libonnxruntime.so shared library for linux-arm32 ??

[narendra9079]

Can you please provide latest version libonnxruntime.so shared library for linux arm32. I tried building it from source ./build.sh --config RelWithDebInfo --build_shared_lib --parallel --compile_no_warning_as_error --skip_submodule_sync with this command but the generated libonnxruntime.so is not working.

Did you try the main branch? We had a bug in the last release.

No, you need to either find a ARM64 machine to build the code, or use cross-compiling. The "--arm64" flag is Windows only.

ok got it if i am building for linux-arm32 then I have to either build on arm64 architecture or I can cross compile from x86_64 architecure for linux-arm64.

Thank you so much for the help. I will update if i'll face any issue.

Hello,
I followed below steps to build libonnxruntime.so for arm:

• Installed the toolchain from https://developer.arm.com/downloads/-/gnu-rm and extractred and added the bin path to the my bashrc file.
  Then i created a tool.camke file in the onnxruntime directory with the following code:
  SET(CMAKE_SYSTEM_NAME Linux)
  SET(CMAKE_SYSTEM_VERSION 1)
  SET(CMAKE_C_COMPILER aarch64-linux-gnu-gcc)
  SET(CMAKE_CXX_COMPILER aarch64-linux-gnu-g++)
  SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
  SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
  SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
  SET(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)
  SET(CMAKE_FIND_ROOT_PATH /mnt/pi)

then I used the following command to build it cmake -Donnxruntime_ENABLE_CPUINFO=OFF -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE="/home/narendra/onnxMain/onnxruntime/tool.cmake" -S "/home/narendra/onnxMain/onnxruntime/cmake/"
This command is building the code but it is not generating the libonnxruntime.so except that it is generating many libonnxruntime.pc libcunstom_test_executionprovider.so kinda files.

can you please provide some opinion on it ??

https://onnxruntime.ai/docs/build/inferencing.html
from here I followed the instruction for cross compilation on linux.

Hello,
Is it supported?????
if we use
SET(CMAKE_C_COMPILER arm-linux-gnueabi-gcc)
SET(CMAKE_CXX_COMPILER arm-linux-gnueabi-g++)

these cross compilers instead of

SET(CMAKE_C_COMPILER arm-none-linux-gnueabihf-gcc)
SET(CMAKE_CXX_COMPILER arm-none-linux-gnueabihf-g++)

Because I want to build shared library for linux-arm32 without hard float.
