[Openal] Re: compiling using g++

[Paul Tawk]

I have a file main.cpp in which i copied a file from the OpenAL tutorial for linux. I use the linux shell and the g++ compiler, but maybe i shoud link the openAL files when compiling.
   
  I tried the statment:
   
  g++ -Wall -D__LINUX_OSS__ -o main main.cpp
   
  what additional commands should i include in my statment?
   
  best regards
   
   
   
   
  Below is the ccode i used in main.cpp
   
  #include <conio.h>
#include <time.h>
#include <stdlib.h>  #include <al/al.h>
#include <al/alc.h>
#include <al/alu.h>
#include <al/alut.c>

// Buffers hold sound data.
ALuint Buffer;

// Sources are points of emitting sound.
ALuint Source;

// Position of the source sound.
ALfloat SourcePos[] = { 0.0, 0.0, 0.0 };

// Velocity of the source sound.
ALfloat SourceVel[] = { 0.0, 0.0, 0.1 };

// Position of the listener.
ALfloat ListenerPos[] = { 0.0, 0.0, 0.0 };

// Velocity of the listener.
ALfloat ListenerVel[] = { 0.0, 0.0, 0.0 };

// Orientation of the listener. (first 3 elements are "at", second 3 are "up")
ALfloat ListenerOri[] = { 0.0, 0.0, -1.0,  0.0, 1.0, 0.0 };


ALboolean LoadALData()  {      // Variables to load into.        ALenum format;      ALsizei size;      ALvoid* data;      ALsizei freq;      ALboolean loop;        // Load wav data into a buffer.        alGenBuffers(1, &Buffer);        if (alGetError() != AL_NO_ERROR)          return AL_FALSE;        alutLoadWAVFile("wavdata/Footsteps.wav", &format, &data, &size, &freq, &loop);      alBufferData(Buffer, format, data, size, freq);      alutUnloadWAV(format, data, size, freq);        // Bind buffer with a source.        alGenSources(1, &Source);        if (alGetError() != AL_NO_ERROR)          return AL_FALSE;        alSourcei (Source, AL_BUFFER,   Buffer   );      alSourcef (Source, AL_PITCH,    1.0f     );      alSourcef (Source, AL_GAIN,     1.0f     );      alSourcefv(Source, AL_POSITION, SourcePos);      alSourcefv(Source, AL_VELOCITY, SourceVel);      alSourcei (Source, AL_LOOPING,  AL_TRUE  );        // Do an error check and return.        if (alGetError() !=
 AL_NO_ERROR)          return AL_FALSE;        return AL_TRUE;  }  

void SetListenerValues()  {      alListenerfv(AL_POSITION,    ListenerPos);      alListenerfv(AL_VELOCITY,    ListenerVel);      alListenerfv(AL_ORIENTATION, ListenerOri);  }    void KillALData()  {      alDeleteBuffers(1, &Buffer);      alDeleteSources(1, &Source);      alutExit();  }  
   

int main(int argc, char *argv[])  {      // Initialize OpenAL and clear the error bit.      alutInit(NULL,0);      alGetError();        // Load the wav data.      if (LoadALData() == AL_FALSE)          return 0;        SetListenerValues();        // Setup an exit procedure.      atexit(KillALData);        // Begin the source playing.      alSourcePlay(Source);        // Loop      ALint time = 0;      ALint elapse = 0;        while (!kbhit())      {          elapse += clock() - time;          time += elapse;            if (elapse > 50)          {              elapse = 0;                SourcePos[0] += SourceVel[0];              SourcePos[1] += SourceVel[1];              SourcePos[2] += SourceVel[2];                alSourcefv(Source, AL_POSITION, SourcePos);          }      }          return 0;  }
