The Question & Background I'm a novice programmer with a few years of off and on experience with programing in General. I'm no expert but I am still a little bit off being a noob. What I have been trying to do is play MP3 files with the following code.
void loadMp3File(const char* filename)
{
mpg123_handle *mh;
unsigned char *buffer;
size_t buffer_size;
size_t done;
int err;
int channels, encoding;
long rate;
mpg123_init();
mh = mpg123_new(NULL, &err);
buffer_size = mpg123_outblock(mh);
buffer = (unsigned char*) malloc(buffer_size * sizeof(unsigned char));
mpg123_open(mh, filename);
mpg123_getformat(mh, &rate, &channels, &encoding);
int m_bits = mpg123_encsize(encoding);
int m_rate = rate;
int m_channels = channels;
/* decode and play */
for (int totalBtyes = 0 ; mpg123_read(mh, buffer, buffer_size, &done) == MPG123_OK ; ) {
totalBtyes += done;
}
/* clean up */
free(buffer);
mpg123_close(mh);
mpg123_delete(mh);
mpg123_exit();
}
What I have done thus far I've spend a few days messing around, with the Visual Studio files included with the source for mpg123. I changed and messed around with the additional dependices in the settings, with much trial and error I was able to produce a library file. Put simply it produced a mile of linker errors despite my attempts to fix it.
Conclusion My question is how do I fix this problem or should I make other considerations? Either way thank you in advance to anyone who takes the time to answer this question.

Just wanted to add that this question is entirely unrelated to one that marked this as a duplicate. It doesn't provide a clear or remotely meaningful description of the problem.
