junixsocket-native not loading

Farhan Khan

Farhan Khan

Hi all,
This is a long-shot, but anyone know why the library junixsocket-native might not load on FreeBSD? I am using OpenJDK 13, and have tried every available version on FreeBSD 12.1-RELEASE-p2. I am trying to run the package 'signald', but this appears to be the only (at least current) error I am running into.

I am using junixsocket version 2.3.1.

Code: 
[root@signald ~/signald/lib]# java -classpath $APP_HOME/lib/signald.jar:$APP_HOME/lib/signal-service-java-2.13.9_unofficial_1.jar:$APP_HOME/lib/bcprov-jdk15on-1.64.jar:$APP_HOME/lib/junixsocket-common-2.3.1.jar:$APP_HOME/lib/junixsocket-native-common-2.3.1.jar:$APP_HOME/lib/sentry-log4j2-1.7.30.jar:$APP_HOME/lib/log4j-core-2.13.0.jar:$APP_HOME/lib/log4j-api-2.13.0.jar:$APP_HOME/lib/slf4j-nop-1.8.0-beta4.jar:$APP_HOME/lib/picocli-4.2.0.jar:$APP_HOME/lib/signal-metadata-java-0.0.3.jar:$APP_HOME/lib/signal-protocol-java-2.7.1.jar:$APP_HOME/lib/protobuf-java-2.5.0.jar:$APP_HOME/lib/libphonenumber-8.10.7.jar:$APP_HOME/lib/jackson-databind-2.9.9.2.jar:$APP_HOME/lib/okhttp-3.12.1.jar:$APP_HOME/lib/threetenbp-1.3.6.jar:$APP_HOME/lib/sentry-1.7.30.jar:$APP_HOME/lib/slf4j-api-1.8.0-beta4.jar:$APP_HOME/lib/jackson-annotations-2.9.0.jar:$APP_HOME/lib/jackson-core-2.10.0.jar:$APP_HOME/lib/okio-1.15.0.jar:$APP_HOME/lib/curve25519-java-0.5.0.jar io.finn.signald.Main

Please also see, the junixsocket jar files exist. Any ideas?

Code: 
[root@signald ~/signald/lib]# pwd
/root/signald/lib
[root@signald ~/signald/lib]# ls junixsocket*
junixsocket-common-2.3.1.jar        junixsocket-native-common-2.3.1.jar
 
I apologize, I posted in haste yesterday. I have two junixsockets in my test jail now. The first is one I compiled myself after quite a few typecasts, just to see if it would work. This does not have any libraries. The second is the one that signald, the package I am ultimately trying to use, has in its lib directory. The second has what you referenced but note the lack of FreeBSD

First:

I should add, in the compiled directory I have what appears to be the compiled object file junixsocket/junixsocket-native/target/nar/junixsocket-native-2.3.1-amd64-FreeBSD-gpp-jni/lib/amd64-FreeBSD-gpp/jni/libjunixsocket-native-2.3.1.so. Is there a way to manually add it to a jar file?
 
You need to pass -Dorg.newsclub.net.unix.library.override=<library-path> to the JVM process. Java programs tend to come with annoying wrapper shell scripts, which often mess those arguments, so that might take a few attempts to get right. You can verify the passed arguments with visualvm.
