Error when building

Hi, I am trying to use external library and arduino library in platformio everything seems to be ok! but when i try to build the code i got :


collect2.exe: error: ld returned 1 exit status
*** [.pio\build\esp32doit-devkit-v1\firmware.elf] Error 1

here is my code :


#include <stdio.h>

#include "driver/gpio.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/semphr.h"
#include <Arduino.h>

TaskHandle_t myTask1Handle = NULL;
TaskHandle_t myTask2Handle = NULL;

SemaphoreHandle_t xSemaphore = NULL;

TaskHandle_t ISR = NULL;
 #define LED_PIN_GPIO (gpio_num_t) 2
 #define BUTTON_PIN_GPIO (gpio_num_t) 0

 #define ESP_INTR_FLAG_DEFAULT 0
void IRAM_ATTR button_isr_handler(void* arg) {
  
	xSemaphoreGiveFromISR(xSemaphore, NULL);
}


 void task1(void *arg)
{


 while(1){  

   vTaskDelay(pdMS_TO_TICKS(5000));
//printf("hello from task 1 [%d]\n",xTaskGetTickCount());
//   xSemaphoreGive(xSemaphore);

 }
}

 void task2(void *arg)
{

while(1){
vTaskDelay(pdMS_TO_TICKS(3000));
printf("waiting the button!\n");
		if(xSemaphoreTake(xSemaphore,portMAX_DELAY)) {
			printf("got message! [%d] \n",xTaskGetTickCount());

		}
 }
}

void app_main()
{

  gpio_pad_select_gpio(BUTTON_PIN_GPIO);
  gpio_pad_select_gpio(LED_PIN_GPIO);
  
  // set the correct direction
  gpio_set_direction(BUTTON_PIN_GPIO, GPIO_MODE_INPUT);
    gpio_set_direction(LED_PIN_GPIO, GPIO_MODE_OUTPUT);
  
  // enable interrupt on falling (1->0) edge for button pin
  gpio_set_intr_type(BUTTON_PIN_GPIO, GPIO_INTR_NEGEDGE);

  
  //Install the driver’s GPIO ISR handler service, which allows per-pin GPIO interrupt handlers.
  // install ISR service with default configuration
  gpio_install_isr_service(ESP_INTR_FLAG_DEFAULT);
  
  // attach the interrupt service routine
  gpio_isr_handler_add(BUTTON_PIN_GPIO, button_isr_handler, NULL);


xSemaphore = xSemaphoreCreateBinary();
    xTaskCreate(task1, "task1", 4096, NULL, 10, &myTask1Handle);
   xTaskCreatePinnedToCore(task2, "task2", 4096, NULL, 10, &myTask2Handle,1);
}

here is my build error:

How can i solve this problem please?

From the missing loop and setup errors, it appears that you are using the Arduino framework, but have not defined a setup and loop functions.

Because you include Arduino.h, that pulls in a main function, which calls those two functions. You don’t need Arduino.h with FreeRTOS.

Cheers,
Norm.

Actually, I forgot to include the servo library which needs arduino.h or WPgrogram.h.
Even if i delete the Arduino.h the error persists…
here is the code :


#include <stdio.h>

#include "driver/gpio.h"
#include "freertos/FreeRTOS.h"
#include "freertos/task.h"
#include "freertos/semphr.h"
#include <SCServo.h>


TaskHandle_t myTask1Handle = NULL;
TaskHandle_t myTask2Handle = NULL;

SemaphoreHandle_t xSemaphore = NULL;

TaskHandle_t ISR = NULL;
 #define LED_PIN_GPIO (gpio_num_t) 2
 #define BUTTON_PIN_GPIO (gpio_num_t) 0

 #define ESP_INTR_FLAG_DEFAULT 0
void IRAM_ATTR button_isr_handler(void* arg) {
  
	xSemaphoreGiveFromISR(xSemaphore, NULL);
}


 void task1(void *arg)
{


 while(1){  

   vTaskDelay(pdMS_TO_TICKS(5000));
//printf("hello from task 1 [%d]\n",xTaskGetTickCount());
//   xSemaphoreGive(xSemaphore);

 }
}

 void task2(void *arg)
{

while(1){
vTaskDelay(pdMS_TO_TICKS(3000));
printf("waiting the button!\n");
		if(xSemaphoreTake(xSemaphore,portMAX_DELAY)) {
			printf("got message! [%d] \n",xTaskGetTickCount());

		}
 }
}

void app_main()
{

  gpio_pad_select_gpio(BUTTON_PIN_GPIO);
  gpio_pad_select_gpio(LED_PIN_GPIO);
  
  // set the correct direction
  gpio_set_direction(BUTTON_PIN_GPIO, GPIO_MODE_INPUT);
    gpio_set_direction(LED_PIN_GPIO, GPIO_MODE_OUTPUT);
  
  // enable interrupt on falling (1->0) edge for button pin
  gpio_set_intr_type(BUTTON_PIN_GPIO, GPIO_INTR_NEGEDGE);

  
  //Install the driver’s GPIO ISR handler service, which allows per-pin GPIO interrupt handlers.
  // install ISR service with default configuration
  gpio_install_isr_service(ESP_INTR_FLAG_DEFAULT);
  
  // attach the interrupt service routine
  gpio_isr_handler_add(BUTTON_PIN_GPIO, button_isr_handler, NULL);


xSemaphore = xSemaphoreCreateBinary();
    xTaskCreate(task1, "task1", 4096, NULL, 10, &myTask1Handle);
   xTaskCreatePinnedToCore(task2, "task2", 4096, NULL, 10, &myTask2Handle,1);
}

Here is the library file…

Why’d you create a new topic? You already posted this in exact code and error in Problem using external library, it should stay there to keep everything together.

Sorry,
they’ve blocked me because of max number of comments for a new user…

But, I need to use Arduino library with esp idf firmware together…

You might find useful information on using esp idf and Arduino, here on this thread: Framework = espidf, arduino

Cheers,
