Initialization problem

Hi,
I'm trying to use log4cxx for a project I'm working on. The problem is
when I try to load the logger as described in the tutorial like this:
LoggerPtr
GluePairUnitDlg::logger(Logger::getLogger("gluepai runitdlg"));

I get the following errors:

gluepairunit.cpp:4: error: no matching function for call to
'log4cxx::Logger::getLogger(const char [16])'
/usr/include/log4cxx/logger.h:295: note: candidates are: static
log4cxx::LoggerPtr log4cxx::Logger::getLogger(const
log4cxx::String&)
/usr/include/log4cxx/logger.h:316: note: static
log4cxx::LoggerPtr log4cxx::Logger::getLogger(const
log4cxx::String&, log4cxx::spi::LoggerFactoryPtr)

Now, If I change the loader for this:

LoggerPtr
GluePairUnitDlg::logger(Logger::getLogger(L"gluepa irunitdlg"));

I get this error:

gluepairunit.cpp:4: undefined reference to
`log4cxx::Logger::getLogger(std::basic_string<wcha r_t,
std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)'

I try to use the Constructor of a string like this

String tmp("gluepairunitdlg");
LoggerPtr GluePairUnitDlg::logger(Logger::getLogger(tmp));

And then I get this set of errors:

gluepairunit.cpp:4: error: no matching function for call to
'std::basic_string<wchar_t, std::char_traits<wchar_t>,
std::allocator<wchar_t> >::basic_string(const char [16])'
/usr/include/c++/4.2/bits/basic_string.tcc:233: note: candidates
are: std::basic_string<_CharT, _Traits,
_Alloc>::basic_string(typename
_Alloc::rebind<_CharT>:ther::size_type, _CharT, const _Alloc&)
[with _CharT = wchar_t, _Traits = std::char_traits<wchar_t>,
_Alloc = std::allocator<wchar_t>]
/usr/include/c++/4.2/bits/basic_string.tcc:226: note:
std::basic_string<_CharT, _Traits, _Alloc>::basic_string(const
_CharT*, const _Alloc&) [with _CharT = wchar_t, _Traits =
std::char_traits<wchar_t>, _Alloc = std::allocator<wchar_t>]

And if I try this:

String tmp(L"gluepairunitdlg");
LoggerPtr GluePairUnitDlg::logger(Logger::getLogger(tmp));

The string is created perfectly but the call to get logger gives me:

gluepairunit.cpp:5: undefined reference to
`log4cxx::Logger::getLogger(std::basic_string<wcha r_t,
std::char_traits<wchar_t>, std::allocator<wchar_t> > const&)'

I'm working on Ubuntu 8.04 Hardy, log4cxx version 0.9.7-6, gcc 4.2.3.
The IDE is kdevelop and the file is encoded as UTF-8.

I don't know if this is all the relevant information. Thank you for your
help

log4cxx 0.9.7 is obsolete and no longer supported. log4cxx 0.10.0 is
the current release.
