使用golang / protobuf时在数据存储区中生成错误

Question

I have an application which uses both bigquery and cloud datastore APIs. I use glide for go package management. I keep seeing build errors with either bigquery or datastore depending upon the version of golang/protobuf that I use. I am not able to find a version that is compatible with both bigquery and datastore. Either one of the packages keeps failing to build.

Build errors in datastore while using golang/protobuf version 7cc19b78d562895b13596ddce7aafb59dd789318:

../../vendor/google.golang.org/genproto/googleapis/api/annotations/annotations.pb.go:33: undefined: proto.ProtoPackageIsVersion2 ../../vendor/google.golang.org/genproto/googleapis/api/annotations/annotations.pb.go:41: unknown proto.ExtensionDesc field 'Filename' in struct literal ../../vendor/google.golang.org/genproto/googleapis/api/annotations/annotations.pb.go:48: undefined: proto.RegisterFile ../../vendor/google.golang.org/genproto/googleapis/api/annotations/http.pb.go:540: undefined: proto.RegisterFile Build errors in bigquery while using golang/protobuf version 8ee79997227bf9b34611aee7946ae64735e6fd93:

Opened an issue here - https://github.com/GoogleCloudPlatform/google-cloud-go/issues/475. Any pointers would be appreciated.

You did the right thing by filing a bug, so hopefully that will be resolved soon. The most recent version of the cloud APIs adds support for query parameters but based on the error that you are seeing, one of the libraries was not updated properly.
