ElegantOTA.cpp:73:71: error: 'FS_end' was not declared in this scope;

[VaAndCob]

I installed the library both on PC (windows) and Apple Mac(intel5) both machines are Arduino 2.2.1

• Arduino on PC (Windows 10) compiled and ran fine.

• Arduino on MacBook throws error messages: /Volumes/Arduino/Sketch/libraries/ElegantOTA/src/ElegantOTA.cpp: In lambda function: /Volumes/Arduino/Sketch/libraries/ElegantOTA/src/ElegantOTA.cpp:73:71: error: 'FS_end' was not declared in this scope; did you mean 'va_end'? 73 | uint32_t update_size = mode == OTA_MODE_FILESYSTEM ?

((size_t)FS_end - (size_t)FS_start) : ((ESP.getFreeSketchSpace() - 0x1000) & 0xFFFFF000); | ^~~~ | va_start

  I guess it's about FS.h?

Check if both PC and macbook have the same board version installed?

it's exactly the same ESP8266 module, (Generic ESP8266) but Arduino IDE was unable to compile due to error messages above. (both PC and Macbook use library and sketch code from the same resource (dropbox) . I wonder why PC was successful compile but not macbook. Are "FS_end" and "FS_start" not declare error come from different "FS.h" ?

[ayushsharma82]

FS_end and FS_start are defined in FS.h but my speculation is that platform/board version is different. Check it in Board Manager > ESP8266

it's the latest version. ESP8266 Board(3.0.2). No update both machine lately.

[ayushsharma82]

@VaAndCob It's an issue in ESP8266 Board 3.0.2 version. I compiled the example successfully with 3.1.2 (latest) on my MacBook (M1)

[VaAndCob]

I manually copied and replace arduino core library file FS.h and FS.cpp from github ESP8266 arduino core but it gave the same error messages.

Consider updating to 3.1.2 release of ESP8266 board. It does not compile with 3.0.2

oh ok, I must manually update to 3.1.2 Thank you a lot.

@VaAndCob As this is a new release, I will need a small feedback. Once you have tried ElegantOTA, let me know if it updated your ESP8266 without any hiccups or not.

[ElegantOTA] OTA Mode: Firmware [ElegantOTA] MD5: 441018525208457705bf09a8ee3c1093 sleep disable [ElegantOTA] Rebooting... station: ee:b1:48:1f:20:b8 leave, AID = 1

I confirm it works like a charm.

[ayushsharma82]

Awesome! Thanks for the feedback.
