Installation Stucks: newer GLIBCSS not recognized?

[Besi von Besmer]

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The confusing part: a newer version of this library seems installed.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

centos 7 is waaaaaaaaaaaay too old. Even centos 8 has reached end of life. Update your VPS.

[kovidgoyal]

Oh and if you want to check for the version, do this:

readelf -s /lib64/libstdc++.so.6 | grep CXXABI_1.3.8

Thank you for your quick reply

This is the smallest VPS found with only 256MB RAM and a few GB disc space. A sandbox. And as i am a really beginner, i try not to touch to much.

So what i've found:
calibre needs GLIBC >= 2.18 and libstdc++ >= 6.0.21

I guess this might a problem (related to your post):

[root@srv01 ~]# ls -l /usr/lib64/libstdc++.so.6
lrwxrwxrwx 1 root root 19 Apr 15  2021 /usr/lib64/libstdc++.so.6 -> libstdc++.so.6.0.19

so we're back at "updating the system" i guess

[Besi von Besmer]

readelf -s /lib64/libstdc++.so.6 | grep CXXABI_1.3.8

So shouldn't the part CXXABI_xxx be backward compatible?
I'm only talking about the GLIBCXX_3.4.19 listed, which seems newer than CXXABI_1.3.8 which is mentionned in the error-message.

@kovidgoyal. Does 3.48 also offer the calibre content server? will i be able to use newer versions installed on desktop PCs to connect to the "older" server?

[kovidgoyal]

desktop calibre doesnt connect to servers. And yes 3.48 has a server though its *much* less functional.

Connection Calibre to Server: Ah, you're right. This was a misunderstanding of mine. Thank you
