My apologies if I've posted this in the wrong section. I've read through other posts about Ogg and the documentation on the Ogg website to see if I could find anything that would help, but I was unsuccessful.
I've been trying to learn how to use the Ogg Vorbis SDK, but whenever I attempt to compile code I get errors. I've checked to make sure the header file, libraries, and DLL's are in the correct locations (to my knowledge they are). I am using MinGW with Dev-C++.
When I attempt to compile the some of the example included with the SDK, such as this code:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include <math.h>

#include <io.h>
#include <fcntl.h>

#endif

stream of packets */

settings */

I've alos tried compiling the code from Anthony "TangentZ" Yuen's article
Introduction to Ogg Vorbis with the same errors.
Any help you can provid is greatly appreciated.
