[Log4cplus-devel] LOG4CPLUS_DEBUG expansion fails when DEBUG macro is defined

[Chernyshev V. <ast...@ro...>]

Hello.

While testing log4cplus with default-generated Xcode project on OS X, 
I've found out that any usage of LOG4CPLUS_DEBUG immediately produces 
very strange compilation errors. After examing this problem I've noticed 
that Xcode defines DEBUG macro to 1 for debug builds. As LOG4CPLUS_DEBUG 
is defined like:
     LOG4CPLUS_MACRO_BODY (logger, logEvent, DEBUG)
it is obvious that expanding this macro will fail later.

I have fixed it this way locally: https://gist.github.com/3643384 It 
somewhat uglifies the code, but predefined DEBUG_LOG_LEVEL macro is much 
less common than DEBUG/NDEBUG macro pairs.
