Building ONNXRuntime v1.8.0 on RPi Zero gives linking error #8062

Closed FamousDirector closed 1 month ago

FamousDirector commented 3 years ago

Describe the bug I am trying to build ONNXRuntime v1.8.0 on RPi Zero. During building I get a pthread linking error. Here is the full stack trace

Urgency None

System information

To Reproduce

Expected behavior The library to build...

Screenshots None

Additional context I am not picky on version either. If an older version of ONNX works then I will revert and build from source.

PS. I'd estimate the complete build time of this to be 14 hours on this device.

snnn commented 3 years ago

Could you please run "make VERBOSE=1" in /home/pi/onnxruntime/build/Linux/MinSizeRel and post the log here?

If build time is a concern, please try cross-compiling, which will only take a few minutes(vs 10+ hours).

snnn commented 3 years ago

As a quick fix, you may open cmake/CMakeLists.txt, Find https://github.com/microsoft/onnxruntime/blob/master/cmake/CMakeLists.txt#L1613

list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} Threads::Threads)

And change it to

list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} pthread)
FamousDirector commented 3 years ago

I'm a bit of a noob at cross compiling. How would I do this for an armv6 architecture?

snnn commented 3 years ago

https://www.onnxruntime.ai/docs/how-to/build/inferencing.html#cross-compiling-on-linux

FamousDirector commented 3 years ago

Okay so I followed those instructions and cross compiled the library with the following Dockerfile:

FROM balenalib/raspberry-pi-python:3.7-stretch-build

ARG ONNXRUNTIME_REPO=https://github.com/Microsoft/onnxruntime
ARG ONNXRUNTIME_SERVER_BRANCH=v1.8.0

# Build Output
RUN ls -l /code/onnxruntime/build/Linux/${BUILDTYPE}/*.so
RUN ls -l /code/onnxruntime/build/Linux/${BUILDTYPE}/dist/*.whl

RUN [ "cross-build-end" ]

However after copying the wheel file (onnxruntime-1.8.0-cp37-cp37m-linux_armv6l.whl) to the RPi Zero and running python3 -c "import onnxruntime" I get the error:

Illegal instruction
snnn commented 3 years ago

Sorry I don't understand the docker file. It was not written by me. I can't provider further help on it. It is not relevant to the build document I showed you.

FamousDirector commented 3 years ago

I modified it from the documentation here. I scrolled up in the document you send and got it from here.

kcoul commented 8 months ago

As a quick fix, you may open cmake/CMakeLists.txt, Find https://github.com/microsoft/onnxruntime/blob/master/cmake/CMakeLists.txt#L1613

list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} Threads::Threads)

And change it to

list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} pthread)

As it turns out, it's important to also add -pthread to compile options of all external libs as well. Below

function(onnxruntime_set_compile_flags target_name) add target_compile_options(${target_name} PRIVATE -pthread)

So, is it possible to install onnxruntime on raspberrypi zero or not? If yes, could you advice the steps to install? Please confirm!

Bump

snnn commented 1 month ago

nsync is removed. If you still see

undefined reference to `pthread_rwlock_wrlock'

Please go to the build folder and run

make VERBOSE=1 >& build.log

Then find the failed build command in the log file and post the full command here.
