[Speex-dev] Problems with Speex Libary

[Werner Mandla]

Hello,

today I try to compile a test-file from the Documentation.
I link the libarys correct but have only one error in this line:
state = speex_encoder_init(&speex_nb_mode);

The error:
main.cpp|21|undefined reference to `speex_nb_mode'|

The linking libarys:
"libspeex.lib" "libspeexdsp.lib" 


I ask in more c++ boards, but nobody can help me.
Hopefully I ask the developer :)


sincerely yours, Werner Mandla

The code:

#include "speex/speex.h"
#include 

/*The frame size in hardcoded for this sample code but it doesn't have to be*/
#define FRAME_SIZE 160
int main(int argc, char **argv)
{
   char *inFile;
   FILE *fin;
   short in[FRAME_SIZE];
   float input[FRAME_SIZE];
   char cbits[200];
   int nbBytes;
   /*Holds the state of the encoder*/
   void *state;
   /*Holds bits so they can be read and written to by the Speex routines*/
   SpeexBits bits;
   int i, tmp;

   /*Create a new encoder state in narrowband mode*/
   state = speex_encoder_init(&speex_nb_mode);

   /*Set the quality to 8 (15 kbps)*/
   tmp=8;
   speex_encoder_ctl(state, SPEEX_SET_QUALITY, &tmp);

   inFile = argv[1];
   fin = fopen(inFile, "r");

   /*Initialization of the structure that holds the bits*/
   speex_bits_init(&bits);
   while (1)
   {
      /*Read a 16 bits/sample audio frame*/
      fread(in, sizeof(short), FRAME_SIZE, fin);
      if (feof(fin))
         break;
      /*Copy the 16 bits values to float so Speex can work on them*/
      for (i=0;i<frame_size;i++)>
         input[i]=in[i];

      /*Flush all the bits in the struct so we can encode a new frame*/
      speex_bits_reset(&bits);

      /*Encode the frame*/
      speex_encode(state, input, &bits);
      /*Copy the bits to an array of char that can be written*/
      nbBytes = speex_bits_write(&bits, cbits, 200);

      /*Write the size of the frame first. This is what sampledec expects but
       it's likely to be different in your own application*/
      fwrite(&nbBytes, sizeof(int), 1, stdout);
      /*Write the compressed data*/
      fwrite(cbits, 1, nbBytes, stdout);

   }

   /*Destroy the encoder state*/
   speex_encoder_destroy(state);
   /*Destroy the bit-packing struct*/
   speex_bits_destroy(&bits);
   fclose(fin);
   return 0;
}
