Support jna 4 #19

Closed lbeuster closed 7 years ago

lbeuster commented 7 years ago

Hi,

I tried out the syslog4j with unix-sockets on an arm-linux. Unfortunately the jna 3 impl doesn't support arm. And it was not possible to just change the dependency to jna 4 because the syslog4j class SocketAddr needed a change (only one line - and I didn't really know what I was doing ;)). 

@Override
protected List getFieldOrder() {
    return Arrays.asList("sun_family", "sun_path");
}

Without the change there was the following error:

java.lang.Error: Structure.getFieldOrder() on class org.graylog2.syslog4j.impl.unix.socket.UnixSocketSyslog$SockAddr does not provide enough names [0] ([]) to match declared fields [2] ([sun_family, sun_path])

Are there any plans to support jna 4?

Best regards Lars

No, there are currently no plans to support JNA 4.x or work on the server parts of this library at all. Graylog is only using some isolated parts (e. g. parsing) and we have not interest in maintaining the unused parts.

You might want to check out other forks of this library, e. g. https://github.com/NessComputing/syslog4j.
