error #150: variable "g_pcHex" has already been initialized

Hello

I made a new proyect in CCS using UART with the launchpad tm4c123xl, but when I compile, I get this error. I only copy and paste the hello.c code example in the new project.

line 134: error #150: variable "g_pcHex" has already been initialized

and this is the code

#include <stdint.h>
#include <stdbool.h>
#include "utils/ustdlib.c"
#include "utils/ustdlib.h"
#include "inc/hw_memmap.h"
#include "inc/hw_types.h"

    SysCtlPeripheralEnable(SYSCTL_PERIPH_UART0);

    GPIOPinConfigure(GPIO_PA1_U0TX);
    GPIOPinTypeUART(GPIO_PORTA_BASE, GPIO_PIN_0 | GPIO_PIN_1);

    UARTClockSourceSet(UART0_BASE, UART_CLOCK_PIOSC);

    UARTStdioConfig(0, 115200, 16000000);
}

int main(){

	FPULazyStackingEnable();
	SysCtlClockSet(SYSCTL_SYSDIV_4 | SYSCTL_USE_PLL | SYSCTL_XTAL_16MHZ | SYSCTL_OSC_MAIN);
	SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
	GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_2);
	ConfigureUART();

	while(1)
	{

		UARTprintf("Hello, world!\n");

		GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, GPIO_PIN_2);
		SysCtlDelay(SysCtlClockGet() / 10 / 3);
		GPIOPinWrite(GPIO_PORTF_BASE, GPIO_PIN_2, 0);
		SysCtlDelay(SysCtlClockGet() / 10 / 3);

	}
}

Can you help me to solve this issue?

Regards!
