It seems you are either missing gcc or are missing the library paths to where gcc is located.
Try running the following command (sudo may be required)

yum -y install gcc

Try running it at this point, or try using:

export LD_LIBRARY_PATH=/usr/local/lib:/usr/lib:/usr/local/lib64:/usr/lib64

and try again

Hmm, it seems that I need to link C++ runtime statically on Linux too.
I do this on Windows to support everything from XP to W10.

Will do

@SonnyX No, it's not about GCC or a missing library. It's about the Dual ABI.

@c-smile I am not sure that this is a good idea to link libc++ statically in a shared library: https://stackoverflow.com/a/44809374

The Dual ABI document also says this:

This commonly happens when linking to a third-party library that was compiled with an older version of GCC. If the third-party library cannot be rebuilt with the new ABI then you will need to recompile your code with the old ABI.

The source issue is from here: sciter-sdk/go-sciter#237

I can try to recompile Sciter under different conditions and test on various OS. Will do.
