2、安装先看README.txt
Protocol Buffers - Google's data interchange format
Copyright 2008 Google Inc.
http://code.google.com/apis/protocolbuffers/ C++ Installation - Unix
======================= To build and install the C++ Protocol Buffer runtime and the Protocol
Buffer compiler (protoc) execute the following: $ ./configure
$ make
$ make check
$ make install If "make check" fails, you can still install, but it is likely that
some features of this library will not work correctly on your system.
Proceed at your own risk. "make install" may require superuser privileges. For advanced usage information on configure and make, see INSTALL.txt. ** Hint on install location ** By default, the package will be installed to /usr/local. However,
on many platforms, /usr/local/lib is not part of LD_LIBRARY_PATH.
You can add it, but it may be easier to just install to /usr
instead. To do this, invoke configure as follows: ./configure --prefix=/usr If you already built the package with a different prefix, make sure
to run "make clean" before building again. ** Compiling dependent packages ** To compile a package that uses Protocol Buffers, you need to pass
various flags to your compiler and linker. As of version 2.2.0,
Protocol Buffers integrates with pkg-config to manage this. If you
have pkg-config installed, then you can invoke it to get a list of
flags like so: pkg-config --cflags protobuf # print compiler flags
pkg-config --libs protobuf # print linker flags
pkg-config --cflags --libs protobuf # print both For example: c++ my_program.cc my_proto.pb.cc `pkg-config --cflags --libs protobuf` Note that packages written prior to the 2.2.0 release of Protocol
Buffers may not yet integrate with pkg-config to get flags, and may
not pass the correct set of flags to correctly link against
libprotobuf. If the package in question uses autoconf, you can
often fix the problem by invoking its configure script like: configure CXXFLAGS="$(pkg-config --cflags protobuf)" \
LIBS="$(pkg-config --libs protobuf)" This will force it to use the correct flags. If you are writing an autoconf-based package that uses Protocol
Buffers, you should probably use the PKG_CHECK_MODULES macro in your
configure script like: PKG_CHECK_MODULES([protobuf], [protobuf]) See the pkg-config man page for more info. If you only want protobuf-lite, substitute "protobuf-lite" in place
of "protobuf" in these examples. ** Note for cross-compiling ** The makefiles normally invoke the protoc executable that they just
built in order to build tests. When cross-compiling, the protoc
executable may not be executable on the host machine. In this case,
you must build a copy of protoc for the host machine first, then use
the --with-protoc option to tell configure to use it instead. For
example: ./configure --with-protoc=protoc This will use the installed protoc (found in your $PATH) instead of
trying to execute the one built during the build process. You can
also use an executable that hasn't been installed. For example, if
you built the protobuf package for your host machine in ../host,
you might do: ./configure --with-protoc=../host/src/protoc Either way, you must make sure that the protoc executable you use
has the same version as the protobuf source code you are trying to
use it with. ** Note for Solaris users ** Solaris 10 x86 has a bug that will make linking fail, complaining
about libstdc++.la being invalid. We have included a work-around
in this package. To use the work-around, run configure as follows: ./configure LDFLAGS=-L$PWD/src/solaris See src/solaris/libstdc++.la for more info on this bug. ** Note for HP C++ Tru64 users ** To compile invoke configure as follows: ./configure CXXFLAGS="-O -std ansi -ieee -D__USE_STD_IOSTREAM" Also, you will need to use gmake instead of make. C++ Installation - Windows
========================== If you are using Microsoft Visual C++, see vsprojects/readme.txt. If you are using Cygwin or MinGW, follow the Unix installation
instructions, above. Binary Compatibility Warning
============================ Due to the nature of C++, it is unlikely that any two versions of the
Protocol Buffers C++ runtime libraries will have compatible ABIs.
That is, if you linked an executable against an older version of
libprotobuf, it is unlikely to work with a newer version without
re-compiling. This problem, when it occurs, will normally be detected
immediately on startup of your app. Still, you may want to consider
using static linkage. You can configure this package to install
static libraries only using: ./configure --disable-shared Java and Python Installation
============================ The Java and Python runtime libraries for Protocol Buffers are located
in the java and python directories. See the README file in each
directory for more information on how to compile and install them.
Note that both of them require you to first install the Protocol
Buffer compiler (protoc), which is part of the C++ package. Usage
===== The complete documentation for Protocol Buffers is available via the
web at: http://code.google.com/apis/protocolbuffers/
3、确认安装过GCC:终端下输入gcc - -version 测试
4、终端切换管理员:sudo su,输入密码后如果看到sh-3.2#,表明成功。
5、终端下切换到protobuf。cd protobuf-2.5.0
6、在终端输入. / configure。注:或者输入:./configure - -prefix=$INSTALL_DIR
7、输入
$ make
$ make check
$ make install
输入protoc - - version检查是否安装成功。
8、添加到路径:./configure --prefix=/usr
9、通过上面的步奏,基本可以了,如果不可以,可以继续做README.txt其他步奏,里面都有教程,只不过是英文版而已。
10、编译代码,把msg.proto放在protobuf-2.5.0下的exmaples文件夹下,终端进去cd protobuf-2.5.0:
(1)、编译为java: protoc --java_out=./examples ./examples/msg.proto
(2)、编译为c++: protoc --cpp_out=./examples ./examples/msg.proto
(3)、编译为python: protoc --python_out=./examples ./examples/msg.proto
11、附上msg.proto文件:
option java_package = "com.protobuftest.protobuf";
option java_outer_classname = "PersonProbuf"; message Person {
required string name = 1;
required int32 id = 2;
optional string email = 3; enum PhoneType {
MOBILE = 0;
HOME = 1;
WORK = 2;
} message PhoneNumber {
required string number = 1;
optional PhoneType type = 2 [default = HOME];
} repeated PhoneNumber phone = 4; message CountryInfo {
required string name = 1;
required string code = 2;
optional int32 number = 3;
}
} message AddressBook {
repeated Person person = 1;
}
其他:
1、官方例子可以查看examples文件夹。
2、查看官方例子说明:https://developers.google.com/protocol-buffers/docs/javatutorial
官网小例子如生成一个Person对象
Person john =
Person.newBuilder()
.setId(1234)
.setName("John Doe")
.setEmail("jdoe@example.com")
.addPhone(
Person.PhoneNumber.newBuilder()
.setNumber("555-4321")
.setType(Person.PhoneType.HOME))
.build();
