[Log4cplus-devel] Problems linking log4cplus 1.0.3 in VisualStudio 2005 project

[heapifyman <hea...@gm...>]

Hello all,

I managed to successfully build log4cplus in Visual Studio 2005 and now
am trying to use it in my C++ project.

In my project settings, I added the log4cplus include dir to Additional
Includedirectories and also the msvc8\log4cplus_dll.Debug directory to
Additional Librarydirectories. Further, I added log4cplusD.lib to my
Linker-->Input-->Additional Dependencies (sorry if the setting's names
are not correct, I only have the German version here.

However, when building the project I get the following error in the
Linking step:
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)".

Am I missing anything in my includes or library dependencies?

Is there some documentation available on how to setup a VS 2005 project
with log4cplus support?

I'd appreciate any help.

Greetings,
Philip

Your project appears to be compiling without the "Treats wchar_t as built-in
type" option /Zc:wchar_t. The log4cplus MSVC projects are set up with the
option set so that wchar_t is a distinct type instead of alias for unsigned
short. You could try turning the option off in log4cplus project or (which I
would recommend) turning the option on in your application/project.

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.

You are using the DLL that is built without the UNICODE symbol defined,
the "Character Set" option. You need match the log4cplus DLL with the
settings of your project in this respect, too. If your project's
"Character Set" option is set to "Use Unicode Character Set" then you
will need to use log4cplus DLL from one of
log4cplus_dll.{Release,Debug}_Unicode directories.
