Protobuf源码下载：

https://github.com/JumpWu/xls2protobuf/tree/master/protobuf-V3.0

1、切换到protobuf-V3.0 根目录，运行. autogen.sh前，我们需要先安装autoconf automake libtool

2、autoconf 安装

curl -OL http://ftpmirror.gnu.org/autoconf/autoconf-2.69.tar.gz
tar -xzf autoconf-2.69.tar.gz 
cd autoconf-2.69
./configure && make && sudo make install

3、automake 安装

curl -OL http://ftpmirror.gnu.org/automake/automake-1.14.tar.gz
tar -xzf automake-1.14.tar.gz
cd automake-1.14
./configure && make && sudo make install

4、libtool安装

curl -OL http://ftpmirror.gnu.org/libtool/libtool-2.4.2.tar.gz
tar -xzf libtool-2.4.2.tar.gz
cd libtool-2.4.2
./configure && make && sudo make install

5、protoc编译安装

./configure
make
make check
sudo make install

6、编译.proto
proto文件存放目录$SRC_DIR

 protoc -I=$SRC_DIR --cpp_out=$DST_DIR $SRC_DIR/test.proto

命令查看：protoc －help
Usage: protoc [OPTION] PROTO_FILES
Parse PROTO_FILES and generate output based on the options given:
  -IPATH, --proto_path=PATH   Specify the directory in which to search for
                              imports.  May be specified multiple times;
                              directories will be searched in order.  If not
                              given, the current working directory is used.
  --version                   Show version info and exit.
  -h, --help                  Show this text and exit.
  --encode=MESSAGE_TYPE       Read a text-format message of the given type
                              from standard input and write it in binary
                              to standard output.  The message type must
                              be defined in PROTO_FILES or their imports.
  --decode=MESSAGE_TYPE       Read a binary message of the given type from
                              standard input and write it in text format
                              to standard output.  The message type must
                              be defined in PROTO_FILES or their imports.
  --decode_raw                Read an arbitrary protocol message from
                              standard input and write the raw tag/value
                              pairs in text format to standard output.  No
                              PROTO_FILES should be given when using this
                              flag.
  -oFILE,                     Writes a FileDescriptorSet (a protocol buffer,
    --descriptor_set_out=FILE defined in descriptor.proto) containing all of
                              the input files to FILE.
  --include_imports           When using --descriptor_set_out, also include
                              all dependencies of the input files in the
                              set, so that the set is self-contained.
  --include_source_info       When using --descriptor_set_out, do not strip
                              SourceCodeInfo from the FileDescriptorProto.
                              This results in vastly larger descriptors that
                              include information about the original
                              location of each decl in the source file as
                              well as surrounding comments.
  --dependency_out=FILE       Write a dependency output file in the format
                              expected by make. This writes the transitive
                              set of input file paths to FILE
  --error_format=FORMAT       Set the format in which to print errors.
                              FORMAT may be 'gcc' (the default) or 'msvs'
                              (Microsoft Visual Studio format).
  --print_free_field_numbers  Print the free field numbers of the messages
                              defined in the given proto files. Groups share
                              the same field number space with the parent 
                              message. Extension ranges are counted as 
                              occupied fields numbers.
  --plugin=EXECUTABLE         Specifies a plugin executable to use.
                              Normally, protoc searches the PATH for
                              plugins, but you may specify additional
                              executables not in the path using this flag.
                              Additionally, EXECUTABLE may be of the form
                              NAME=PATH, in which case the given plugin name
                              is mapped to the given executable even if
                              the executable's own name differs.
  --cpp_out=OUT_DIR           Generate C++ header and source.
  --csharp_out=OUT_DIR        Generate C# source file.
  --java_out=OUT_DIR          Generate Java source file.
  --javanano_out=OUT_DIR      Generate Java Nano source file.
  --objc_out=OUT_DIR          Generate Objective C header and source.
  --python_out=OUT_DIR        Generate Python source file.
  --ruby_out=OUT_DIR          Generate Ruby source file.
