Help needed: clangd in VSCode with ESP-IDF reports printf function not found error

[1403847775@qq.com]

The following is the complete source code, which compiles successfully but triggers errors in clangd.
#include "driver/gpio.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"

#define OUT_GPIO GPIO_NUM_15
#define OUT_MASK (1ULL<<OUT_GPIO)

void app_main(void)
{
gpio_config_t io_conf={OUT_MASK,GPIO_MODE_OUTPUT,GPIO_PULLUP_DISABLE,GPIO_PULLDOWN_DISABLE,GPIO_INTR_DISABLE};
gpio_config(&io_conf);
while(true)
{
gpio_set_level(OUT_GPIO, 1);
vTaskDelay(1000/portTICK_PERIOD_MS);
printf("输出一\n");
gpio_set_level(OUT_GPIO, 0);
vTaskDelay(1000/portTICK_PERIOD_MS);
printf("输出零\n");
}
}

Try adding #include <stdio.h>.

Try adding #include <stdio.h>.

I've already attempted this, yet clangd persists in reporting 'printf function not found'.
