decode tripUpdates protocol buffer files using protoc.exe and the gtfs-realtime.proto

[Daniel]

Hi,

I'm trying to decode some tripUpdates protocol buffer files into a text
file.
I downloaded the gtfs-realtime.proto and the tripUpdates.pb files from
http://gtfs.ovapi.nl/new/ as well as the protoc.exe into the directory
"C:\test".

After executing the command

C:\test>protoc --proto_path=C:\test C:\test\gtfs-realtime-OVapi.proto
--decode=transit_realtime.OVapiTripUpdate C:\test\tripUpdates.pb

I always get the error:

com/google/transit/realtime/gtfs-realtime.proto: File not found.
gtfs-realtime-OVapi.proto: Import
"com/google/transit/realtime/gtfs-realtime.proto" was not found or had
errors.
gtfs-realtime-OVapi.proto:20:8: "TripDescriptor" is not defined.
gtfs-realtime-OVapi.proto:31:8: "VehiclePosition" is not defined.
gtfs-realtime-OVapi.proto:42:8: "TripUpdate" is not defined.
gtfs-realtime-OVapi.proto:52:8:
"transit_realtime.TripUpdate.StopTimeUpdate" is not defined.
gtfs-realtime-OVapi.proto:62:8: "VehicleDescriptor" is not defined.

What am I doing wrong?

Thanks,
Daniel

Clearly you need to download a file named "gtfs-realtime.proto" as well and
put it in C:\test\com\google\transit\realtime

Hey Daniel,

I'm trying to use the ovapi realtime feeds as well. I get the exact same
error is you and including gtfs-realtime.proto in the folder doesn't help.

Did you manage to solve this?
