new esp-idf-project with the use of components; #include driver/gpio.h: No such file or directory

[mmueller]

Hi together,

first of all, I don't have much experience in programming the ESP32 a the moment.
So the answer for my problem could be simple.

Currently, I have ESP-IDF v5.2 installed on my ubuntu host under the directory ~esp/esp-idf/.
Next to this directory I have created a simple esp-blinki-project with the command `idf.py create-project bliki`.
The main `blinki.c` includes among others `#include driver/gpio.h`.
When I use the comman `idf.py build` and `idf.py flash`, everithing works fine.
A LED, which is connected to the ESP32-Board, goes on and off... .

Now the Problem:
Next to my simple esp-blinki-project I created a new project to get experience with the use of own written components.
I used the the commands:
- idf.py create-project blinki-03
- Created the sub directory components for my component cledlight.
- mkdir components
- cd components
- idf.py create-component cledlight

The file cledlight.c includes among other includes `#include driver/gpio.h`.
When I try to build the project with the comman `idf.py build` I get the error message `fatal error: driver/gpio.h: No such file or directory`.

My attempts to include the esp-idf components (gpio.h ...) in the CMake-Files have so far been unsuccessful.
(I hope this post will be readable )
I would be very greatful if someone could help me.



Here you can see the code of the component cledlight:
[1] cledlight.c

Code: Untitled.c Select all

#include <stdio.h>

#include "cledlight.h"



#include "freertos/FreeRTOS.h"

#include "freertos/task.h"



#include "driver/gpio.h"



void config_blink(void){

    gpio_set_direction(GPIO_NUM_5, GPIO_MODE_DEF_OUTPUT);

}



void blink_on(void){

    gpio_set_level(GPIO_NUM_5, 1);

    vTaskDelay(2000 / portTICK_PERIOD_MS);

    gpio_set_level(GPIO_NUM_5, 0);

    vTaskDelay(2000 / portTICK_PERIOD_MS);

}

[2] include/cledlight.h

Code: Untitled.c Select all

void config_blink(void);

void blink_on(void);

[3]CMakeLists.txt

Code: Untitled.txt Select all

idf_component_register(SRCS "cledlight.c"

                    INCLUDE_DIRS "include")

Here you can see the main:
[4] blinki-03.c

Code: Untitled.c Select all

#include <stdio.h>



#include "cledlight.h"



void app_main(void)

{

    config_blink();



    while(1){

        blink_on();

    }



}

[5] CmakeList.txt

Code: Untitled.txt Select all

idf_component_register(SRCS "blinki-03.c"

                    INCLUDE_DIRS ".")

Here you can see the "main"-CMakeLists.txt of the project.
[6] CMakeLists.txt

Code: Untitled.txt Select all

# For more information about build system see

# https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html

# The following five lines of boilerplate have to be in your project's

# CMakeLists in this exact order for cmake to work correctly

You need to add a 'REQUIRES driver' to the idf_component_register of your component.

It works, i'm so happy
I tried so many things to solve this problem.
Many thanks for this hint.

thanks!

I have the same problem and can't solve it. Can you share your CMakeLists.txt ?
