WebAuthentication.cpp:73: undefined reference to `mbedtls_md5_starts'

[41linea45]

Hi,
I am using Visual Studio code and added last library to my project.
platform.ini:
env:esp32dev] platform = espressif32 board = esp32dev framework = arduino lib_deps = me-no-dev/ESP Async WebServer@^1.2.3 me-no-dev/AsyncTCP@^1.1.1 ayushsharma82/AsyncElegantOTA@^2.2.6
It gives error:

c:/users/delphi/.platformio/packages/toolchain-xtensa-esp32@8.4.0+2021r2-patch3/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: .pio\build\esp32dev\lib299\libESP Async WebServer.a(WebAuthentication.cpp.o):(.literal._ZL6getMD5PhtPc+0x4): undefined reference to mbedtls_md5_starts' c:/users/delphi/.platformio/packages/toolchain-xtensa-esp32@8.4.0+2021r2-patch3/bin/../lib/gcc/xtensa-esp32-elf/8.4.0/../../../../xtensa-esp32-elf/bin/ld.exe: .pio\build\esp32dev\lib299\libESP Async WebServer.a(WebAuthentication.cpp.o): in function getMD5(unsigned char*, unsigned short, char*)':
D:\Yazilim\Off_Road_2\ESP32\Inclinometer2/.pio/libdeps/esp32dev/ESP Async WebServer/src/WebAuthentication.cpp:73: undefined reference to `mbedtls_md5_starts'

How can i solve this problem? I used just sample code.

I had the same issue, waiting for the solution.

update: I had check the esp32 framework tool, and realized that the md5.h file had a small changing, the mbedtls_md5_starts() was removed. I think the radical solution is on the next update on the AsyncWebServer library.

update: the WebServer file was use new function mbedtls_md5_starts_ret() instead mbedtls_md5_starts().

I just ran into this as well. I forced an older version of the expressif framework in platform.io for now:

  framework = arduino
  platform = espressif32@3.5.0
  board = esp32doit-devkit-v1

is there a way to force older version on Arduino IDE? currently my Platform IO is not running in VS Code(separate problem) so i can barely even try

your compiler crash out .Try reinstall Platformio and delete library folder in .pio/libdeps/ and than uninstall platformio, find this folder espressif32@3.5.0 and also delete ,also dont install ArduinoIDE in VScode when you running Platformio. but first you should try clean button at VScode or clean all (this function clean also librarys so when you use some custom better make copy of .pio/libdeps/ ). I got similar issue with esp8266 .

super annoying issue, I used the workaround from #1085 to be able to compile my project. Please fix

I think there may be a versioning issue, v1.2.3 was released 3 years ago
https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/library.properties 2 Oct 2019
platformio get this version
https://registry.platformio.org/libraries/me-no-dev/ESP%20Async%20WebServer/versions
then after that at 26 Jul 2021 have a new file without new version
https://github.com/me-no-dev/ESPAsyncWebServer/blob/master/src/WebAuthentication.cpp

My bet is, that platformio will only update their files if you release a new version like 1.2.4

https://docs.platformio.org/en/latest/librarymanager/creating.html
"Publishing
You can publish a library to the PlatformIO Registry using pio pkg publish command. Every time when you modify a source code of a library you will need to increment the “version” field in library.json manifest and re-publish again."

Same issue, won´t write to esp until you switch to expressiv 3.5.0; If you use expressiv 3.5.0, then everything should be fine...

[DanteNahuel]

PlatformIO still gives problems because the version in the json shows as 1.2.3 so Platform doesn't try to update the files.

[JellevanKraaij]

Any updates on when this is fixed?

Hello again
Thank you very much for replies. I apoligize for late feedback.
I solved problem in platformIO like that:

lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git

[MartinVerges]

That's not solving, that's just a workaround. We need a simple version upgrade and a clean update of the registry files. This can only be done by the maintainer and it takes as little as a minute to solve the whole problem.
