Error on macOS : com.sun.jna.LastErrorException: [2] No such file or directory #9

win中一样，报这个错

Please tell us your MacOS version as well as the processor type (Intel or ARM) and your Mac model |
Did you run the example with administrator privileges? |
env: |
Under M1, the TUN device currently only runs with Rosetta. |
Is there any intention to be compatible with M1/M2 chips? |
We currently assume a bug in the JDK in connection with native calls and Apple Silicon. The native calls work without JDK under Apple Silicon. Which JDK are you using, and in which version? |
➜ netty-tun-examples git:(master) ✗ java -version This was upgraded 1 hour ago, before it was 11.0.15 |
|
I just released a new netty-tun version with the latest JNA release. This JNA version might fix your problem. |
After the upgrade or the same error, you can be sure that there will be a problem on the M1/M2 chip, or the error appears on the arm jdk |
Can you try this PR: netty/netty#12960 ? There we're using JNI and it should work under m1/m2. Only down side it's currently not merged into master |
Is there no hope for this library? netty is not very easy to compile |
I ran this example as an administrator, but I found the problem. It was a dll path problem that caused the error. |
Running with debug or java -jar gives the following error:
➜ target git:(master) sudo java -jar netty-tun-examples.jar echo
