[Speex-dev] Some question about speexcodex 1.2 beta2 on linux

[r96128]

Hi,
I am an user of speex codec.Can I ask some question about the speexcodec 1.2beta2
on installed to linux(fedora 6)  thanks!

After I downloaded the latest version of codec
then I type the commands to install :

configure -prefix=/home/...../test -enable-shared -enable-static
make
make install

then I try to compile my encode.c
here is the encode.c of mine:
=====================================
#include <speex/speex.h>
#include <speex/speex_preprocess.h>
#include <stdio.h>

#define MAX_FRAME_SIZE 320

int main() {
        FILE *fin, *fout;
        short in[MAX_FRAME_SIZE];
        char cbits[200];
        int nbBytes = 0;
        void *state;
        SpeexBits bits;
        int m_frame_size;
        int m_channels = 1;

        // SpeeX encode options
        int m_bitrate = (8 << 10);
        int m_complexity = 3;
        int m_quality = 8;
        int m_encMode = 6;
        int m_iAGC = 0;
        int m_iDenoise = 0;

        SpeexPreprocessState *m_preProcesser;
        int nOff = 0, nOn = 1;
        int modex=30;
        speex_bits_init(&bits);
        state = speex_encoder_init(&speex_nb_mode);
        speex_encoder_ctl(state,SPEEX_RESET_STATE,NULL);
        speex_encoder_ctl(state,SPEEX_RESET_STATE,NULL);
        speex_encoder_ctl(state,SPEEX_GET_FRAME_SIZE,&m_frame_size);
        speex_encoder_ctl(state,SPEEX_SET_VAD, &nOff);
        speex_encoder_ctl(state,SPEEX_SET_DTX, &nOn);
        speex_encoder_ctl(state,SPEEX_SET_MODE,&m_encMode);
        speex_encoder_ctl(state,SPEEX_SET_BITRATE,&m_bitrate);
//      speex_encoder_ctl(state, SPEEX_SET_QUALITY, &tmp);

        m_preProcesser = speex_preprocess_state_init(m_frame_size, 8000);
        speex_preprocess_ctl(m_preProcesser, SPEEX_PREPROCESS_SET_DENOISE,
&m_iDenoise);
        speex_preprocess_ctl(m_preProcesser, SPEEX_PREPROCESS_SET_AGC, &m_iAGC);

        fin = fopen("test.pcm", "r+b");
        fout = fopen("out.spx", "w+b");

        if (fin == NULL || fout == NULL){
                printf("FILE open error!!\n");
                return 1;
        }

        while(1){
                fread(in, sizeof(short), m_frame_size, fin);
                if(feof(fin))
                        break;

                speex_bits_reset(&bits);

                if (m_preProcesser)
                        speex_preprocess(m_preProcesser, in, NULL);

                speex_encode_int(state, in, &bits);
                nbBytes = speex_bits_write(&bits, cbits, 200);

                fwrite(&nbBytes, sizeof(int), 1, fout);
#ifdef _DEBUG
                printf("Encode nbBytes: %d\n", nbBytes);
#endif
                fwrite(cbits, 1, nbBytes, fout);
                //fflush(fout); 
        }

        speex_encoder_destroy(state);
       speex_bits_destroy(&bits);
        fclose(fin);
        fclose(fout);
        return 0;
}
                       

=============================


then I used gcc or g++ to compile this file with the static libery
command:

gcc encode.c ../test/lib/libspeex.so

the result of compiling is ok
then when I run the program it shows

'./a.out: symbol lookup error: ./a.out: undefined symbol:
speex_preprocess_state_init

how can I compile the file?

thanks for the viewing for this mail
