Hi All,
I'm a newbie for sdcc.
A few days ago, I was in use of SDCC, ran into a problem.
Program (bee.c) is very simple, as follows:
#include<reg51.h>
#include<stdio.h>
sbit P10=P1^0;
sbit P17=P1^7;
int main(void)
{
unsigned char j;
unsigned int i;
while(1){
P17=1;
while(P17==0)
{
for(i=1;i<=500;i++)
{
P10=~P10;
for(j=0;j<=50;j++);
}
for(i=1;i<=250;i++)
{
P10=~P10;
for(j=0;j<=100;j++);
}
}
}
return 0;
}
My compiler option was sdcc -mmcs51 bee.c
But SDCC gave me such an error message : bee.c:3:error 2:Initializer
element is not constant
bee.c:4:error 2:Initializer element is not constant
It means the expression: sbit P10=P1^0 was wrong.
I used keil C running the program,it compiled successfully,no
errors,no warnings.
Later,I got other programs to compile with SDCC.I found that where
there is sbit instructions, there is error 2:Initializer element is not
constant
But keil C still can compile successfully.
So,what is the solutions?To modify the program?How to do it? Or modify
the sdcc?
thanks！
Donald
