voltha-protos

Protobuf files used by VOLTHA.

Currently this is used to generate both go and python.

Protobuf definition files are located in protos/voltha_protos directory. This directory heirarchy and import scheme is required to allow the python code generated by the GRPC compiler to have the correct import paths.

NOTE: The protos/google/api directory has files copied from the Google APIs, and is only included for initial compilation of the VOLTHA protobuf files - these API's should be installed independently via either the python googleapis-common-protos package or the golang go-genproto repo.

Go environment

Get the Voltha-protos repository:

git clone https://gerrit.opencord.org/voltha-protos
cd voltha-protos

Setting up the Go environment

After installing Go on the MAC, the GOPATH environment variable should be set to ~/go. Create a symbolic link in the $GOPATH/src tree to the voltha-go repository:

mkdir $GOPATH/src/github.com/opencord
ln -s ~/repos/voltha-protos $GOPATH/src/github.com/opencord/voltha-protos
