Compile grpc with C++11-only compiler support

[Jeremy Pallotta]

The latest versions of gRPC require compiler support for C++14.

I need to use gRPC with CentOS 7's native compiler, gcc 4.8.5, which supports most of c++11.  What is the latest version of gRPC that doesn't require c++14 support?

Thanks in advance.

gRPC 1.46 was the last version supporting only C++11.

I had tried to compile grpc version 1.34.0 using gcc 4.8.5; however, I ran into an issue with absl.  Error is below.  I can compile grpc 1.30.2 using gcc 4.8.5.  Perhaps absl has some c++11/C++14 feature that is not supported by the gcc 4.8.5 compiler?

Thanks for the information regarding gRPC 1.46.
