Help in c++, Using itpp library

[saimanojpd]

Hi,

I am trying to model a communication channel in c++. I am using Eclipse Galileo IDE. The code is given below

#include <itpp/base/vec.h>
#include <itpp/itbase.h>
#include <itpp/itcomm.h>
 
 
 
using namespace itpp;
using namespace std;
 
using std::cout;
using std::endl;
 
 
template<class d>
class itpp::Vec< d >;
 
 
int main()
{
  //Scalars
  int N;
  double N0;
 
  //Vectors
  itpp::bvec bits, dec_bits;
  itpp::vec symbols, rec;
 
  //Classes
  itpp::BPSK bpsk;  //The BPSK modulator/demodulator class
  itpp::BERC berc;  //The Bit Error Rate Counter class
 
  //Init
  N = 500000; //The number of bits to simulate
  N0 = 1;     //0 dB SNR
 
  //Randomize the random number generator
  RNG_randomize();
 
  //Generate the bits:
  bits = randb(N);
 
  //Do the BPSK modulation
  bpsk.modulate_bits(bits, symbols);
 
  //Add the AWGN
  rec = symbols + sqrt(N0 / 2) * randn(N);
 
  //Decode the received bits
  bpsk.demodulate_bits(rec, dec_bits);
 
  //Count the number of errors
  berc.count(bits, dec_bits);
 
  //Print the results
  cout << "There were " << berc.get_errors() << " received bits in error." << endl;
  cout << "There were " << berc.get_corrects() << " correctly received bits." << endl;
  cout << "The error probability was " << berc.get_errorrate() << endl;
  cout << "The theoretical error probability is " << 0.5*erfc(1.0) << endl;
 
  //Exit program:
  return 0;
 
}

I am getting the following error
../main.cpp:22:13: error: specialization of ‘template<class Num_T> class itpp::Vec’ in different namespace
/software/itpp-4.2.0_suse11_1/64/include/itpp/base/factory.h:41:29: error: from definition of ‘template<class Num_T> class itpp::Vec’
../main.cpp:22:13: error: partial specialization ‘itpp::Vec<T>’ does not specialize any template arguments

line 22 &23 : template<class d>
class itpp::Vec< d >;

you can find vec.h in the following link
http://itpp.sourceforge.net/current/...pp_1_1Vec.html

if I remove those lines it is giving many errors. undefined reference to itpp::vec<>...

Please suggest me what to do. How to compile in console (in linux, using gcc compiler) by specifying lib path

Lines 14 and 15 server no purpose and should be removed. Then post the errors you are getting so we can see what might be causing that
