Because your code is wrong.

If you're using allegro, include only winalleg.h before allegro.h.

umperio, we need more info. I think that's what gillius is getting at.

Actually I think I'm a tad ugly, but some women disagree, mostly Asians for some reason.

#include <allegro.h>
#include <winalleg.h>
#include <winsock2.h> //or winsock.h.. whatever its called

Ah, yes, winalleg.h comes after allegro.h. But you should not include winsock2.h. winalleg already does it.

I'm using DevC++ and found that defining NOGDI define (-DNOGDI compiler option for MinGW) allows <allegro.h> and <windows.h> (or anything that includes it, like <winsock.h> and <vector>) to coexist. I don't know if it's proper solution, but it works for me all the time. :)

that removes the GDI Driver tho.
There's a command like "-__HIDE-W32API" also :o

Oscar, winalleg includes windows.h.

-D__GTHREAD_HIDE_WIN32API. But that one will do nothing here; it only stops the STL stuff from including windows.h when using GCC.

decsonic: Read it again. winsock2.h, not windows.h.

This is what I get when I compile, if I use only <winsock.h> instead of <winsock2.h> I get no errors.

Oh... so it may really be a problem with the #include order. Strange that the errors comes only with <winsock2.h>. Try to post your #include lines.

I made a program with allegro an winsock2, and I just included allegro.h and winalleg.h, and it worked. Including winsock2.h gives errors about redefinitions, so winalleg.h (or windows.h) already includes winsock2.h.

Quote:

-D__GTHREAD_HIDE_WIN32API. But that one will do nothing here; it only stops the STL stuff from including windows.h when using GCC.

decsonic: Read it again. winsock2.h, not windows.h.

ah sorry, forgot that he said msvc :P
I Never trust any files to already be included, winsock depends on windows.h.

The way i posted above should work tho

Ok, I'll say it once again:

#include <allegro.h>
#include <winalleg.h>
#include <winsock2.h> //or winsock.h.. whatever its called

just doesn't compile! Trust me, I've tried it. You MUST NOT include winsock2.h

what version of msvc do you have? It doesn't work with msvc6 (maybe an unpatched version).

Was testing that with mingw(Yes Brain dead atm - Insomnia)
checking with msvc, hmm see the problem..
winsock.h is included automaticly, but when you include winsock2 you get problems
