Compilation error

[doncwilliam]

I am using Ubuntu 16.04, and R 3.4.4.

I tried to follow the installation instruction (https://github.com/nfultz/grpc/blob/master/install) with no problem.

I also try to install the R package following (https://github.com/nfultz/grpc/issues/18)

R CMD build grpc/
R -e "install.packages(dir(pattern = 'grpc.*.tar.gz'), repos=NULL)"

However, during compilation, I get the following error. Do you know how I may solve the problem?

> install.packages(dir(pattern = 'grpc.*.tar.gz'), repos=NULL)

Thank you! Don

Based on

client.cpp:13:23: error: ‘grpc_slice’ was not declared in this scope

Maybe you don't have the grpc library available?

[nfultz]

You might also check the Docker files for alternative build instructions, they are somewhat more current.

[doncwilliam]

Thank you for your help!

[nfultz]

What did you do to fix it? I could update the instructions.
