RCC_AHB1PeriphClockCmd could not be resolved

Hello again,

Im decided to switch my first project stm32 from the HAL driver library to the SPL. I was able to get a blinky program working using the STCubeMX software and Kei1 with the HAL drives, but i want to write the code om my own in Eclipse. Everything seems to be working, but i can't figure out why i cannot resolve RCC_AHB1PeriphClockCmd().

I believe i have included all the necessary files. I went into  stm32f10x_conf.h and uncommented _gpio.h, _rcc.h, and also uncommitted #define STM32F10X_MD and #define USE_STDPERIPH_DRIVER in  stm32f10x.h but im still getting errors.  I also tried to include _rcc.h directly into main as you can see in my code with no luck. Any suggestions?

#include <stm32f10x.h>
#include <stm32f10x_conf.h>
#include <stdio.h>
#include <stdlib.h>
#include "diag/Trace.h"
#include "stm32f1-stdperiph\stm32f10x_rcc.h"
#define GPIO_PORT       GPIOC
#define GPIO_PIN        GPIO_PIN_13
void GPIO_Init(void);
GPIO_InitTypeDef GPIO_InitStruct;
int main(/*int argc, char* argv[]*/)
  // At this stage the system clock should have already been configured
  // at high speed.
  // Infinite loop
  while (1)
       // Add your code here.
  return 0;
void GPIO_Init(void) {
    RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOC, ENABLE);
