找不到软件包“ google / protobuf”

Question

I am compiling an open source project written in go (openblockchain). I get the following error when I do go build. Can anyone help me with this issue

Compilation Error

> go build
../go/src/github.com/openblockchain/obc-peer/openchain/util/utils.go:28:2: cannot find package "google/protobuf" in any of:
    /usr/src/pkg/google/protobuf (from $GOROOT)
    /home/vichu/go/src/google/protobuf (from $GOPATH)

Additional Information

I referred the question here in Stack Overflow but still no luck in solving the issue. Here is some more information about what all I have:

Protoc version is up to date.

> protoc --version 
libprotoc 3.0.0

My environment variables

> echo $GOPATH
/home/vichu/go
> echo $GOBIN
/home/vichu/go/bin

Protobuf has been built using the README.

~/go/src/github.com/golang/protobuf$ ls
AUTHORS  CONTRIBUTORS  jsonpb  LICENSE  Makefile  Make.protobuf  proto  protoc-gen-go  proto.pb.go  ptypes  README.md

Update

I did the following Util.go in source code as mentioned in answer. The source code is open source and here is the link

-       gp "google/protobuf"
+       gp "github.com/google/protobuf"

When I do go get, the below is the error

> go get github.com/google/protobuf
can't load package: package github.com/google/protobuf: no buildable Go source files in /home/vichu/go/src/github.com/google/protobuf

Firstly, your import is wrong, you are trying to import a C++ package, not a golang package. It needs to be:

import ("github.com/golang/protobuf/proto")

If you don't have this package installed already, you need to run from command line:

go get github.com/golang/protobuf/proto
