My code has gotten large enough that I've had to split it into different object files. unfortunatly, I'm having difficulty resolving linker errors
here is the error(list) it gives:

make: *** [nimrl] Error 1
Here is my makefile
nimrl:
g++ -c -omain.o nimrl.cpp
g++ -c -omapgen.o mapgen.cpp
ld -onimrl -lncurses main.o mapgen.o
and here is the function loop mentioned in the error
int loop() //loop
{
char in;
int xoff,yoff,i;
cell map[mapmaxx][mapmaxy];
monster* pc = new monster(1);
pc->x=100;
pc->y=100;
pc->hp=10;
pc->symbol='@';
centermap(pc->x,pc->y,xoff,yoff);
mapgen(map,0);
centermap(pc->x,pc->y,xoff,yoff); //big:5,5,20
drawmap(map,maxx,maxy,xoff,yoff);
while (1)
{
input(pc,map);
out.print();
centermap(pc->x,pc->y,xoff,yoff);
drawmap(map,maxx,maxy,xoff,yoff);
mvprintw(pc->y-yoff+1,pc->x-xoff,"@");
move(pc->y-yoff+1,pc->x-xoff);
}
delete pc;
}
Thanks in advance
ps. How do oyu get code listings into a white box?
