System information

• OS Platform and Distribution : Linux Ubuntu 18.04(host) , Debian buster(docker image)
• Compiler version : g++8
• MediaPipe version: 0.8.10.2
• Bazel version: 5.2.0

Describe the problem: I want to build the hand_tracking demo for RaspberryPi through docker. so I follow the instruction (https://github.com/google/mediapipe/tree/master/mediapipe/examples/coral#cross-compilation) to build the demo.

the step like this:

1. clone the mediapipe source and go into the directory

git clone https://github.com/google/mediapipe.git
cd mediapipe

2. build the docker image

make -C mediapipe/examples/coral PLATFORM=armhf docker

after image build, it will auto go into the docker container.

3. modify the Makefile(path: /mediapipe/mediapipe/example/coral/)

• remove the '--define MEDIAPIPE_EDGE_TPU=all'，because I do not need the Edge TPU
• add the --copt="-std=gnu99", because it will occur the error

4. build the hand_tracking demo.

make -C mediapipe/examples/coral \
BAZEL_TARGET=mediapipe/examples/desktop/hand_tracking:hand_tracking_cpu \
build

in the compilation process, the error like this: Complete Logs:

Hi @reolf, Have you looked at this similar closed issue #926 and comment. Thank you!

[reolf]

hi @kuaashish , I had looked, but it seems not the same error.

[kuaashish]

Hi @reolf, Could you confirm that you are able to build the Hello_world_example successfully as mentioned here. Thank you!

[reolf]

hi @kuaashish, I had tried to build the hello_world example. it's no problem. and can run on raspberryPi.

[kuaashish]

Hi @reolf, Currently only Face Detection and Object Detection models are available on the Edge devices. MediaPipe has limited resources for new features. We will let you know if there is any specific update on this request.

Please follow this issue #426 and #426(comment) for more information.

Thank you!

Are you satisfied with the resolution of your issue? Yes No

[mauricewells]

I had the same issue as reolf I tried to build hand tracking in the mediapipe repo, but got the error in XNNPACK If any solution, pls let me know it

[mauricewells]

Of course, I successfully built hand tracking for coral device(Mendel Linux=Arm 64bit), but I failed to build that for Raspberry Pi(Raspbian Arm 32 bit)
