Native library in Karaf

Hi,

How can I make Karaf to see Netty native library?
I'm using Cassandra java driver complaining against
missing libnetty_transport_native_epoll_x86_64.so

2021-03-11T21:23:04,069 | WARN  | FelixStartLevel  | NettyUtil
           | 612 - com.datastax.driver.core - 3.10.2 | Found Netty's native
epoll transport in the classpath, but epoll is not available. Using NIO
instead.
java.lang.UnsatisfiedLinkError: could not load a native library:
netty_transport_native_epoll_x86_64

Best regards

Thank you,

I just added the shared library file to the expected location inside the
bundle and it works now.

Regards

HI Daniel,

If you are using bundle, you have the Bundle-NativeCode allowing to define the location of dll/so lib.

It’s also possible to add at Karaf global level (java.library.path).
