C ++ Eclipse g ++：错误：./Matrix.o：没有这样的文件或目录：*** [MatrixSample]错误1

Question

I am trying to make a program that can manipulate matrixes and I am getting that error in Eclipse on Ubuntu 14.04. I searched on google and on stack over flow, but I did not find anything that I could understand and I am stuck. May anybody help me out with this please?

The complete error message:

14:29:27 **** Incremental Build of configuration Debug for project MatrixSample ****

Here is the code:

/*
 * Main.cpp
 */

#include "Matrix.hpp"

int main()
{
    Matrix<int> firstMatrix();
    return 0;
}

/*
 * Matrix.hpp
 *
 */

#ifndef MATRIX_H_
#define MATRIX_H_

template <typename T>
class Matrix
{
public:
    Matrix();
private:
    int nbrRows;
    int nbrColumns;
};

#include "Matrix.inl"

#endif /* MATRIX_H_ */

/*
 * Matrix.inl
 */

template <typename T>
Matrix<T>::Matrix()
:nbrRows(0), nbrColumns(0){}

I found what the problem was. I added .inl files as C++ Source file instead of adding it to C++ Header file. Now it's working fine.
