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:

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 = [email protected]
  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

[IronBamBam1990]

your compiler crash out .Try reinstall Platformio and delete library folder in .pio/libdeps/ and than uninstall platformio, find this folder [email protected] 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 .

[MartinVerges]

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

[82andre]

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?

[41linea45]

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.

Can someone update the library / registry to fix other projects using the old style lib_deps = ESP Async WebServer? Thanks!

Following this logic by @82andre (thanks) I was able to solve the problem. By downloading the library directly (Code -> Download ZIP) and copying it to the libraries folder of my PlatformIO project (Project/lib/ESPAsyncWebServer).

PlatformIO.ini entry

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

This solved it for me (rather then the usual me-no-dev/ESP Async WebServer@^1.2.3 entry) but it means this still has not been "fixed" natively. Still is version 1.2.3.

[me-chiel]

Thanks for the quick fix:

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

this works for me, took me a while to figure that out....

[kiliw]

Has there been an update? Don't think so, right? I came across the issue since my GitHub action failed with this error. If I build the project locally with platform io everything works fine. I used the approach mentioned above and it fixed the CI build problem

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

Would love to use the standard way again and not this workaround.

Thanks

[sanjayraojjn]

replacing //platfromio.ini lib_deps = ESP Async WebServer

with

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

worked. Is platformIO repo using an older version of the server?

[h0l0gram]

@me-no-dev Please see https://github.com/me-no-dev/ESPAsyncWebServer/issues/1147#issuecomment-1120415957. It seems to be a quickfix! Until you release a version >1.2.3 with platformio, all will get this ugly error.

[Jefferson-Lopes]

I'm still getting this same error

[RalphBacon]

You can remove this error in PlatformIO by editing

.pio\libdeps\esp32dev\ESP Async WebServer\src\WebAuthentication.cpp

and remove (comment out) the call to mbedtls_md5_starts(&_ctx); (line 74, approx).

Or just get the library another way like this:

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

which seems to force the download of the correct version of the library.

[mjechow]

better use mbedtls_md5_starts_ret() instead of commenting out a deprecated method.

[RalphBacon]

Yes, that seems to be the update in the GitHub:

Oddly, I've had no trouble with the call not being there! 😲

[SebastianKotstein]

I ran into the same issue. However, only removing/commenting mbedtls_md5_starts_ret() out worked in my case. If I replace me-no-dev/ESP Async WebServer@^1.2.3 with https://github.com/me-no-dev/ESPAsyncWebServer.git in platformio.ini the web server could not resolve any endpoint (I get a 404 Not Found for any URI).

[acsadamjozsef]

I could compiled, but it did not work for me with: "lib_deps = https://github.com/me-no-dev/ESPAsyncWebServer.git"

it just works like changing the decrapted lines to the new versions : mbedtls_md5_starts_ret(&_ctx); mbedtls_md5_update_ret(&_ctx, data, len); mbedtls_md5_finish_ret(&_ctx, _buf);

[sseruzaifa]

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.

thank you, saved my day

[Westcott1]

Thanks, worked for me too! Only mbedtls_md5_starts needed to be changed
