linker problem

linker problem

• daniel kurtz

  No, I did not.
  
  Actually I used a MSDN sample code I fund at tis URL
  
  ms-help://MS.VSCC.v80/MS.MSDNQTR.v80.en/MS.MSDN.v80/MS.WIN32COM.v10.en/winsock/winsock/setsockopt_2.htm
  
  This snippet can be found under setsockopt with C++ flter in VS2005 help.
  
  All I did was to convert Main() into a subroutine. I christened it SocketPlusConnect
  It is a mnemonics issue for me.
  
  Thus getsockopt is a standard function.
  
  Thanks.

  Did you included Ws2_32.lib into the list of libraries that the linker should use
  
  SocketPlusConnect seams to be a function of your own, that has no implementation.

  Did you wrote your own definition for setsocketopt. The name is mangled by C++ but it should be declared as extern "C"!
  
  Did you really used the standard winsock2 header

  Thanks for the suggestion but the problem has not been resolved. I want to describe in detail what I did. Please review it. Perhaps I did something wrong.
  
  I found Ws2_32.lib in at least 4 directories in my computer and chose one of them: "C:\Program Files\Visual Studio 8\VC\PlatformSDK\Lib"
  
  Next I clicked on Project-->SocketCPlus Properties-->Configuration Properties-->Linker-->General in my Visual Studio 2005.
  
  SocketCPlus is just the asigned name for the project and the user defined function, you were correct, has name SocketPlusConnect.
  
  At Linker-->General I had a few options. First I changed "Ignore Import Library" from default "Yes" to "No." It was not very simple because a few times it reverted back to "Yes" but I persisted. Now it seems to have stuck.
  
  Next thing I entered the directory mentioned above into the slot: "Additional Library Directories" which was blank before.
  
  Then I changed "Use Library Dependency Inputs" from "No" to "Yes."
  
  I want to say that I made these two changes "Yes" to "No" and "No" to "Yes" just in case without real understanding but it seemed logical to me.
  
  I got the same 23 LNK errors.
  
  Please help.
  
  Thanks.
