Everytime I'm going to use external sources I get: collect2. exe: error ld returned 1 exit status

Question

For example this code, I create a new project in codeblocks, add these files, enable the header file and when trying to run it i get:

-------------- Build: Debug in date (compiler: GNU GCC Compiler)---------------

mingw32-g++.exe -Wall -fexceptions -g -std=c++11 -I..\date -c "C:\Users\kairenne\Documents\programming\chapter 8\monster_generation\date\main.cpp" -o obj\Debug\main.o mingw32-g++.exe -o bin\Debug\date.exe obj\Debug\Date.o Date.h.gch obj\Debug\main.o Date.h.gch: file not recognized: File format not recognized collect2.exe: error: ld returned 1 exit status Process terminated with status 1 (0 minute(s), 1 second(s)) 1 error(s), 0 warning(s) (0 minute(s), 1 second(s))

Date.h

#define DATE_H

class Date
{
private:
    int m_year;
    int m_month;
    int m_day;

public:
    Date(int year, int month, int day);

    void SetDate(int year, int month, int day);

    int getYear() { return m_year; }
    int getMonth() { return m_month; }
    int getDay()  { return m_day; }
};

#endif

Date.cpp

// Date constructor
Date::Date(int year, int month, int day)
{
    SetDate(year, month, day);
}

// Date member function
void Date::SetDate(int year, int month, int day)
{
    m_month = month;
    m_day = day;
    m_year = year;
}

Main.cpp

#include "Date.h"

using namespace std;

int main()
{
    Date test(2000, 05, 10);
    return 0;
}

You should never compile or link header file. So remove that Data.h.gch from your linker's command and you'll be fine.

If it's done automatically for you in your IDE, disable "precompiled header" option.
