Raspberry Pi上的JNativeHook

Question

Am trying to use JNativeHook on the Raspberry Pi Platform

I have a simple java executable that works great on Mac and Windows, and I presumed should work fine on a Debian-based linux distribution....

However on-startup I get:

Exception in thread "AWT-EventQueue-0" java.lang.ExceptionInInitializerError

So I have to do something extra for this to work on Linux?

Answer 1

You need to recompile the native library contained in the jar to ARM. It should compile without any issues on Linux, use ant compile jar to build. If you want to file a bug report I will work with you to get an arm binary supported.
