I need to compile and link in floating point emulation.
My compiler is visual c++ 6.0.
I checked all of the compiler and link options in the IDE but could not find anything. The following code is compiled and it is run on a 386 embedded system. This 386 does not have a floating point processor on it, so my
sin function and circle function do not work.
Any help would be greatly appreciated.

CODE
--------------------------------------------------------------------------------------
#include <gdisp.h> /* LCD prototypes */
#include <gsimintf.h>
#include <gkeycode.h>
#include <stdio.h>
#include <math.h>
#include "gcolorcv.h"
#define PIVALUE 3.141592
int main(void)
{
float f;
GXT x; GYT y;
int i;
ginit();
gselvp(0);
gsetcvp(9,0,17,8);
gputs("\n");
gputs("line 1\n");
gputs("line 2\n");
gputs("line 3\n");
gcrectangle(0,0,ggetvpw()-1, ggetvph()-1,G_BLACK);
gcrectangle(2,2,ggetvpw()-3, ggetvph()-3,G_BLACK);
gselvp(1);
gsetcvp(0,0,8,8);
gcrectangle(0,0,ggetvpw()-1, ggetvph()-1,G_BLACK);
gcrectangle(2,2,ggetvpw()-3, ggetvph()-3,G_BLACK);
gmoveto(3,ggetvph()/2);
glineto(ggetvpw(),ggetvph()/2);
gmoveto(3,ggetvph()/2);
for (x = 3; x < ggetvpw()-3; x++)
{
f = PIVALUE*2.0;
f *=x;
f /= ggetvpw();
y = (ggetvph())/2-(GYT)(sin(f) * (ggetvph())/2);
glineto(x,y);
}
gselvp(2);
gsetcvp(0,9,8,20);
gcrectangle(0,0,ggetvpw()-1, ggetvph()-1,G_BLACK);
gcrectangle(2,2,ggetvpw()-3, ggetvph()-3,G_BLACK);
for (i = 1; i < 4; i++)
gcircle(20,20, 5*i,0);
gselvp(3);
gsetcvp(10,10,17,20);
gputs("How you doing!!");
return 0;
}
