While linking undefined reference to functions from dl_lib_matrix3d.h and dl_lib_matrix3dq.h about esp-dl HOT 6 CLOSED

In what situation did you meet that ? Please add more information, or is there a problem with the default esp-who example ?

from esp-dl.

Thank you for prompt reply
Yes, it's a problem with the default esp-who example (Should I open this issue at esp-who git repo?).
When ESP-WHO Face Detection is enable in Camera Web Server config, it fails to build at linkage (otherwise it's ok).
I guess libdl_lib.a misses something.
BTW, I use esp-idf previously installed to my esp root dir (not the one attached to esp-who git) but without face detection all builds well

Hi, thanks for finding the bug, please update the esp-who with 27e8cde. It may solve your problem.

Did not helped, see my steps.txt attached

Did I make git update wrong?

from esp-dl.

call git submodule update

from esp-dl.

thanks you for being supportive

the issue was that I used the latest extensa toolchain (which is installed with latest esp-idf)
so to build successfully it is not enough to switch to esp-who/esp-idf
but one also needs to switch to previous toolchain

I succeeded with https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-80-g6c4433a-5.2.0.tar.gz
