java.lang.UnsatisfiedLinkError: Native library

[nmanhong]

The computer my school gave us is loongarch, but I am used to using clion, but using clion on loongarch cannot debug, which makes me very distressed, every time I debug, it will prompt "java.lang.UnsatisfiedLinkError: Native library (com /sun/jna/linux-loongarch64/libjnidispatch.so)" I searched the Internet and the problem is in pty4j, but I don't know how to do it, do you tell me, or you coud add loongarch support

@nmanhong Please reproduce the problem in CLion and share your idea.log (Help | Show Log in ...). Looks like JNA doesn't support Loongarch yet.

@segrey
Every time I debug, it will prompt the following error, but loongarch supports jna, but the architecture is different, and it cannot support the jna brought by clion, it seems like this, I don't understand it very well

/usr/bin/g++ Test.cpp -o Test
java.lang.NoClassDefFoundError: Could not initialize class com.sun.jna.Native

@nmanhong Maybe JNA version bundled with CLion doesn't support Loongarch, or maybe some other problem causes Could not initialize class com.sun.jna.Native. If you restart IDE, reproduce the problem and attach idea.log, it will be possible to find the cause. As I can see, recently a PR to JNA has been opened that adds support for Loongarch (java-native-access/jna#1406).

@segrey
I found that file, but the content in it is too long, I don't know how to find the cause of the error, can you help me?

[segrey]

@nmanhong You can shutdown IDE, delete your idea.log. Then, start IDE and reproduce the issue. Now idea.log will have a smaller size, so it can be attached here.

@segrey
I tried to do this, but there are still a lot, and I can't understand it, can you help me to find out the problem?

@nmanhong Thanks for the log. Unfortunately, it says that JNA doesn't support your OS. You can find a list of pre-built platforms here.

Looks like there are two ways: build JNA for your platform by yourself (according to https://github.com/java-native-access/jna#supported-platforms) or wait until JNA supports LoongArch.
