I attempted to upgrade Calibre to the current production release.  It 
fails to run (I can post my question) but the response given is:

SL7 is based on RHEL7 and uses GCC 4.9 (see 
https://urldefense.proofpoint.com/v2/url?u=https-3A__access.redhat.com_solutions_19458&d=DwIGaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=VIryM0aQaNiX0n1xowynI6HPID-GSk5v8GbrCq2fldM&s=eWpq7f1FsG6R3tgnKBPi__pLLLgTrtRmzb2uWLpjkWg&e= ).

Solution?: wait for RHEL8, install a proper desktop linux distro or 
follow https://urldefense.proofpoint.com/v2/url?u=https-3A__developers.redhat.com_blog_2...gcc-2D8-2Dclang-2D6_&d=DwIGaQ&c=gRgGjJ3BkIsb5y6s49QqsA&r=gd8BzeSQcySVxr0gDWSEbN-P-pgDXkdyCtaMqdCgPPdW1cyL5RIpaIYrCn8C5x2A&m=VIryM0aQaNiX0n1xowynI6HPID-GSk5v8GbrCq2fldM&s=H94UEqdoz0IpzxgBa16hgbaiKAzxsoIQhIrbgUt9XbM&e= 

End quote.

I always thought that SL was a proper desktop (user interface GUI) 
Linux, and not just Debian/Ubuntu derivatives or SUSE.

Calibre needs RuntimeError: Failed to load icu with error: 
/lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by 
/opt/calibre/lib/libicui18n.so.64)

Is the required lib available for SL7 without disrupting the OS per se?

If not, does anyone know the last Calibre that does work with SL7?

Any help would be appreciated.
