我是按照这个帖子按部就班的创建一个STM32F103C8T6的项目工程

最后一步编译的时候出现了这堆错误

```c
#include <rtthread.h>
#include <rtdevice.h>

#define DBG_TAG "main"
#define DBG_LVL DBG_LOG
#include <rtdbg.h>

#define OUT16   4

int main(void)
{
    int count = 1;

rt_pin_mode(OUT16, PIN_MODE_OUTPUT);
    while (count++)
    {
        LOG_D("System CLock information");
        LOG_D("SYSCLK_Frequency = %d", HAL_RCC_GetSysClockFreq());
        LOG_D("HCLK_Frequency   = %d", HAL_RCC_GetHCLKFreq());
        LOG_D("PCLK1_Frequency  = %d", HAL_RCC_GetPCLK1Freq());
        LOG_D("PCLK2_Frequency  = %d", HAL_RCC_GetPCLK2Freq());

rt_pin_write(OUT16, PIN_HIGH);
        LOG_D("Hello RT-Thread! OUT16 HIGH");
        rt_thread_mdelay(1000);
        rt_pin_write(OUT16, PIN_LOW);
        LOG_D("Hello RT-Thread! OUT16 LOW");
        rt_thread_mdelay(1000);
    }

return RT_EOK;
}

```
本人RTOS小白，对于这问题研究了好久也无从下手。希望前辈们能帮忙解决一下困境
