ERROR #10234-D unresolved symbols remain and ERROR #10010 error encountered during linking

Can anybody tell how is the following error regarding linking of files and unresolved symbols solved; since it is a common error I encounter while building many of my codes.

In this program I have included the "utils/uartstdio.h" where the definitions for the so called unresolved symbols is given but still the error persists.

Here's the code I used from the examples;

#include "inc/hw_memmap.h"
#include "inc/hw_types.h"
#include "driverlib/adc.h"
#include "driverlib/gpio.h"
#include "driverlib/sysctl.h"
#include "driverlib/uart.h"
#include "utils/uartstdio.h"

#define GPIO_PA0_U0RX 0x00000001
#define GPIO_PA1_U0TX 0x00000401

void
InitConsole(void)
{
//
// Enable GPIO port A which is used for UART0 pins.

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA);

GPIOPinConfigure(GPIO_PA0_U0RX);
GPIOPinConfigure(GPIO_PA1_U0TX);

//
// Select the alternate (UART) function for these pins.

GPIOPinTypeUART(GPIO_PORTA_BASE, GPIO_PIN_0 | GPIO_PIN_1);

//
// Initialize the UART for console I/O.
//
UARTStdioInit(0);
}

int
main(void)
{

unsigned long ulADC0_Value[1];

SysCtlClockSet(SYSCTL_SYSDIV_10 | SYSCTL_USE_PLL | SYSCTL_OSC_MAIN |
SYSCTL_XTAL_16MHZ);

InitConsole();

//
// Display the setup on the console.
//
UARTprintf("ADC ->\n");
UARTprintf(" Type: Single Ended\n");
UARTprintf(" Samples: One\n");
UARTprintf(" Update Rate: 250ms\n");
UARTprintf(" Input Pin: AIN0/PE7\n\n");

SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);

SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOE);

GPIOPinTypeADC(GPIO_PORTE_BASE, GPIO_PIN_3);

//
ADCSequenceConfigure(ADC0_BASE, 3, ADC_TRIGGER_PROCESSOR, 0);

ADCSequenceStepConfigure(ADC0_BASE, 3, 0, ADC_CTL_CH0 | ADC_CTL_IE |
ADC_CTL_END);

//
// Since sample sequence 3 is now configured, it must be enabled.
//
ADCSequenceEnable(ADC0_BASE, 3);

//
// Clear the interrupt status flag. This is done to make sure the
// interrupt flag is cleared before we sample.
//
ADCIntClear(ADC0_BASE, 3);

//
// Sample AIN0 forever. Display the value on the console.
//
while(1)
{
//
// Trigger the ADC conversion.
//
ADCProcessorTrigger(ADC0_BASE, 3);

//
// Wait for conversion to be completed.
//
while(!ADCIntStatus(ADC0_BASE, 3, false))
{
}

//
// Clear the ADC interrupt flag.
//
ADCIntClear(ADC0_BASE, 3);

//
// Read ADC Value.
//
ADCSequenceDataGet(ADC0_BASE, 3, ulADC0_Value);

//
// Display the AIN0 (PE7) digital value on the console.
//
UARTprintf("AIN0 = %4d\r", ulADC0_Value[0]);

// Delay
// 250ms arbitrarily.
//
SysCtlDelay(SysCtlClockGet() / 12);
}
}
