Description: Compiler error after the last update.

The previouos update was done two weeks ago and everything was working fine. Few minutes ago I downloaded and installed the last update (idf update included) and now I'm not able to compile my projects due an undefined refererence in the precompiled library. This is the message produced by the linker:

Is someone experiencing this issue ?

make clean?

[dsptech]

Fully cleaned before recompiling (any object files folder and related was also manually deleted and also all temporary files).

For testing purpose, I also rolled back to the commit 7abd586 and my projects now are succesfully compiling again.

[dsptech]

Update:
Now I applied only the update: a59eafb and the issue now is on again.
I also see (from idf sources) that the missing reference error came from the same binary library where the symbols should be declared (libesp32.a) , so, it's very strange.

I also updated the /arduino-esp32 libs and I get the same errors at compiling:

Hi,
It seems to me that the smartconfig source code is not included in the precompiled library. The missing symbols are declared here.

[william-ferguson-au]

This is a problem. Master is currently broken because of this.

[dsptech]

I forgot to link the commit :
#1539

[me-no-dev]

ok will look into the libs today and see where smartconfig went.

[me-no-dev]

I just checked the examples and we do have a smartconfig example in the repo. If it's missing as you say, how did that example compile? Can you give some minimal example sketch that triggers this issue?

[dsptech]

Hi,
I'm not using smartconfig at all. I only inspected the sourcecode and I seen that the missed functions sc_ack_send and sc_ack_send_stop are declared in smartconfig_ack.h and implemented in smartconfig_ack.c.

I'm not in my developing machine now (and I'm unable to perform checks today) but, regarding networking, my project is using only : WiFi.mode(WIFI_STA), WiFi.scanNetworks, WiFi.disconnect, WiFi.begin, esp_wifi_set_country and the directly the lwIP netconn APIs (for UDP packets). Any reconnect or autoconnect feature is disabled.

No other networking APIs are used (could this cause the issue ?).

I rolled back to the previous commit again, so, creating an example sketch will require a bit of time. I hope to post it tomorrow in the evening.

.... I will try also to compile the smartconfig example (just in case... )

Thank you.

Hi @me-no-dev ,
I can confirm the missing smartconfig, but it is not a library issue. It is a my IDE issue.
I performed several checks and I discovered that my IDE (ecplise based - sloeber) does not recognize the changes of the include list in platform.txt (even forcing a refresh and cleaning any compiler created files too)
So, the new directory smartconfig_ack was not handled in compile and the linker error is produced.

It seems that the only way to force a new platform.txt scan is to choose another board family (example: Arduino Nano) and, after that, choose again the proper ESP32 board.
Other users that are using Ardino IDE have posted similar messages, so, I suspect that the problem is the same.

... I'm sorry to have bothered you for this non-issue.
