( void ) { PRLogModuleInfo *myLM; PRIntn i; myLM = PR_NewLogModule( "userStuff" ); if (! myLM ) { printf("UserLogStuff(): can't create new log module\n" ); return; } PR_LOG( myLM, PR_LOG_NOTICE, ("Log a Notice %d\n", 1 )); for (i = 0; i < 10 ; i++ ) { PR_LOG( myLM, PR_LOG_DEBUG, ("Log Debug number: %d\n", i)); PR_Sleep( 300 ); } } /* end UserLogStuff() */
