Error using v0.8.0: libsignal-client

[alexsstyle]

Hello together,

if I try to use the new version of signal-cli I get the following error:
ERROR App - Missing required native library dependency: libsignal-client

How can I fix this?

Thanks and best regards,
Alex

Are you on a non x86 system (e.g. Raspberry Pi)? Then you need the new native library.
Build instructions can be found in the Wiki https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal

You can also use the binaries I created for my project here: https://github.com/bublath/FHEM-Signalbot in the armv7l directory (without warranty!). You will still need to follow the instructions above to replace the x86 libraries in the jar files.

[alexsstyle]

I'm on a x86 system. I'm looking for a "ready to use" release, also for the new group version. At the moment my system is not setup to compile projects by myself. But I think I have to do this, to get rid of this two problems.

[bublath]

I just upgraded my x86 system to 0.8.0 and its working without issues.
Make sure you have no old ilbraries somewhere and that permissions are correct.
If you want to try a Dbus installation, you can use the "signal_install.sh" script from my repository mentioned above (adjust the config in the beginning and run with sudo). It will additionally install some Perl stuff, but basically it will automatically do a system-wide Dbus installation and even guide through the registration process if required.

Thanks for your help. My operating system is Windows (10, Java 15.0.2). Maybe this is the problem.

I just dropped everything from signal-cli, unzipped it new, checked my path-definitions, did a reboot and still the same error when trying to execute the receive command, also as admin.

If I use the old version, 0.7.4, I can execute the receive command without problems.

[bublath]

Ok, sorry then I'm out. I'm not even sure if there is a way to create the native libraries under Windows. Use Linux :)

[alexsstyle]

I've depencies to other Windows based software, not available for Linux :-( I've built 0.8.0 by myself, but still the same problem. Will now try to build libsignal-client by myself.

[alexsstyle]

Did a build of libsignal-client-java and placed the signal_jni.dll in the java.library.path. Also the zkgroup.dll. Works fine now. Issue closed.

[bublath]

Can you place the .dll's somewhere and post the path? I guess other Windows users would appreciate that.

[alexsstyle]

I think I did the dirty way. I created a new folder called dll in the lib folder of signal-cli and placed there the two dll files. The files must be namend signal_jni.dll and zkgroup.dll.

The two files can be found in this download:
native_libraries.zip

Than I modified the signal-cli.bat file. As written in the wiki, there are different ways to tell Java where to find this libraries.

new variable definition for the path:
set LIBPATH=%APP_HOME%\lib\dll

add argument to the exec string:
"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %SIGNAL_CLI_OPTS% -Djava.library.path=%LIBPATH% -classpath "%CLASSPATH%" org.asamk.signal.Main %*

@alexsstyle Thanks for the information!

I just would like to add that I also had to go in both lib/zkgroup-java-*.jar and lib/signal-client-java-*.jar to delete the ".so" files at the root of each file (I used 7Zip to edit the JAR files). These are the default libraries and until I deleted those I still got the error message your initial issue is about.

Thank you very much, @alexsstyle and @TheRec!!! You rescue me!!! Without your signal_jni.dll and the instruction i would never manage this.

For future releases i can download the official libzkgroup.dll and rename it in zkgroup.dll. But the releases from libsignal-client include only the Source code. Is there a way to publish the signal_jni.dll always suitable to the latest release from signal-cli?

Perhaps the introduction "Provide native lib for libsignal" in the Wiki can somebody complete with your steps for Windows-User? Like that everybody quickly can find it. Perhaps it is the same solution for macOS-User??? Seems they have the same problems...

I did the other way with the java.library.path. I put the downloaded signal-cli-0.8.0 on the desktop and rename it in signal-cli. In Windows i add C:\Users\ ...\Desktop\signal-cli\lib\dll in path for the java.library.path. In future i have always only to rename the folder from signal-cli. Perhaps this will help somebody, too.

In this way i want to say @AsamK: this project is great! Many thanks for it!!!

Thank you everyone. Really nice work!
I did everything described by @alexsstyle and @TheRec. However, I still get the following error message when running the script:
"Error: Could not find or load main class Files\signal-cli-0.8.1\bin..\lib\dll
Caused by: java.lang.ClassNotFoundException: Files\signal-cli-0/8/1\bin//\lib\dll"
Any idea why this still happens? To be honest, I am quite a starter in programming.

thanks already in advance

signal-cli-0.8.1_kook.zip

Much thanks to @TheRec and @alexsstyle, i followed @alexsstyle soution of creating dll file in the lib folder then modified the .bat file, after doing everything worked correctly but suprisingly i tried running it again today and i got this error: "WARN App - WARNING: Support for new group V2 is disabled, because the required native library dependency is missing: libzkgroup
Missing required native library dependency: libsignal-client".
I tried removing the signal_jni.dll and zkgroup.dll, recompile it, i also used the native_libries.zip file compiled by @alexsstyle and still nothing, i also deleted everything, redownload them, recompile them and add them back but the error persist.

Anyone with a solution??
Thanks in advance...

Hello everyone, I read this post and thank you so much it is working for version 0.8.0.
Does someone has the dll files for windows for the latest version 0.8.4.1 ? Or is there a place to download them ?

Thank you so much :)

I've started a GitHub CI/CD that compiles the native libraries automatically when new signal-cli versions are released.
The windows version also patches the signal-cli.bat file to add the dir with the compiled .dlls to the java path. Everything should just work, download and run.

[GabyPCgeeK]

In Windows if you rename signal_jni.dll to libsignal_jni.so and zkgroup.dll to libzkgroup.so and replace the ones in the jars it works fine without having to add the java.library.path.

I tried a bunch of the things listed above, but couldn't get it working. I think the main issue is getting all the latest versions of signal-client and libzkgroup. I'm guessing the native_libraries.zip that @alexsstyle posted above are simply out of date at this point?

Someone (@exquo ) setup a pre-build process that worked perfectly for me to fix this issue on Windows:

https://github.com/exquo/signal-libs-build

I just went to the "releases" section and downloaded the "signal-cli-v0.8.5-x86_64-Windows.tar.gz" and extracted. It's got everything pre-built, so I didn't have to do any messing around with dlls, or anything. It worked out of the box!

Basically, from what I can tell, @exquo 's repo packages everything up nicely and adjusts things so you don't have to go digging around to compile and/or organize things together yourself. Read the directions on the README.md of that repo if you want more details.

Renaming signal_jni.dll to libsignal_jni.so in the JAR worked fine for me as well. Thx!
