Error on compiling c file on MPLAB X ide

Question

I get following errors when trying compile using MPLAB X on Windows..

---

newmain.c:40:9: error: unknown configuration setting: 'JTAGEN'

newmain.c:61:2: error: 'LATA' undeclared (first use in this function)

newmain.c:62:2: error: 'TRISA' undeclared (first use in this function)

newmain.c:61:2: error: 'LATA' undeclared (first use in this function)

I tried this on 2 different machines (on Windows 8.1 and Vista), but they all gave me same error.

It seemed like that xc.h file is already included to project since I can open that file. And also I googled for this problem but there wasn't a solution for this.

Thank you very much if you can give me a possible way to solve this.

I also attached photo describing project properties ​for this project.

Following is full description of error :

And source is

#include <xc.h>

#pragma config FWDTEN = OFF, JTAGEN = OFF

void delay(void);

unsigned int ctr = 0;
unsigned int delayVal = 2048;

int main(void)
{
    LATA = 0;
    TRISA = 0xFF00;

    while(1)
    {
        LATA = 0x0055;
        delay();

        LATA = 0x00AA;
        delay();

        ctr++;
    }
}

void delay(void)
{
    unsigned int i,j;

    for (i = 0; i < delayVal; i++)
    {
        for (j = 0; j < 20; j++);
    }
}

Answer 1

The errors you receive indicate that the compiler does not see any libraries to reference those registers to. It treats them as regular variables instead.

You should include the specific header file for the processor you are using and also check to see what registers are structured in there to make more sense of your problem.
