error: unused parameter 'head' [-Werror=unused-parameter]

[yv5125]

Hello!

I'm trying to build plcontainer on Ubuntu 18 with gpdb 6.7.1 as described in the README step by step.

I already done:

Build and install PL/Container GPDB backend client Get the code repo

git clone --recursive https://github.com/greenplum-db/plcontainer.git

Install the third-party libraries

Protobuf and gRpc

git clone --recursive --branch v1.24.3 --depth 1 https://github.com/grpc/grpc.git cd grpc/third_party/protobuf ./autogen.sh ./configure make -j sudo make install export LD_LIBRARY_PATH=/usr/local/lib/:$LD_LIBRARY_PATH cd ../.. make -j sudo make install

Build and Install

cd plcontainer make docker-dep make proto

And now when I do make I've got an error:

root@dwgpdb:~/git/plcontainer# make

@HaozhouWang could you please help me to solve this?

Thanks!
