Geekbench fails on CentOS 7 current

Hi, just downloaded GB5 on my up-to-date CentOS7 and it fails to run because evidently it is not statically linked and missing a matching version of the libstdc++ (asks for "GLIBCXX_3.4.20" specifically).

perhaps you want to provide a static variant since CentOS7 isn't entirely uncommon.

    Try installing libstdc++ from CentOS 8 (just this library alone).

    just one tiny issue with that: CentOS 8 ain't out yet.

    Grab a package from Fedora 28 then - it'll probably work.

    I have Fedora 30 on a bare metal host and RHEL8 in a VM: Both work with Geekbench 5 w/o problems.

    Again, the issue is, that CentOS 7 is one of the most important and popular Linux platforms and will remain so for a couple of years while RHEL8/CentOS8 mature or appear.

    To publish a benchmark that aims at being a "reference" without support for one of the most important platforms is just plain neglegence and must be fixed.

    Do it sooner rather than later.

    We'll take a look to see if there's anything we can do to improve Geekbench 5 compatibility with CentOS 7. In the meantime, Geekbench 4 should work with CentOS 7 without issue.

    Hi John,

    I know Geekbench 4 works on RHEL/CentOS 7 and I have used it extensively to gather profiling information about the hardware I use.

    It's also why I was surprised to discover that Geekbench 5 doesn't work just as well there, given that it represents the vast majority of all corporate Linux workloads globally.

    Since I noticed in the past, that Geekbench 4 CPU results tended to favor Linux vs Windows on identical hardware often by quite a bit, I wanted to find out if that bias continues in GB5 or if newer code and all those stringent optimizations I had just paid for with the new version had solved that issue.

    Knowing that would have made it easier to do the full switch to GB5 and justify me rebuilding my profile results database to a GB5 baseline.

    Otherwise there'd be little reason for me to switch, when relative hardware comparability is all I want.

    I'd like to add my vote for fixing Geekbench 5 in CentOS 7.

    Using Geekbench 4 is a fine workaround for the moment, but I paid for Geekbench 5 so I'd like to be able to use it on my CentOS machine ;-). It's working great on most of my other systems.
