Running JSerialComm on M1 Mac. 'java.lang.UnsatisfiedLinkError'

[jimenezjose]

I already tried the following:

1. Use the latest JSerialComm jar file
2. Override the os.arch_full=armv8_64.

I am still running into issues.

It wasn't well documented, but the way I tried overriding the architecture was by using java -Dos.arch_full=armv8_64 -cp ...

Thank you in advance. I left the complete error at the bottom.

Here is the Makefile, and the run script

I also tried specifying a tmpdir -Djava.io.tmpdir=/Users/josejimenezjr/micromouse-simulator-temp

FYI, I just ran into the same issue myself after building the current source from scratch, then attempting to call SerialPort.getCommPorts():

Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot load native library. Errors as follows:
[1]: no jSerialComm in java.library.path: /Users/jeff/Library/Java/Extensions:/Library/Java/Extensions:/Network/Library/Java/Extensions:/System/Library/Java/Extensions:/usr/lib/java:.

Execution failed for task ':com.fazecast.jSerialComm.HighThroughputNullmodemTest.main()'.

NOTE: In order to get it to compile, I had to change sourceCompatibility and targetCompatibility (in build.gradle) from 6 to 7. This might (or might not) be significant.
