Lexactivator looking for wrong libLexActivator.so lib in python with aarch64-linux-gnu

rahultv · January 15, 2021, 2:33pm

I have installed cryptlex.lexactivator with pip and tried to use it from python side. but iam geeting “OSError: /home/user/.local/lib/python3.6/site-packages/cryptlex/lexactivator/libs/linux/gcc/x86_64/libLexActivator.so: cannot open shared object file: No such file or directory”.
My analysis is that cryptlex should look for “gcc/arm64” folder instead of x86_64 since iam working in a machine with aarch64-linux-gnu target.

It will detect the correct library when you run it on the arm machine. Running on an x86_64 cpu won’t detect the arm arch.

Hello, I am running in correct architecture(arm machine not on x86_64) but it is not detecting.

Hi,

Can you please check the value of machine returned on your machine in the following line:

github.com

cryptlex/lexactivator-python/blob/master/cryptlex/lexactivator/lexactivator_native.py#L24


        return type
    else:
        return c_void_p
def is_os_64bit():
    return platform.machine().endswith('64')
def get_arch():
    is_64bits = sys.maxsize > 2**32
    machine = platform.machine().lower()
    if 'arm' in machine:
        if is_64bits:
            return 'arm64'
        else:
            return 'armhf'
    elif is_64bits:
        return 'x86_64'
    else:
        return 'x86'

Hello, the machine value iam getting is “aarch64”.
Iam running this code from nano jetson device.

Following are the specification:
processor: ARMv8 Processor rev 1 (v8l) × 4
Os type : 64-bit
