Hi,
I am a newbie to graphics programming and wanting to use DJGPP for =
my graphics programming. I want to know if someone can just help me and =
write to me a simple program which can bascially plot a pixel on the =
screen, I should be able to manage with the algorithms myself.
I have done my programs in TC and used the following to plot points.
#include <graphics.h>
void main()
{
int gd,gm;
=20
detectgraph(&gd,&gm);
initgraph(&gd,&gm,"d:\\tc\\bgi");
putpixel(10,10,RED);
closegraph();
}
I have done this sucessfully. I want to know which files need to be =
included for DJGPP compiler. I have written the following program =
refering to the documentation, but it is not compiling giving an error =
c:\windows\temp\cccqjeyh(.text+0x13):temp.c: undefined reference to =
'detectgraph'
and similarly for initgraph putpixel __gr_INIT and __gr_restcecrtmode.
#include <stdio.h>
#include <libbcc.h>
int main()
{
int gd,gm;
detectgraph(&gd,&gm);
initgraph(&gd,&gm,"");
putpixel(100,100,55);
closegraph();
return 0;
}
Plese let me know what am I doing wrong.
Thanks.
Bye.
