Arduino: ESPAsyncWebServer

[kiralikbeyin]

I uploaded same sketch maybe 10 times now it is giving exception again...

@igrr Can it be a core problem with time lib?

Did you include <time.h> in WebHandlers.cpp?
Also please describe your environment: which versions of the ESP8266 Arduino core and ESPAsyncWebServer are you using, how you are building the code (Arduino IDE or other build system), and the minimal sketch to reproduce the issue. Thank you.

Tried with 1.6.8 and 1.6.9 not other platform
esp 2.3 stable and staging
Nodemcu v3 LoLin

i will upload the sketch now...

Just to repeat, please describe your environment: which versions of the ESP8266 Arduino core and ESPAsyncWebServer are you using, how you are building the code (Arduino IDE or other build system), and the minimal sketch to reproduce the issue. Thank you.

[kiralikbeyin]

I reinstall esp8266 2.3 and no problem now.

I am not sure if it makes trouble again.

Thank you Ivan :)

[igrr]

No problem! I'm Ivan by the way :)

Nightmare again

Arduino: 1.6.8 (Mac OS X), Board: "NodeMCU 1.0 (ESP-12E Module), 80 MHz, 115200, 4M (3M SPIFFS)"

Error compiling for board NodeMCU 1.0 (ESP-12E Module).

@igrr updated https://github.com/kiralikbeyin/convert-to-async

[kiralikbeyin]

/Library/Arduino15/packages/esp8266/tools/xtensa-lx106-elf-gcc/1.20.0-26-gb404fb9-2/xtensa-lx106-elf/include
Make a copy of time.h and name it to "_time.h"

replace in WebHandlerImpl.h #include to #include <_time.h>

I will give info when i get problem again...

[igrr]

Do you have some other file called "Time.h" somewhere in your include paths?

[kiralikbeyin]

Orginal arduino lib https://github.com/PaulStoffregen/Time and esp8266 core time lib nothing more...
I didn't get any error with time lib before.

But my duplicate time.h _time.h files solved it for now.

Thanks for your attention.

[bhcuong2008]

I've just faced error undefined reference to strftime. Arduino 1.6.10, ESP stable 2.3.0, on ESP-12.

In path "AppDataLocalArduino15packagesesp8266toolsxtensa-lx106-elf-gcc1.20.0-26-gb404fb9-2xtensa-lx106-elfinclude", I see file time.h, including function strftime.

Please help me.

Thank you.

I have this problem also, on windows only, not linux. I solved it by deleting the "Time.h" from the Time library (https://github.com/PaulStoffregen/Time), and using TimeLib.h only in my code.
