dev-cpp-users Mailing List for Dev-C++

dev...@li..., Most people stumble through their entire lives with out finding something to strive for. <a href="http://goo.gl/tdgjt">http://goo.gl/mP8qn</a>

So - have you done any ASAP search on Google?

Have you done any ASAP check what libraries you are linking?

Exactly what, have you ASAP actually done?

By the way - when you get a linker error, what is your ASAP view regarding 
compiler or linker problem? Did you ASAP consider telling us what your 
linker was ASAP instructed to do?

 pls help me resolve the linker error while working with OpenAl 1.1 in dev
c++
here is the code::::::::::::::::::::::::


#include <iostream>

#include "Al/al.h"
#include "Al/alc.h"

//#include <alc.h>

using namespace std;

using namespace std;
int main()
{
    ALCdevice *dev[2];
    ALCcontext *ctx;
    ALuint source, buffers[3];
    char data[5000];
    ALuint buf;
    ALint val;

    dev[0] = alcOpenDevice(NULL);
    ctx = alcCreateContext(dev[0], NULL);
    alcMakeContextCurrent(ctx);

    alGenSources(1, &source);
    alGenBuffers(3, buffers);

    /* Setup some initial silent data to play out of the source */
    alBufferData(buffers[0], AL_FORMAT_MONO16, data, sizeof(data), 22050);

    /* If you don't need 3D spatialization, this should help processing
time */
    alDistanceModel(AL_NONE);

    dev[1] = alcCaptureOpenDevice(NULL, 22050, AL_FORMAT_MONO16,
sizeof(data)/2);

    /* Start playback and capture, and enter the audio loop */
    alSourcePlay(source);

the
        * number of frames, not bytes) */

        /* Make sure the source is still playing */
        alGetSourcei(source, AL_SOURCE_STATE, &val);

        if(val != AL_PLAYING)

    }

    alcMakeContextCurrent(NULL);
    alcDestroyContext(ctx);
    alcCloseDevice(dev[0]);

    return 0;
}



errors are such as:::::::::::::::::::::::




  [Linker error] undefined reference to `_imp__alcOpenDevice'
  [Linker error] undefined reference to `_imp__alcCreateContext'
  [Linker error] undefined reference to `_imp__alcMakeContextCurrent'

and many others all are linker error::
