Do you plan to link statically or dynamically against the protobuf library? If you can link against it statically, I think you may find that the linker is able to remove a lot of unused code. For Android (which is an environment where we care a lot about code size), what we generally do is: - Use lite protos only (i.e. set option optimize_for = LITE_RUNTIME in every .proto file) - Link against libprotobuf-lite and not libprotobuf - Pass -ffunction-sections and -fdata-sections to the compiler and -Wl,-gc-sections to the linker to maximize the linker's ability to strip out unused code
