[vbox-dev] Logging in Custom COM Implementations

Thanks.

I went through and moved all of the "Logging.h" includes to the top of
each *.cpp and *.h files, but the classes are still not logging to the
main group.  I am creating a debug build.  Before, I thought the
framework was creating new groups for each class, but now I understand
otherwise.

I went back and re-read the wiki and the headers, and I replaced the
"LogAlways" function calls with:

LogIt(LOG_INSTANCE, RTLOGGRPFLAGS_LEVEL_1,
LOG_GROUP_MAIN,("VBox.Main.Foo<functionName>: The address of this:
0x%08x\n", this));

I ensured that the following log-pertinent variables were set during the build:
VBOX_WITH_R0_LOGGING=1
BUILD_TYPE="debug"


The following logging variables were set:
VBOX_WITH_R0_LOGGING=1
VBOX_LOG_FLAGS=
VBOX_LOG=all
VBOX_LOG_DEST=stderr


The following log files were created:
2012-10-18-16-56-08.094-VBoxManage-23048.log
2012-10-18-16-56-08.097-VBoxSVC-23056.log
2012-10-18-16-56-09.018-VBoxHeadless-23067.log
2012-10-18-16-56-08.096-VBoxXPCOMIPCD-23051.log
2012-10-18-16-56-09.015-VBoxTestOGL-23063.log
2012-10-18-16-56-09.072-VBoxManage-23093.log


I was expecting all the messages to appear in any of the files
created, but the only logging message that happens is when the COM
interface gets initialized.  I grep'ed through the files and I found
only one instance of the "Foo" logging messages.  After the interface
is initialized, none of the other LogIt messages are logged.

Is there anything else that I can try?  Thanks for your help.
