Compiler Error while Update from 2.0.3 to 2.2.9

[JoergTiedemann]

HI
i'm currently using Version 2.0.3 and all worked fine. Now i want to update to Version 2.2.9 but i get a compiler error

I seems there is a missing definition of FIREBASE_SSE_TIMEOUT_MS
in my platformio.ini i have the following definitions

build_flags = 
	-D ENABLE_DATABASE
	-D ENABLE_MESSAGING
	-D ENABLE_SERVICE_AUTH

in in my code i have the includes

#include <WiFi.h>
#include <FirebaseClient.h>
#include <ESP_SSLClient.h>
#include "ExampleFunctions.h" // Provides the functions used in the examples.

so what is going wrong ?
Every help was great

Thanks for reporting this issue. The library is now updated to v2.2.10 that fixes this issue.
Please wait for PlatformIO registry update.

[JoergTiedemann]

Thank you very much for your support
What did you mean with platformio registry update ?

[mobizt]

At the. time I replied your message, the new version is published to platformio library registry system and it needs time for the update to be available to user.

Now you can update it.

[JoergTiedemann]

ok thanks for your support again
compiler error is now fixed, but ich get an linker error now, sorry

I got a multiple definition of firebase_ns::JWTClass::sendErrCB(.. error at linking time
my sign in looks like

   ServiceAuth sa_auth(FIREBASE_CLIENT_EMAIL, FIREBASE_PROJECT_ID, pvkey, 3000 /* expire period in seconds (<= 3600) */);
  
      initializeApp(aClient, app, getAuth(sa_auth), 120 * 1000, printResult);
      //authHandler(&m_bFirebaseTokenReady);
      // Binding the FirebaseApp for authentication handler.
      app.getApp<RealtimeDatabase>(Database);
      // Binding the FirebaseApp for authentication handler.
      app.getApp<Messaging>(messaging);
      Database.url(DATABASE_URL);

It seems that if a define ENABLE_SERVICE_AUTH
internally defines also ENABLE_JWT
coud this caught the multiple definition of firebase_ns::JWTClass::sendErrCB(.. error at linking time
or what could be the reason ?

Thanks for your help in forward

You should clean your project or delete .pio/libdeps folder.

I have tested with the following platformio.ini and code. Everything works fine

Hello
I understand this and your example works well also in my environment
The problem is
I've several modules that use functions from FirebaseClient.h so I've to include FirebaseClient.h in more then one of my cpp files
If i do this, I got the linker error
If I use ENABLE_SERVICE_AUTH then also ENABLE_JWT is defined
In firebaseClient.h i see the following code

#if defined(ENABLE_JWT)
#include "./core/JWT/JWT.h"
#include "./core/JWT/JWT.cpp"
#endif
#include "./core/FirebaseApp.h"
#include "./core/AsyncClient/AsyncClient.h"

This means, the implementation of JWT will be included by #include ./core/JWT/JWT.cpp in the firebaseClient Header file
Is this correct ?
If I include firebaseClient.h in more the one cpp file I got the multiple definition of firebase_ns::JWTClass::sendErrCB(.. error at linking time

In Version 2.0.3 I can include firebaseClient.h in several cpp modules but not in Version 2.2.10
How can I solve this problem to use FirebaseClient functions in several different cpp modules, if I am not able to include firebaseClient.h in each required module ?
This is really a big breaking change between 2.0.3 and 2.2.10
Thanks for any help in advance

[JoergTiedemann]

no Idon't use pioarduino,
I use legacy platformio

platform = espressif32
board = esp32dev
framework = arduino

I use Adruino-Espressif-Framework Version 2.0.17

[mobizt]

That platformio/espressif is end of life, no more supports from PlatformIO dev team and it stays on Arduino-ESP32 core v2.x (ESP-IDF 4.x) and compile using gnu++11.

Actually, I'm not intend to support that deprecated platform but I will fix this compatibility issue soon.

[JoergTiedemann]

ok thank you very very much

[mobizt]

I already update the library to v2.2.12, please try.

[JoergTiedemann]

Now it works,
No compiler and no linker errors with multiple include of firebaseclient.h in different cpp files
Thank you very much for your support
