undefined reference to `esp_aes_init'

I'm following the "rename main" component instructions in the documentation, but have gotten stuck on the following errors:

your missing


btw:
did you check menuconfig "USE_MBEDTLS_CRYPTO" ?

best wishes
rudi

[permal]

I do have WPA_MBEDTLS_CRYPTO, which presumably enables USE_MBEDTLS_CRYPTO

Disabling WPA_MBEDTLS_CRYPTO allows the project to compile, but that's not what I want.

Hi Permal,

Exactly which version of IDF do you have ("get describe --tags")? Could you please post the full output from a CMake run? (Either running CMake directly or running "idf.py reconfigure" in your project.)

[permal]

v4.0-dev-1443-g39f090a4f
tensa-esp32-elf-gcc (crosstool-NG esp32-2019r1) 8.2.0

CMake output attached.

[ESP_Angus]

Hi permal,

Thanks for those details.

I forgot that your project is a CMake project that integrates IDF as an external library. My guess is that this is why something is not building properly.

Is there a branch of your project that I can check out to reproduce this error?

Angus

[permal]

Angus,

That's the ting - it's not any longer. I've spent the weekend redoing my build system so that it follows IDF's component-based variant when building for the ESP (too much hassle using IDF as a lib when it is removed two steps from the main app). The only thing I'm doing differently is that I don't have a "main" folder so I'm following the instructions on how to build without a "main"-folder.

So, you can checkout the latest master (https://github.com/PerMalmberg/Smooth), run menuconfig to enable the Wifi supplicant to use mbedtls and just compile it as you would any other IDF-project. It'll compile the SNTP test project out-of-the-box.

[ESP_Angus]

With commit 329bdf56881e113d3d1715255b1c83926b9e7843 and no config changes I get the following :

Code: Select all

I did just realise that a fix was committed internally which might address this problem (commit 6875080b9bcb65e435c23017286fb1a7480b4c41), and hasn't pushed to GitHub master branch yet due to a CI problem but should appear the next time master branch updates, hopefully in the next day or so.)

[permal]

Hm, that's odd. I'm sure I tested the sntp test before posting my reply. :\ Will check if I get the same in a completely fresh clone.

Looking forward to the next sync

[ESP_Angus]

Github master has updated, so if you can then please try again with latest master (commit 02c7c38)
