I’m using MSVC 2008 Express Edition. I downloaded the SVN head

to use log4cxx in one project without much problem, however, I then

again tried to integrate log4cxx and am getting a couple of errors

I built the log4cxx.lib both statically and dynamically and the
above output is when I use the shared lib, I’ve also added the Pre-
processor directive LOG4CXX_STATIC.
I’ve done everything I can think of to get this right and this
mailing list is my last resort ☺ I’d hate to waste your time.

You should only set LOG4CXX_STATIC when you are linking against a
static log4cxx library. Your message suggests that you set and tried
to link against a shared library which I would guess would result in
the types of messages that you see (I'd expect a declspec(import) to
show up in the method signature if LOG4CXX_STATIC was not set). Could
you confirm that your LOG4CXX_STATIC setting is consistent with the
type of log4cxx library that you are linking against?
