host_lib Whl for ARM64 Linux

Hello, I'm having issues running the example code on my Raspberry PI 4. I currently use Ubuntu 20 and the processor is ARM64. Do you have an appropriate whl file for ARM64 Linux? I believe the one included already is meant for Intel x86-64. Thanks!

Hi,

Did you run https://github.com/kneron/host_lib/blob/master/pkgs/kdp_host_api-1.1.2_Raspbian_-py3-none-any.whl in your Raspberry pi 4? We build this natively in Raspberry pi 4 in Raspian OS, which is the default OS for Raspberry pi 4. Could you try that? If it is not work, please post your error message here.

I have a requirement to use Ubuntu. When I used the Raspbian whl I got the following error: OSError: /home/edge/.local/lib/python3.8/site-packages/kdp_host_api/libhostkdp.so: wrong ELF class: ELFCLASS32

When I use the Linux whl, I get the following error: OSError: /home/edge/.local/lib/python3.8/site-packages/kdp_host_api/libhostkdp.so: cannot open shared object file: No such file or directory

I have verified that the package exists in that location though. I believe it's a matter of incompatibility of the targeted OS being Intel x86-64 and the actual hardware being Aarch64/ARM64.

Hello I wanted to follow up on this ticket. Is there anyway you can cross-compile your library to run on ARM64?
