Re: [Log4cplus-devel] linking error

[drkmkzs <dr...@gm...>]

Thank for help,

But i was explicitely linking with lib4cplusU DLL when linking my
application with my static lib.

Indeed my error was to forget to add some cmake definition for unicode in
my cmake, as in the examples...

So after that, it was ok except my app didn't compile, when logging some
trace using glibmm methods...

So for the moment, I have recompiled log4cplus without unicode support,
removed the definitions in my cmake, and all compile well  (except for some
bad things from my side). What is the unicode option for ? I guess to treat
specific type as unicode compliant types ?
