Hi. As i didn't found an answer (or didn't see any relation in an answer to my problem nor did the solution help), i try my own post. I appologize if this is the wrong section or to specific to a system-setup rather than the calibre-project itself, please let me know.

Goal: Installing Calibre (Server) on a minimalistic VPS CentOS7 machine

Problem: Following the instructions under https://gist.github.com/plembo/337f3...3100692ae8c892, i get an error while downloading / installing:

ImportError: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /opt/calibre/lib/libicui18n.so.67)

The confusing part: a newer version of this library seems installed.

I already "tried" to add the path, where the symlink "libstdc++.so.6" is located, to the "LD_LIBRARY_PATH" environment variable...(as described here).

this looks like:

[root@srv01 ~]# env
LD_LIBRARY_PATH=/usr/lib64

I also tried with an ending "/". Same same

Shouldn't this be compatible to newer versions?
To mention, i'm a simple Linux user. There aren't to many skills in this domain.

Looking forward to any hints
