undefined reference

hi
can you show the kontrol function from both header and cpp ?
it says it has none that take 2 ints.
so i wonder if rastgele_dizi_elemani is an int ?

@SGaist said in undefined reference:

way, why do you have a folder named "
this is kontrol function :

int kontrol(int rastgele_eleman,int indis_vektor)// i1 i>0 durumu için kontrol
{
   int durum;
    if((gecici_haftaici_gunleritut.contains(rastgele_eleman+1)==true ||
            gecici_haftaici_gunleritut.contains(rastgele_eleman-1)==true ||
              secilen_ozelgunler[indis_vektor]==(rastgele_eleman-1) ||
                secilen_ozelgunler[indis_vektor]==(rastgele_eleman+1))==1)
    {
             durum=1;
    }
    else
    {
    durum=0;
    }


    return durum;
}

this is header file :

  int kontrol(int,int);

and rastgele_eleman is integer as random value between (0-31), indis_vektor is indeks of loop

by the way i changed return value as boolean and modified header file. but it did not work

Hi
Looks fine.
so is kontrol(int rastgele_eleman,int indis_vektor) in same file that you call it ?

i wonder why it says `Widget::kontrol(int, int)' in error when its clearly not part of Widget.

Did you declare it inside of a class in .h or or outside ?

i wonder if it should be
int Widget::kontrol(int rastgele_eleman,int indis_vektor)// i1 i>0 durumu için kontrol
{ ...
in the cpp

veysel.olgun

i am controling

veysel.olgun

namespace Ui {
class Widget;
}

class Widget : public QWidget
{
    Q_OBJECT
   

public:
    explicit Widget(QWidget *parent = 0);
    ~Widget();
    int boyut_hafta_sonu();
    int boyut_hafta_ici();
    QVector<int> aylarin_haftasonlarini_al() const;
    QVector<int> secilen_ayi_al();
    int sirasini_bul(QVector<int> &,int);
    void ozel_gun_nobeti_belirle();
    int kontrol(int,int);
    int kontrol_son_adim(int,int);
   
}

this is header file

mrjj

Ok :)
super, the issue is you forgot to mention Widget:: for its
implementation in cpp
You showed
int kontrol(int rastgele_eleman,int indis_vektor)// i1 i>0 durumu için kontrol
{
but it should have been

int Widget::kontrol(int rastgele_eleman,int indis_vektor)// i1 i>0 durumu için kontrol
{

since it belongs to the Widget class.

veysel.olgun

in addition that, my sirasini_bul function working in void Widget::nobet_gunleri_belirle()

 secilen_ay.erase(secilen_ay.begin()+sirasini_bul(secilen_ay,rastgele_dizi_elemani));

Thank you so much, how did i forget this :( it is working now. thank you for all of you

mrjj

@veysel.olgun
