[ajtwlsdlqp]

Hi, I tried to porting esp32-s3-eye example to my target board target board also same esp32s3 N8R8 so, i need your help.

Eclipse (2022-09 (4.25.0)) ESP-IDF 4.4.3 ESP32S3-N8R8

human face detection, color detection, move detection are working well on my board, but when i try to add recognition, i got this type error

d:/develop_tool/espressif/tools/xtensa-esp32s3-elf/esp-2021r2-patch5-8.4.0/xtensa-esp32s3-elf/bin/../lib/gcc/xtensa-esp32s3-elf/8.4.0/../../../../xtensa-esp32s3-elf/bin/ld.exe: my_Proj_Path\libmfn.a(mfn112_1x_model_s8.cpp.obj): in function int* std::__copy_move<false, true, std::random_access_iterator_tag>::__copy_m<int>(int const*, int const*, int*)': /home/yuanjiong/.espressif/tools/xtensa-esp32s3-elf/esp-2021r2-8.4.0/xtensa-esp32s3-elf/xtensa-esp32s3-elf/include/c++/8.4.0/bits/stl_algobase.h:368: undefined reference todl::nn::add2d(dl::Tensor&, dl::Tensor&, dl::Tensor&, dl::Activation const*, std::vector<int, std::allocator > const&, int)'

there are no error when i try to include header files

my partition tble

i thinks build size also enough

i add esp-dl to submodule and i have that static library

when i call

if CONFIG_MFN_V1

if CONFIG_S8

FaceRecognition112V1S8 *recognizer = new FaceRecognition112V1S8();

elif CONFIG_S16

FaceRecognition112V1S16 *recognizer = new FaceRecognition112V1S16();

endif

endif

this function that error came out..

Thanks, Best Regards

Hi, Can you run the origin example https://github.com/espressif/esp-dl/tree/master/examples/face_recognition successfully?
