No such file or directory (Possible cause: architecture word width mismatch) #102

Trying to run jnaerator on ARMv8 (64 bit) and it sharts with the stack trace below. Is there a 64 bit ARM version libbridj.so I can hack into jnaerator jar? Or will this be fixed in jnaerator at some point?

I have a similar issue when running sarxos webcam-capture library on a aarch64 platform (Snapdragon 410c).

Just switch to HawtJNI and generate from C. JNI way faster than JNA any ways. I don't think they are going to ever fix jnarator https://github.com/sgjava/java-periphery uses HawtJNI.
