Weird Syntax Error

[Kevin Cox]

I am compiling a simple program and am getting a weird sounding error.  I am new to sdcc but quite seasoned in C.

#define __16f690
#include <pic16f690.h>
#include <stdint.h>
void main ( void )
{
    TRISB = 0xFF;
    unsigned char c = 1;
}

Gives:

$ sdcc -mpic14 -p16f690 --use-non-free main.c
main.c:10: syntax error: token -> 'unsigned' ; column 9

But if I comment our the first line:

#define __16f690
#include <pic16f690.h>
#include <stdint.h>
void main ( void )
{
//  TRISB = 0xFF;
    unsigned char c = 1;
}

I get:

$ sdcc -mpic14 -p16f690 --use-non-free main.c
message: using default linker script "/usr/share/gputils/lkr/16f690.lkr"

I was hoping someone a bit more seasoned could help me out.

And for refrence:

Oh, and I realized stdint.h wasn't needed.  I get the same error when it is removed.

#define __16f690
#include <pic16f690.h>
void main ( void )
{
    TRISB = 0xFF;
    unsigned char c = 1;
}

The same thing happens if I replace the assignment with a function call.

#define __16f690
#include <pic16f690.h>
void func ( void )
{
    return;
}
void main ( void )
{
    func();
    int c;
}

You are not seasoned enough it seems. Placing variable declarations after instructions is only allowed in C99 and not in C89. And furthermore SDCC does not support it in any mode as described in the manual under ANSI compliance.

Thank you,  I thought of this as I was going to bed.  its been forever since I used c89 complaint c.  Thanks once again and have a great day.
