Thanks, Zhu. That's a solution, but expose a initialize method to the client exe is not so clean an not so smart. But if there isn't another solution, that will make it. :(
But I think the log4cxx is likely have some api for the user to query the intialize status. 2009/4/22 Lijuan Zhu <zhu.lij...@gmail.com> > Your project should have an entry point, like some Initialize method, if > you initalize the log4cxx there, the log4cxx should be initialized for all > other dlls. > > HTH, > Lijuan > > > On Wed, Apr 22, 2009 at 10:18 AM, yaohua xiao <bentry...@gmail.com> wrote: > >> Renny, Thanks for your replay! >> >> I already have a singleton class called "log4cxx_LogManager" to manage >> log4cxx >> in all the dlls. >> >> But I found that every dll will have a copy of that singleton class, >> so the singleton manager "log4cxx_LogManager" is not single in the >> mutiple dll enviromnents.If let the log4cxx_LogManager do the log4cxx >> initialized stuff, >> will initialize more than one times. >> >> Because log4cxx is compiled into a dll, it has only one copy in runtime. >> So I want my log4cxx_LogManager query if log4cxx is initialzed first, if >> not, initialize it. >> otherwise, use the logger directly. >> >> If log4cxx.dll has some initialize flag or api, the problem will simply >> solve. >> >> 2009/4/22 <renny.ko...@rubixinfotech.com> >> >>> >>> Why don't you simply create a singleton instance of a class that will >>> "manage" log4cxx for you? >>> >>> Then you can just query the singleton to see if it is initialized or >>> not... or even just call the "init()" method of the singleton in all your >>> DLL's... so the init will only happen once. >>> >>> Renny Koshy >>> President & CEO >>> >>> -------------------------------------------- >>> Rubix Information Technologies, Inc. >>> www.rubixinfotech.com >>> >>> >>> Hi all, >>> >>> I am new to log4cxx and have a mutiple dll project to use log4cxx for >>> some logging task. >>> My project has 3 dll modules: a.dll, b.dll, c.dll , all dlls need >>> logging. >>> >>> log4cxx needs some initialize code such like >>> BasicConfigurator::configure() >>> , load properties files, to prepare the logger.
