Also upgrades signal cli to 0.12.1 since it failed to build previously (couldn't find signal-cli-native of 0.12.0).

Contributes towards #365

One thing to note on this. This worked on my Docker macOS arm64, but failed on prod Ubuntu x86_64 machine with:

WARN  Manager - Failed to call libsignal-client: Can't load library: /tmp/1243969752656717

I wanted to try out newer LIBSIGNAL_CLIENT_VERSION=0.30.0 but couldn't find where I can get the files for ext/libraries/libsignal-client/v0.31.0.

Possibly relevant AsamK/signal-cli#1305

Many thanks for the PR!

I'll wait until the CI is finished, but to me it looks good!

Regarding your issues: Which mode did you use on your x86-64 machine? the native mode?

regarding libsignal-client v0.31.0: I always try to stay at the same version that signal-cli comes packaged with. Newer versions might work, but I think it is the safest approach to use the same version as the pre-packaged signal-cli :)

You're welcome!

Gotcha. Where do you see which version it's packaged with?

One thing I forgot to mention, I would very much appreciate if you'd ping me once this is on Docker Hub. I think it might be something with my image being built differently so I'd love to try out the "official" build.

Native mode

ok, then it could indeed be GraalVM related.

It is mentioned in the signal-cli release changelog and verified again in the dockerfile.

I'll try, if I do not forget. You can btw. also watch this github repository for a new release (see https://github.blog/changelog/2018-11-27-watch-releases/). I'll always create a new github release when a new release is ready and the image is pushed to dockerhub. But maybe I can get docker image up for beta testing sooner, in that case I'll let you know :)

[k-bx]

I’m watching all commits and releases so should be good :)

I was just creating a ticket for this issue. We have been testing out the 0.68-pre release and ran into the issue with libsignal in native mode as well.
