Add external library

[roysG]

Hi,
I want to work with the library: "https://github.com/vshymanskyy/TinyGSM"

I tried to put this package in the esp32-arduino-lib-builder/arduino/components/arduino/libraries.
But there is no any effected.

What do i miss?

you should look into the esp-idf build system. You need to add the lib as extra component and include CMakeLists.txt inside that has the proper lines to enable building that code.

First thing, thanks for your help. Can you send me some example or dirct me to link that explain it further? This is very important information, foe enyone that want to learn gow to work with your library. Thank you.

@roysG
You could do something like this. For the Adafruit_BusIO library for example.

Clone it under your idf project's components.
Just add CMakeLists.txt

idf_component_register(
    SRC_DIRS "."
    INCLUDE_DIRS "."
    REQUIRES arduino
)

and component.mk

COMPONENT_ADD_INCLUDEDIRS = .

Running this library example

#include "Arduino.h"
#include "Adafruit_I2CDevice.h"

Adafruit_I2CDevice i2c_dev = Adafruit_I2CDevice(0x10);

void setup() {
  while (!Serial) { delay(10); }
  Serial.begin(115200);
  Serial.println("I2C address detection test");

  if (!i2c_dev.begin()) {
    Serial.print("Did not find device at 0x");
    Serial.println(i2c_dev.address(), HEX);
    while (1);
  }
  Serial.print("Device found on address 0x");
  Serial.println(i2c_dev.address(), HEX);
}

void loop() {
  
}

extern "C" void app_main()
{
    initArduino();
    pinMode(4, OUTPUT);
    digitalWrite(4, HIGH);
    // Do your own thing
}

You may need to run idf.py menuconfig again after adding a new component

The most library i succeeded to add successfully with the "CMakeLists.txt",
But there is a specific library that i still get errors in build.

This library is: https://github.com/OPEnSLab-OSU/SSLClient

Maybe someone know what are the required steps?
