Errors running on Oracle Enterprise Linux 7 (same as CentOS 7) x86_64

[russoisraeli]

When running either the provided binaries for Linux x86_86 (Oracle Enterprise Linux 7 - OEL 7/CentOS 7), OR building and running from source, the following errors show:

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

It looks like there's a library dependency issues. I extracted libzkgroup.so, and libsignal_jni.so from zkgroup-java-0.7.0.jar and signal-client-java-0.2.3.jar:

$ ldd libzkgroup.so
./libzkgroup.so: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by ./libzkgroup.so)

$ ldd libsignal_jni.so
./libsignal_jni.so: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by ./libsignal_jni.so)

Building and updating libzkgroup.so in the JAR, helps the first warning. However, I cannot solve the second error.

Please help.

The bundled .so files require a more recent glibc than provided by CentOS 7.
You need to compile both libzkgroup.so and libsignal_jni.so.

Hello Asam,

I did build the two libraries and update the JAR file. After that the libzkgroup.so warning disappears, but the libsignal error persists.

I followed the instructions in https://github.com/AsamK/signal-cli/wiki/Provide-native-lib-for-libsignal to the T, and I get --

$ ./signal-cli --verbose link
2021-05-12T18:10:36.366-0400 [main] INFO LibSignal - [libsignal-client]: rust/bridge/jni/src/logging.rs:173: Initializing libsignal-client version:0.5.1
Missing required native library dependency: libsignal-client

I tried depositing the library separately, use LD_LIBRARY_PATH (and/or install it via /etc/ld.conf.d/, ldconfig) and it makes no difference.

[AsamK]

Go to the releases page and download the source for the libsignal-client version used by signal-cli (Check the version of signal-client....jar in the signal-cli lib folder - as of 1st May 2021 its java-0.2.3 release).

[russoisraeli]

Thank you so much! Certainly in business now

Can anybody help me to run it on centos 7?
I've downloaded signal-cli 0.9.0 binary and downloaded and compiled libsignal-client (cargo buld) but i'm still receiving this:
