Solved Linux - Error: undefined reference to `Tile::getHeight() const'

[Thaian Citizen]

Hello, when I try to compile I get the following error:

game.o: In function `Game::internalMoveCreature(Creature*, Direction, unsigned int)':
/root/****/source/game.cpp:1038: undefined reference to `Tile::getHeight() const'
/root/****/source/game.cpp:1038: undefined reference to `Tile::getHeight() const'
/root/****/source/game.cpp:1036: undefined reference to `Tile::getHeight() const'
/root/****/source/game.cpp:1040: undefined reference to `Tile::getHeight() const'
game.o: In function `Game:layerMoveCreature(unsigned int, unsigned int, Position const&, Position const&)':
/root/****/source/game.cpp:899: undefined reference to `Tile::getHeight() const'
collect2: error: ld returned 1 exit status
make[1]: *** [otserv] Error 1
make[1]: Leaving directory `/root/****/source'
make: *** [all] Error 2
******:~/****/source#

But my function getHeight() is defined properly?

Tile.cpp:

int32_t Tile::getHeight() const
{
    uint32_t height = 0;
    Item* iiItem = NULL;
    for(uint32_t i = 0; i < getThingCount(); ++i){
        iiItem = __getThing(i)->getItem();

        if(iiItem && iiItem->hasProperty(HASHEIGHT))
            ++height;
    }

    return height;
}

Tile.h:

// under this class, public
class Tile : public Cylinder
{
public:
int32_t getHeight() const;
...

game.cpp:

//this the lines calling the getHeight()
toTile = getTile(destPos);
 
    // ACERON TRYING TO IMPLEMENT STACKED BLOCK
    Tile* toPos = getTile(destPos.x, destPos.y, destPos.z);
    Tile* fromPos = getTile(currentPos.x, currentPos.y, currentPos.z);

    ReturnValue ret = RET_NOTPOSSIBLE;
    if(toTile != NULL){
     
        // Can't walk over items with height >= 2
        if (currentPos.z > destPos.z && toPos->getHeight() > 1);
            // not possible
        else if ((((toPos->getHeight() - fromPos->getHeight()) < 2)) ||
            (fromPos->hasHeight(3) && (currentPos.z == destPos.z)) ||
            ((currentPos.z < destPos.z) && (toPos->hasHeight(3) && (fromPos->getHeight() < 2)))) 
            ret = internalMoveCreature(creature, fromTile, toTile, flags);
    }

    if(ret != RET_NOERROR){
        if(Player* player = creature->getPlayer()){
            player->sendCancelMessage(ret);
            player->sendCancelWalk();
        }
    }

I know it's a simple misstake if there's one..
But I can't seem to find it
Your help is appreciated

RETURNVALUE_NOERROR

 

[Thaian Citizen]

are you referring to RET_NOERROR?
that can't be the reason, it is there

 

[mpa]

nvm my last post im wasted

you declare it int32_t but return uint32_t

 

[Thaian Citizen]

Nope

I had it at uint32_t before, produced same error. Now even changed it back to that and tried again, still produces same error..

Im getting frustrated everything seems right, like its a false error ??...

 

[mpa]

hmm probably some error with the makefile?

 

[Thaian Citizen]

so how would I check that/resolve that, I tried deleting, just left makefile.in and makefile.am there, because it wouldnt compile without.. after that it produced same error

 

[mpa]

First try to build your project in a new location, if that doesn't work, check the makefile if you link libraries in the correct order

 

[Thaian Citizen]

I did try to build it in a new location...

All I did was add an additional function to tile.cpp tile.h
I don't see how that simple thing can require to change the linking order :S

I really don't get behind that linking stuff... I mean I opened the makefile 1k lines and I don't even know what I would do there lol

edit: is there any way for me to provide more code/ info for you to detect the problem??

 

[mpa]

also double check if you included tile

maybe if I provide the full source files of the problem causing ones
