decoder is undecleared !(need help as soon as possible)

[rezaee]

Hi
I am trying to compile continuous.c file with this command:

gcc -o continuous continuous.c     -DMODELDIR=\"`pkg-config --variable=modeldir pocketsphinx`\"     `pkg-config --cflags --libs pocketsphinx sphinxbase`

with this part of sample code:

hyp = ps_get_hyp(decoder);
if (strcmp(hyp, "play sound") == 0) {
      system("aplay asound.wav");
}
if (strcmp(hyp, "goodbye") == 0) {
      exit(0);
}

But it says "decoder is undecleared! " , also calling "ps_get_hyp" with too few arguments!

I can remember I did it before successfully but now, it doesn't work!
what is the problem?

OK!
I must say, I want my program does some actions when pocketsphinx recognized my command. for example if I said "hello" and pocketsphinx recognized it, pocketsphinx plays a wav file that says hello for response.

Before I could do it with above code, but last time when I trying that code, it gives me Undecleard decoder error!

What is the problem?
How can I do what I want?

Most likely PKG_CONFIG_PATH is not properly set as described in tutorial.
