Multiple definition of wxLogTrace linker error

[Navid]

Hi:

Initial attempts to build a test wxWidgets application using the CodeLite wizard failed with the log error below:

Following the recommenations in the thread below (with manually adding the libwxmsw28u_xrc.a library to the linker's libraries in the project):
http://codelite.org/forum/viewtopic.php ... ers+#p1225
I now get a linker error about duplication of wxLogTrace in log.cpp:

The objectionable lines of code being:

Code: Select all

...
void wxVLogTrace(const wxChar *mask, const wxChar *szFormat, va_list argptr)
  {
    if ( wxLog::IsEnabled() && wxLog::IsAllowedTraceMask(mask) ) {
      wxString msg;
      msg << _T("(") << mask << _T(") ") << wxString::FormatV(szFormat, argptr);
          
      wxLog::OnLog(wxLOG_Trace, msg, time(NULL));
    }
  }

/* line 207 */  void wxLogTrace(const wxChar *mask, const wxChar *szFormat, ...)
  {
    va_list argptr;
    va_start(argptr, szFormat);
    wxVLogTrace(mask, szFormat, argptr);
    va_end(argptr);
  }

...

and this has me baffled ... Any suggesitons would be appreciated!

Thanks,

Navid

Oops - solved - I had added libwxmsw28u_xrc.a rather than the debug version libwxmsw28ud_xrc.a ...
