Managed to compile a sample code below with sdcc, but the xdata
definition can not be found from header files (except from testfwk.h).
What would be the correct way to introduce the heap ?
Thank you again,
-Mika
Code I have been compiling:
#include <pic16/pic18f4550.h>
#include <stdio.h>
#include <math.h>
#include <malloc.h>
#include <stdlib.h>
#include <sdcc-lib.h>
// xdata char heap[256]; This gives error of missing xdata
data char heap[256];
// data char heap[512]; This gives linker error, do not know why
int
main()
{
float f1, f2;
char *s1;
s1 = (char *) malloc (100);
f1 = 3.14;
f2 = sqrtf(f1);
sprintf(s1, "Float s1=%f and s2=%f", f1,f2);
return 0;
}
