I've already reported this problem in my Thread: CentOS 7.4 Troubles (
viewtopic.php?f=114&t=63495).
Looks like they don't check for CentOS compatibility.. Thats pretty odd since CentOS is the linux distribution that is used most in VFX.
CentOS 7.4 just provides older libs than the one that are needed to run OctaneBlender. So i could not find a way to make OctaneBlender run with whatever "yum" provides as was suggested by grimm. CentOS 7.4 is the latest version of CentOS. In general you can check with "yum whatprovides libname" if something in your repos contains what you need.
If you don't want to mess up your system be careful not to overwrite libs that your system provides. You still can use the old OctaneBlender version and export an .orbx - the latest Octane Standalone does work on CentOS 7.4 and gives you access to all the latest and greatest features.
I also put a request to generate an .appimage or .flatpak for exactly that reason.
Since then a version of OctaneBlender compiled with GLIBCXX_3.4.19 instead of GLIBCXX_3.4.20 would be great.

Everything else can be painfully solved... like getting python 3.5 (CentOS provides only 3.4) etc.
