Compilation and use of Protobuf on Ubuntu 14

Objective

Always know that Google Open source of a language-independent data exchange protocol: PROTOBUF. Just know that it's a different format than JSON and XML, and that's especially good for performance (this is true for Java and C + + implementations!). ）

Recently idle down to see Google's protobuf related things, but Baidu out of a lot of things are outdated, I have to spend some time to Daoteng, so there is the following content.

• Download source code and preparation work

$ sudo apt-get install autoconf automake Libtool Curl
$ git clone https://

• Modify Autogen.sh

Because of the "you Know" reason, Autogen can't curl download to Gmock's source code package, so I put Gmock's package on my own github. Modify the autogen.sh and let it download the package on my GitHub

#把curl那一行替换成绿色的

• Generate Configure File

$ ./autogen

• Compiling and installing PROTOBUF

$./make makesudomakeinstall   sudo ldconfig # refresh shared library cache.

Note: The default is installed under "/usr/local/lib", on some platforms/usr/local/lib is not the default Ld_library_path variable, you can change the installation directory by the following command

$./configure--PREFIX=/USR

When you see a text similar to the following, the PROTOBUF Basic installation is complete

============================================================================testsuite Summary for Protocol Buffers 3.0.0-beta-2============================================================================6  # PASS:  6# SKIP:  00# FAIL:   0  00=========================================================== =================

The next step is to configure some of the Python language-related

• Python support for installing PROTOBUF

CD python # located under Protobuf
sudoinstall

Note: If the above command fails, you can try to install the next PIP related package, can solve some Python package dependency problem

sudo Install Python-pip

The next step is to use PROTOBUF.

• Compiling the. Proto file

Touch1   String 2 string 1 string 2 ;}

• Generate a PY file for use in later Python

Protoc--python_out=. ./dataservice.proto

• Use of Protobuf

Create a testdataservice.py file and put it in the following section

ImportSYSImportDATASERVICE_PB2#Create Protorow =DATASERVICE_PB2. Rowproto () Row.null_map= 1Row.column.append ("Wang") Row.column.append ("female") Row_str=row. Serializetostring ()Print"Row_str:", row_strtable=DATASERVICE_PB2. Tableproto () table.column.append ("name") Table.column.append ("Gender") table.row.append (row_str) table_str=table. Serializetostring ()#process ProtoTable_proto =DATASERVICE_PB2. Tableproto () Table_proto. Parsefromstring (TABLE_STR)Print "column:"PrintTable_proto.columnrow_str=Table_proto.row[0]row_proto=DATASERVICE_PB2. Rowproto () Row_proto. Parsefromstring (Row_str.encode ('UTF8'))Print "Row1:"PrintRow_proto.column

Run testdataserver.py

[Email protected]:~/protobuf/proto_test$ python testdataservice.pyrow_str:wangfemalecolumn:[u' name ', u'gender']row1:[u'Wang', u ' female ']

The content of this issue is this, mainly PROTOBUF installation and configuration, the use of less involved, there will be time to add more use related content

FAQ:

If you encounter:

 while loading shared libraries:libprotoc.so. Ten Object file file or directory

Solution Solutions

sudo ldconfig
