Undefined reference to `SINRICPRO_2_9_12::signMessage

[eos1d3]

Using Smart Light example with VS Code. Device is ESP32 Dev board. After complied, there is error message after linking:

Linking .pio/build/esp32dev/firmware.elf

[env:esp32dev] platform = espressif32 board = esp32dev framework = arduino lib_deps = sinricpro/SinricPro @ ^2.9.17 ArduinoJson@~6.11 WebSockets fastled/FastLED @ ^3.5.0

Tried with 2.9.12 - 2.9.17, both has same error.

Please clean the build directory (PlatformIO: clean) and try again.

[eos1d3]

Thank a lot for prompt reply.

I did many times to clean it, and even delete the whole .pio folder. But the problem is still the same.

Running latest version of PIO on Mac Big Sur. All other ESP IDF, Arduino projects run fine.

[sivar2311]

There must be some build artifacts somewhere. I cannot reproduce this. Everything is compiling fine here.

Do you have the same issue using one of the example sketches?

[eos1d3]

I have a lot other Arduino projects, all run fine. I just tried to delete the project and create another one, same problem.

I do find SinricProSignature.h and SinricProSignature.cpp files. And they are used during compilation.

I have just create another project AGAIN, I got the same error.

I can compile in Ubuntu VM just fine.

[sivar2311]

I do find SinricProSignature.h and SinricProSignature.cpp files. This is correct.

Please check if you have any global installations of SinricPro library. In PlatformIO you can isntall libraries to a global scope and/or to every project itself.

I guess there might be some leftovers from a global installed library.

[sivar2311]

I can compile in Ubuntu VM just fine.

This reinforces my opinion that something is wrong with the build environment (leftovers etc).

[eos1d3]

With your example above, I found I am using older ArduinoJson version.

After changing to ArduinoJson@^6.19.1, it works now!

Thanks a lot!

[sivar2311]

Good that it is working for you :) @kakopappa thanks for the assistance 👍

Usually the library dependencies are installed automatically and there should no necessary to set a specific version in the project's platformio.ini. See here: https://github.com/sinricpro/esp8266-esp32-sdk/blob/bed36f1b3ef662cf78581bbe0c3b4bae381364ac/library.json#L22-L31

Do you have a specific ArduinoJson version set in your platformio.ini? (Then this could lead to an incompatibility)

[eos1d3]

Hi, the root cause is from here:

https://github.com/sinricpro/esp8266-esp32-sdk/blob/master/examples/platformio/platformio.ini

You better change this setting to stop people using the wrong one again. I just copied it without checking it is old version.

[sivar2311]

Thanks for the info 👍 I will change the provided platformio.ini file in the examples.

[sivar2311]

platformio.ini is now fixed in 2.9.17] (master branch, not released yet)

Thank you for your contribution!
