JVB java error on Debian 10 ppc64el

[kop316]

Description

---

The normal Jitsi Meet install does not allow audio or video to happen on a Debian 10 ppc64el install

Current behavior

---

The jvb.log has the following health check failure:

Java.lang.NoClassDefFoundError: Could not initialize class org.jitsi.videobridge.sctp.SctpManager

Possible Solution

---

I am attempting to recompile jitsi-videobridge to see if a recompile on a native system will fix it.

Environment details

---

Debian 10 on ppc64el on a POWER9 system, with apache2 installed and a Let's encrypt Certificate.

I filed a jitsi-sctp issue requesting a ppc64le (aka ppc64el) build for jitsi-sctp. SCTP support does work on ppc64le if you build the shared object file yourself then include it at the correct path within the correct jar.

[fitzsim]

jitsi-srtp-1.1-12-ga64adcc.jar already contains ppc64le binaries:

linux-ppc64el/libjitsisrtp_1.1.so linux-ppc64el/libjitsisrtp_3.so

I needed to rename the linux-ppc64el directory within the jar file to linux-ppc64le, otherwise I would get:

JVB 2023-12-06 10:26:03.798 WARNING: [112] JitsiOpenSslProvider.<clinit>#66: Unable to load jitsisrtp java.lang.UnsatisfiedLinkError: no jitsisrtp_3 in java.library.path: /usr/java/packages/lib:/usr/lib/powerpc64le-linux-gnu/jni:/lib/powerpc64le-linux-gnu:/usr/lib/powerpc64le-linux-gnu:/usr/lib/jni:/lib:/usr/lib

After renaming the directory, I get:

JVB 2023-12-06 10:28:16.501 INFO: [109] JitsiOpenSslProvider.<clinit>#52: jitsisrtp successfully loaded for OpenSSL 3

and everything seems to work fine.

Overall, it seems like ppc64le support for Jitsi is really close to working. Just this folder naming issue -- maybe some systems do need linux-ppc64el, so a second linux-ppc64le directory could be added for compatibility? -- and the jitsi-sctp issue I filed need to be addressed.

It would also be nice if jitsi-videobridge provided linux-ppc64 binaries for big endian systems.

We don't use ppc, so we're unlikely to implement the suggested changes, but contributions are welcome

OK, I just posted jitsi/jitsi-srtp#49. I will work on a similar patch for jitsi-sctp.

Done, here is the pull request for jitsi-sctp: jitsi/jitsi-sctp#20.
