I have a class that I wish to protobuf. in that class one of the fields is an enum (in a class of it's own). Can I avoid defining an identical enum value in my .proto file ? Or will I have to manually make sure the enum definition in the java code is the same as in the .proto file? java code: public enum Location { UNDEF(0),HOME(1), WORK(2); ... } .proto file corresponding code: message Address{ enum location { UNDEF = 0; HOME = 1; WORK = 2; } optional location addressLocation; ... } The best solution for keeping things like this in sync is often code generation; determine which of your

How to build Google protobuf (c++ version, https://github.com/google/protobuf/releases/latest ) with Android target? I compiled protobuf without ndk-build. Here's the script (not very clean but it works): rm -rf /tmp/protobuf-3.3.0/ tar xzvf ~/Downloads/protobuf-cpp-3.3.0.tar.gz -C /tmp/ cd /tmp/protobuf-3.3.0/ export NDK_ROOT=/home/user/SDKS/ANDROID/NDK/android-ndk-r13b export SYSROOT=$NDK_ROOT/platforms/android-9/arch-arm export PREBUILT=$NDK_ROOT/toolchains/arm-linux-androideabi-4.9 export LDFLAGS="--sysroot=$SYSROOT" export LD="$NDK_ROOT/toolchains/arm-linux-androideabi-4.9/prebuilt/linux

When I am sending a protobuf variable through socket communication on recv end I am trying to display the string variable of protobuf I got segmentation in this remaining Data type other than String they are working fine but string variable case I got segmentation How can I over come in Protobuf string datatype segmentation fault other than we have any other data type for store the string data type. I create a example.proto with in string variable name is there I am compile example.proto with protoc compiler ( protoc example.proto --cpp_out <path> ) it create two files two files example.pb.h,

I have installed the libprotobuf-dev=2.6.0-4 and protobuf-compiler=2.6.0-4 packages from Debian Jessie repository. Now I'm trying to compile a program that use the 'addressbook.proto' file from the Google Developers example with the MinGW-w64 compiler. I'm using Ubuntu 14.04. With this command the program works: $ g++ main.cpp addressbook.pb.cc -lprotobuf But I want to compile for Windows too. I added the symlink: /usr/include/google -> /usr/i686-w64-mingw32/include/google . $ i686-w64-mingw32-g++ main.cpp addressbook.pb.cc -lprotobuf /usr/bin/i686-w64-mingw32-ld: cannot find -lprotobuf

I'm trying to compile TensorFlow after checking out the repo. I've reached a point where I'm stuck with google protobuf errors: INFO: From Compiling tensorflow/core/kernels/histogram_op_gpu.cu.cc: ./tensorflow/core/lib/core/status.h(32): warning: attribute "warn_unused_result" does not apply here external/protobuf_archive/src/google/protobuf/arena.h(719): error: more than one instance of overloaded function "google::protobuf::Arena::CreateMessageInternal" matches the argument list: function template "T *google::protobuf::Arena::CreateMessageInternal<T>(google::protobuf::Arena *)" function

I have a google protobuf file from OpenStreetMap , specifically I have the 1.4MB Liechtenstein country extract from Geofabrik . The protoc command says it "write the raw tag/values to stdout" with the --decode_raw option. However I keep getting this error: $ cat liechtenstein-latest.osm.pbf | protoc --decode_raw Failed to parse input. I have compiled and installed the protobuf library direct from Google, version 2.6.1 which is the current one. This file is valid, various OpenStreetMap tools that read pbf files ( osm2pgsql , osmosis ) can read it fine. What could be wrong? How can I get -
