I just started to learn the OpenAL. I have a problem when i try to compile a new code. it gives me a error:

#include <stdio.h>
#include <stdlib.h>
#include <GL/glut.h>
#include <AL/al.h>
#include <AL/alut.h>


#define NUM_BUFFERS 1
#define NUM_SOURCES 1
#define NUM_ENVIRONMENTS 1

ALfloat listenerPos[]={0.0,0.0,4.0};
ALfloat listenerVel[]={0.0,0.0,0.0};
Alfloat listenerOri[]={0.0,0.0,1.0, 0.0,1.0,0.0};

ALfloat source0Pos[]={ -2.0, 0.0, 0.0};
ALfloat source0Vel[]={ 0.0, 0.0, 0.0};

Aluint buffer[NUM_BUFFERS];
Aluint source[NUM_SOURCES];
ALuint environment[NUM_ENVIRONMENTS];

ALsizei size,freq;
ALenum format;
ALvoid *data;

void init(void)
{
alListenerfv(AL_POSITION,listenerPos);
alListenerfv(AL_VELOCITY,listenerVel);
alListenerfv(AL_ORIENTATION,listenerOri);

alGetError(); // clear any error messages

// Generate buffers, or else no sound will happen!
alGenBuffers(NUM_BUFFERS, buffer);

if(alGetError() != AL_NO_ERROR)
{
printf("- Error creating buffers !!\n");
exit(1);
}
else
{
printf("init() - No errors yet.");
}

alutLoadWAVFile("a.wav",&format,&data,&size,&freq);
alBufferData(buffer[0],format,data,size,freq);
alutUnloadWAV(format,data,size,freq);

alGetError(); /* clear error */
alGenSources(NUM_SOURCES, source);

if(alGetError() != AL_NO_ERROR)
{
printf("- Error creating sources !!\n");
exit(2);
}
else
{
printf("init - no errors after alGenSources\n");
}

alSourcef(source[0], AL_PITCH, 1.0f);
alSourcef(source[0], AL_GAIN, 1.0f);
alSourcefv(source[0], AL_POSITION, source0Pos);
alSourcefv(source[0], AL_VELOCITY, source0Vel);
alSourcei(source[0], AL_BUFFER,buffer[0]);
alSourcei(source[0], AL_LOOPING, AL_TRUE);


}

Omg, i'm using Microsoft C++ express to compile it. How come it can't detect the alc.h since it was already inside the AL folder. Any1 know how?

[Mihail121]

1. Use code tags around code, PLEASE.
2. Before "learning" OpenAL, learn your development environment of choice. The error points out that a file cannot be found and Visual Studio is pretty good at locating files, as long as you provide ALL necessary include paths to check.
3. Open alut.h, locate line 5, see how alc.h is included and what path should be added for this include to be located.

[iceboylsg]

after i locate the alc.h, another 14 errors come out=.=. Is it my code problem? i stuck here for a few hours=.=.

[Mihail121]

Yeah, that's your code now, nothing to do with OpenAL.

[poita]

Your first few errors are caused by you typing Alfloat instead of ALfloat. I'm assuming it's just a typo, but in case you aren't aware, C and most modern languages are case sensitive, so Alfloat =/= ALfloat.

[rouncer]

You gotta learn c before you can learn an api.

[iceboylsg]

lol...i ty

[iceboylsg]

sorry for my newbie question. After i correct all the errors, when i debug it, it comes out this:

what does this mean?

[poita]

It means you aren't linking to the OpenAL library.

[iceboylsg]

lol..i solved this prob..and another problem comes out=.=

fatal error LNK1104: cannot open file 'C:\Program.obj'

lol...what is this mean again=.=.....

[Mihail121]

It means the object file does not exist any more. Recompile, relink and you're done.

[iceboylsg]

omg..i'm getting crazy.....after relink and recompile, it come out again the error link 2019!!

it seems the error cannot be solved!!!..help=.=

[Mihail121]

Oh my God, I'm seriously getting somewhat aggressive:

Link the ALUT library as well.

is it related to the regsvr32 prob?

[iceboylsg]

lol.nth oledi..i know now thank you!!!!!!!!

[iceboylsg]

ahh...i have a very noob question. when we using the alutLoadWAVFile function. Where should i save the wav file? Is it i have to assign it first using fopen?
