Hello, Steve,
  thank you for your response.
  in the application by using shared ACE lib. I did not write any code and did not define any class called Logger. I just put Logger after dynamic. do you think i need to write a class called Logger when I use static ACE lib.

      Hi Richard,
  Thanks for the PROBLEM-REPORT-FORM. I suspect you'll need to add the static service macros to ACE to set up the static service loading info. Please see C++NPv2 chapter 5 for details.

Subject: [ace-users] question about runtime configuration with the ACELogging Strategy

  ACE VERSION: 5.6.1
  HOST MACHINE and OPERATING SYSTEM:  Intel PC, Linux enterprise 5.0

  I am writing a application by using ACE lib.
I wrote a log application by using runtime configuration with the ACE logging strategy,
  the input configuration file is like the following.
  dynamic Logger Service_Object * ACE:_make_ACE_Logging_Strategy() "-s log.out -f STDERR|OSTREAM - INFO"
  in the application file , I use the code segment:
  if (ACE_Service_Config::open(argc,
                                                1) < 0)
  by this way, if I compile and link ACE to shared lib, it works well, I can create log.out and all message output to this log file.
  however, if I compile and link ACE to static lib, this way does not work, the log.out can not create. the error message is like the following:
  1 ACE(28532|2142880) LN::open_dll_ failed to open ACE. error: check log for detail.
  2. ACE(28532|2142880) unable to create service object for logger.
  I guess it is because no shared lib so I change the configuration file to the following.
  static Logger "-s log.out -f STDERR|OSTREAM -p INFO"
  then recompile and link my application which are using static ACE lib
  the log.out still can not be created. 
  error mesasge is :
  SG::initialize-service Logger was not located.
  even I change the fourth parameter of open to 0.
  could someboby tell me some solutions of how to solve this problem. that is by using static ACE lib to create log application.
  thanks in advance.
