Code::Blocks 13.12

[progleo]

Why does this work?

#include <iostream>
#include <string>
#include <fstream>
#include <limits>
#include "fcreate.h"


std::fstream& GotoLine(std::fstream& file, unsigned int num){
    file.seekg(std::ios::beg);
    for(int i=0; i < num - 1; ++i){
        file.ignore(std::numeric_limits<std::streamsize>::max(),'\n');
    }
    return file;
}

int main()
{
    std::string filename, trash, mname;
    int hp;

    std::cout << "Enter filename: ";
    std::cin >> filename;

    std::fstream monster(filename.c_str());

    monster >> trash >> mname;

    GotoLine(monster, 2);

    monster >> trash >> hp;

    monster.close();

    std::cout << mname << " has " << hp << " hp" << std::endl;
    return 0;
}

but when I add a class it doesn't

fcreate.cpp

#include <iostream>
#include "fcreate.h"

fcreate::fcreate()
{
    std::cout << "BUG";
}

Build messages:
In function `_start´:
undefined reference to `main´

I can't edit the 1st post that's why I made a new one. I can't even post a reply

Are you compiling and linking those two files simultaneously? Are you sure htat you do not just try to link second one alone?

[progleo]

I don't manually compile I use code::blocks build & run button, I fixed it by un-install code::block and install it back.

I have no idea why it didn't work before.

[MiiNiPaa]

Are both files are set to compile? Are they in the same project?

[progleo]

Yes, but I have no problem anymore I un-installed c::b and installed it back and I have no problems anymore.
