Sup peeps, hope you guys can give a mate a hand with this default constructor problem. I get this error when i instantiate a class:
error LNK2019: unresolved external symbol...

This is my LavaLand.h

...

class LavaLand 
{

    highscore &h;

public:

    LavaLand();

    void setup();

};


...

LavaLand.cpp

void LavaLand::setup()
{       
    ...
    h.scoreboard(getScore());

}

I call this setup() in my Game.cpp

void Game::update()
{
        switch (myInput) {

        case 1: {
            LavaLand ll;   <--------- error
            ll.setup()
            break;
        }

}

It has a default constructor but i'm thinking theres something wrong with it though. Hope someone here could help. If you need more code please let me know.
Cheers

If you want LavaLand to have a default generated constructor then you need to get rid line 8 in LavaLand.h. You could also just change line 8 to LavaLand() {}; to make a default constructor yourself.

I've actually tried this. When i remove it an error stating " 'Lavaland': no appropriate default constructor available"

or if i simply code it as LavaLand() {}; i'd get an error of..."
Syntex error: '{'
'Lavaland::h' must be initialized in constructor base/member initializer list.
See declaration of 'Adventure::h

which prompted me to put highscore &h in the list of

LavaLand():
    {
        highscore &h;
    }

but, that too didn't work.

You have a reference member (highscore) in LavaLand and that needs to be initialized upon creation. Either remove the reference or change the constructor to take in a value to initialize highscore.

I'd like to keep the reference so i've initialized by...

class LavaLand
{

public:
    highscore &h;

    Lavaland(highscore &hs) :
        h(hs)
    {}

but it results in the same error " 'Lavaland' : No appropriate default constructor available"

i see that i forgot to call the right LavaLand ll; should be LavaLand ll(hs)
