What is the minimum Linux Kernel and gcc version for cross-compiling?

[embedde...@gmail.com]

I have an older ARM7 device that I would like to run gRPC on, but I have run into issue after issue getting the source code to cross-compile.  I would eventually like to use this device with Google Cloud Speech API streams and need gRPC++ for communication.  This is my system's setup:

    Target:

        gRPC-release-0_11_0

        protobuf-2.5.0

        Linux Kernel 2.6.37

        arm-none-linux-gnueabi-gcc-4.3.3

    Host:

        Ubuntu 16.04 4.4.0-116-generic Linux x86_64  

        gcc (Ubuntu 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609

Can anyone say with certainty that gRPC will or will not work with my device?  If my system is too outdated, what are the current recommended minimum requirements?

I really appreciate any help I can get.  I've been trying to get this to build for a few days now without any success.

Thank you!
