Attempts to install gRPC on a CentOS 7 server fails.
gRPC fails to compile because GCC is required to be version 6.3 or greater. CentOS 7 provides by yum RPM packages version 4.8 presently.
There is no workaround available on a CentOS 7 server. A newer operating system like AlmaLinux 8 will be needed. AlmaLinux, for example, currently, November 2022 has GCC version 8.2.
