You're right about it being a settings problem. Here you have two (or possibly more) chunks of code you're attempting to link that have inconsistent dependencies on the C run time library. Note that there are a) LIB b) DLL versions of the CRT and they come in c) Release d) Debug versions. This is a debug build (note the trailing D). BUT, one chunk of code is importing symbols from the DLL CRT and the other from the LIB CRT. Thus the symbol redundancy. Use one or the other but not both and your application should link.

  Subject: error LNK2005 - already defined stuff...

  Does this look familar to anyone using MV6++:

  MSVCRTD.lib(MSVCRTD.dll) : error LNK2005: _malloc already defined in LIBCD.lib(dbgheap.obj)

  LINK : warning LNK4098: defaultlib "MSVCRTD" conflicts with use of other libs; use /NODEFAULTLIB:library
  Debug/PA_Server_Agent.exe : fatal error LNK1169: one or more multiply defined symbols found
  Error executing link.exe.

  I've done the following :

  my preprocessor settings are :
          WIN32,_DEBUG,_CONSOLE,_MBCS,NODEFAULTLIB:library

  my link object/library modules are:
          winmm.lib ws2_32.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib

  In my project I've encluded libcurl.lib

  For some reason I think it has to do with the run time library's and mucking around with debug and release version, under C/C++ tab -> Code Generation -> Use Run-Time Library -> ????

  Tell me if I'm way off here but maybe someone has already delt with this issue and can save me a lot of time :)

  Thanks
  Ben
