http://code.google.com/p/google-glog/issues/detail?id=4

i've tried to use this header in my qt project and get linker error:
CMakeFiles/test.dir/myerror.cpp.o: In function
`operator<<(std::basic_ostream<char,
std::char_traits<char> >&, wchar_t const*)':
/opt/google/include/glog/logging.h:1093: multiple definition of
`operator<<(std::basic_ostream<char, std::char_traits<char> >&, wchar_t
const*)'
CMakeFiles/test.dir/xmlcheckthread.cpp.o:/usr/include/QtCore/qglobal.h:1499:

std::allocator<wchar_t> > const&)':
/home/aeon/projects/shalficky/qt_client/wchar_log.h:19: multiple definition

CMakeFiles/test.dir/xmlcheckthread.cpp.o:/home/aeon/projects/shalficky/qt_client/wchar_log.h:19:

including header in logging.h gives me same result.
is there any way to resolve this problem?

Ah, I think I forgot to add "inline" for the two operators.

#ifndef WCHAR_LOGGING_H_
#define WCHAR_LOGGING_H_

#include <wchar.h>

#include <iostream>
#include <string>

inline std::ostream& operator<<(std::ostream& out, const wchar_t* str) {
size_t len = wcsrtombs(NULL, &str, 0, NULL);
char* buf = (char*)malloc(len + 1);
buf[len] = 0;
wcsrtombs(buf, &str, len, NULL);
out << buf;
free(buf);
return out;
}

inline std::ostream& operator<<(std::ostream& out, const std::wstring& str)
{
return operator<<(out, str.c_str());
}

#endif // WCHAR_LOGGING_H_

Please let me know if this doesn't solve your issue.

I got a simmilar problem, with operator ==
The code suggested doesn't fix my problem...
When will google test support wchar/wstring?
I'm using VS2012 ultimate.
