Couldn't compile on CentOS 7

compilation terminated.

CentOS 7 doesn't ship with a recent enough glibc, so that sys/random.h isn't actually available. I saw that this is manually configured here. The libc in my system is:

I confirmed that PR #22 works 🎉 Thanks a lot! (maybe also better to modify GitHub action to include the OS?)

Thank you for confirmation!
I merged #22 and released as v0.0.5.

Yes, I think it's better to add OS type to GitHub action. ( And I welcome PR ...! 😄 )
