I'm having a problem when compiling the code below it says "undefined reference to 'readimagefile'" and it's moving me to another page or something I don't know. I've included all the libraries needed to run the code and the photo is in the same folder where the code is located. Please help I've researched a lot and I can't find a solution. Thank you!
#include<graphics.h>
#include<conio.h>
int main()
{
initwindow(800,600);
readimagefile("alien.jpg",0,0,200,200);
getch();
closegraph();
return 0;
}
