How do I install protobuf in a ubuntu 16.04 environment? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

Brief introduction of protobuf

Protobuf is Google's open source serialization protocol framework, the structure is similar to XML,JSON, the remarkable feature is binary, high efficiency, mainly used in communication protocols and data storage and other aspects, is a structured data representation.

Advantages of protobuf

Everyone is using it, at least the pretending ones are using it [we have to keep up with the times]

Others say that the performance is good, and the binary format [shame on not using this for large projects]

Cross-platform support for a variety of languages, strong compatibility (after all, Google is using it)

Shortcomings of protobuf

Binary format, which most people can't read.

Lack of self-description

Xml is self-describing, but the protobuf format is not. Give you a binary file, and you can't see the effect.

Steps for using protobuf

Define your own data structure format (.pro) source file

Use the compiler provided by protobuf to compile the source file

Using api of protobuf go to read and write information

For example, define a structured data person that contains name and email attributes

As defined in xml

Zhangsan zhangsan@qq.com

Protobuf defines it this way.

Person {name: "zhangsan" email: "zhangsan@qq.com"}

As defined in json

{"person": {"name": "zhangsan", "email": "zhangsan@qq.com"}}

Syntax of protobuf

Message definition

A message type defines a request or corresponding message format, which can contain multiple types

Service service

If you need to use the message type on rpc, you need to define a rpc service interface in the .proto file, and the protocol buffer compiler generates the service interface code based on the language of your choice.

Protobuf is installed under ubuntu [version 16.04]

Official address: https://github.com/google/protobuf/blob/master/src/README.md

The installation command line is as follows:

$sudo apt-get install autoconf automake libtool curl make autogen.sh$ + unzip$ git clone https://github.com/google/protobuf.git$ cd protobuf$ git submodule update-- init-- recursive$. / autogen.sh$. / configure$ make$ make check$ sudo make install$ sudo ldconfig # refresh shared library cache.

Have a good trip to compile without any problems. Let's check the next version.

$protoc-version12
