Thanks for the quick answer, unfortunately it didn't help.
If I recompile log4clus with "/Zc:wchar_t-" (which my project uses, as
it is an extension of another project that uses that setting...) I get
linking errors, the first one being:
error LNK2019: Verweis auf nicht aufgelöstes externes Symbol
""__declspec(dllimport) public: void __thiscall
log4cplus::Logger::forcedLog(int,class std::basic_string<unsigned
short,struct std::char_traits<unsigned short>,class
std::allocator<unsigned short> > const &,char const *,int)"
(__imp_?forcedLog@Logger@log4cplus@@QAEXHABV?$basic_string@GU?$char_traits@G@std@@V?$allocator@G@2@@std@@PBDH@Z)"
in Funktion ""public: __thiscall
Plateau::MyPlugin_impl::MyPlugin_impl(void)"
(??0MyPlugin_impl@Plateau@@QAE@XZ)".

which seems to be the same as in my first posting.

If I use log4cplus in standard settings "/Zc:wchar_t" and change my
project to that same setting, I get the following linking error:
error LNK2019: Verweis auf nicht aufgelöstes externes Symbol
""__declspec(dllimport) public: void __thiscall
log4cplus::Logger::forcedLog(int,class std::basic_string<wchar_t,struct
std::char_traits<wchar_t>,class std::allocator<wchar_t> > const &,char
const *,int)"
(__imp_?forcedLog@Logger@log4cplus@@QAEXHABV?$basic_string@_WU?$char_traits@_W@std@@V?$allocator@_W@2@@std@@PBDH@Z)"
in Funktion ""public: __thiscall
Plateau::MyPlugin_impl::MyPlugin_impl(void)"
(??0MyPlugin_impl@Plateau@@QAE@XZ)".

I'm really new to this whole C++ logging stuff (and c++ in general) so
I'm really a little confused what's going on here.

I'd appreciate it if you had any more ideas.
