Linking issues - "redefined"

What IDE are you using?

If VC++7 or above, try enabling "ShowIncludes" in the Advanced section of the project properties. That will show you which files are being included... natch.

If not, try searching for "winsock2.h" and search "Entire Solution" and/or all the include directories in your path. Find all the files where it is included, and see if you include THOSE headers.

...

It could also be that you are linking more than one static library where the symbols have been defined, and you have a linker error.

codewarrior 9.4 (updated)

I am thinking about going to VC++ 2005 EE :(

as usual, show code [smile]

yeah... to Alpha_ProgDes you listen :)

...and maybe do a clean build. It's possible some .obj (.o) and .lib (.a) files contain the same symbols.

I have recompiled, rid my self of prior object code.

the code is quite simple, all I would have to do is

#include "winsock2.h"

~main~
{

anycall to a winsock function; /// errp function redefined.

}

error redefined - anycall

I have put this in an involved project, and a simple hello world program, same issues. Im quite put off with my linker right now.

Im almost certain its codewarrior specific. This is a conceptual problem, not a matter of syntax, and it has to do with my linker seeing double, where I have been only able to find one header file.

THIS IS A PROBLEM WITH SETTINGS AND LINKING ISSUES WITH CODEWARRIOR 9, not a code issue.

Checking out these lines from winsock2.h...

#ifndef _WINSOCK2API_#define _WINSOCK2API_#define _WINSOCKAPI_   /* Prevent inclusion of winsock.h in windows.h */

...this suggests that maybe you're including before ?

But I haven't looked through winsock2.h thoroughly... you may need first to define data types like DWORD and UINT.

[EDIT] woop ... look at this:

Lines 35-41:

/* * Pull in WINDOWS.H if necessary */#ifndef _INC_WINDOWS#include <windows.h>#endif /* _INC_WINDOWS */

Just do away with #include , if you have that in your header.

ill give it a shot, thanks.
