Missing native libsignal-client in v0.8.4

[exquo]

Just installed the latest signal-cli release v0.8.4 and got

$ signal-cli receive
Missing required native library dependency: libsignal-client

This is on linux, and the previous signal-cli versions have worked fine without needing any manual steps from https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal.

I've checked, and the libsignal_jni.so is bundled in the jar file:

$ unzip -l signal-cli-0.8.4/lib/signal-client-java-0.8.1.jar | grep libsignal_jni.so 
	2432368  2021-06-02 18:55   libsignal_jni.so

So, not sure what's missing.

That's strange, which distribution and cpu architecture do you have?

I get the same error on Debian 10 (x86_64).

Debian 10 (x86_64)

ditto :)

I've tried to compile libsignal-client on my system. I've got an older version of rust, so I've encountered some errors. Will try again once I have a bit more time.

I have compiled the libsignal-client java library (turned out it requires the latest nightly release of the rust compiler), and replaced the original with it:

cd <...>/librust-client/target/releases
zip -u <...>/signal-cli-0.8.4/lib/signal-client-java-0.8.1.jar libsignal_jni.so

Now it works fine with signal-cli v0.8.4.

For the reference, here's the compiled binary file.
(I guess folks shouldn't use it in their production environments, since it's some unverified binary file coming from someone on the internet; but it might be useful for troubleshooting, in e.g. a virtual machine)

Let me know if I can do anything else to troubleshoot this on my system.

Maybe upstream now compiles on a newer distribution, with a more recent libc version than debian 10 has ...
I can check it later.

I get the same error on Debian 10 (x86_64).

Same here.

yep, upstream libsignal-client builds the library with ubuntu latest, which has a newer glibc version.
The provided binaries now require at least glibc 2.29 and Debian 10 has glibc 2.28 ...

$ objdump -T libsignal_jni.so | grep GLIBC
0000000000000000      DF *UND*  0000000000000000  GLIBC_2.29  log

Another case of this (CentOS 7): #606 (comment), #413 (comment)
