Can you tell me how to solve it?

Sorry, I have no idea what SPG is. Doesn't the wheel work for you? I published aarch64 wheels, which are built with a CI.

@saghul how can I install pacares@4.0.0,but python3 setup.py build failed in pycares@4.0.0 on centos8_aarch64. Can you tell me how to solve it?
