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).

list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} Threads::Threads)And change it to
list(APPEND onnxruntime_EXTERNAL_LIBRARIES ${CMAKE_DL_LIBS} pthread)

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

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
# Enforces cross-compilation through Qemu.
RUN [ "cross-build-start" ]
RUN install_packages \
sudo \
build-essential \
curl \
libcurl4-openssl-dev \
libssl-dev \
wget \
python3 \
python3-dev \
git \
tar \
libatlas-base-dev
# Carefully install the latest version of pip
WORKDIR /pip
RUN wget https://bootstrap.pypa.io/get-pip.py
RUN python3 get-pip.py
RUN pip3 install --upgrade setuptools
RUN pip3 install --upgrade wheel
RUN pip3 install numpy
# Build the latest cmake
WORKDIR /code
RUN wget https://github.com/Kitware/CMake/releases/download/v3.20.3/cmake-3.20.3.tar.gz
RUN tar zxf cmake-3.20.3.tar.gz
WORKDIR /code/cmake-3.20.3
RUN ./configure --system-curl
RUN make
RUN sudo make install
# Set up build args
ARG BUILDTYPE=MinSizeRel
# if doing a 64-bit build change '--arm' to '--arm64'
ARG BUILDARGS="--config ${BUILDTYPE} --arm"
# Prepare onnxruntime Repo
WORKDIR /code
RUN git clone --single-branch --branch ${ONNXRUNTIME_SERVER_BRANCH} --recursive ${ONNXRUNTIME_REPO} onnxruntime
# Build ORT including the shared lib and python bindings
WORKDIR /code/onnxruntime
RUN ./build.sh ${BUILDARGS} --update --build --build_shared_lib --build_wheel --parallel
# Build Output
RUN ls -l /code/onnxruntime/build/Linux/${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 instructionSorry 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.

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!

2 weeks 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.logThen find the failed build command in the log file and post the full command here.
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
bash build.sh --config MinSizeRel --arm --update --build --build_shared_lib --build_wheelExpected 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.
