I’m a beginner and trying to add a library from GitHub to my project.
I have added the following code in my platformio.ini file:
lib_deps =
; nrf24L01
tmrh20/RF24@^1.3.11
; E22
https://github.com/wanfp97/EByte_LoRa_E22_Series_Library
the library for the nrf24L01 works well but after I add in the E22 library using the GitHub link and rebuild, the following error occurs:
If I’m not mistaken, the SoftwareSerial.h is an inbuilt library for the Arduino framework. Am I adding the GitHub library wrongly? If yes, please guide me on how to add the library correctly.
Ps: I can’t find the library by searching it within the Platformio and thus I’m adding it using the GitHub link.
Since the library inclusion is guarded by a macro
PlatformIO’s library dependency finder (LDF) needs to be set to a more aggressive mode to recognize the dependency. As per docs, try adding
lib_ldf_mode = chain+
to the platformio.ini and retry compilation.
Did you mean like this?
but the problem still remains

I cannot reproduce the issue when using the source code
#include <Arduino.h>
#include <RF24.h>
#include <LoRa_E22.h>
void setup() {
}
void loop() {
}
and platformio.ini
[env:uno]
platform = atmelavr
board = uno
framework = arduino
lib_deps =
; nrf24L01
tmrh20/RF24@^1.3.11
; E22
https://github.com/wanfp97/EByte_LoRa_E22_Series_Library
lib_ldf_mode = chain+
Make sure to at least include the library’s header in your code.
