linux中yaml安装包如何安装,yaml-cpp的安装

C++下有这一个Yaml的解析包,PHP也有一个Yaml的解析包,这样两者就能进行对文件的解析是一个规则,达到统一的目的,双方就可以通讯,这样语言之间对配置的解析一样,上层通过Socket来通信统一,进而实现大系统的搭建。

首先要有CMake环境,需要编译一个CMake出来,然后才是在下载下来的文件目录下运行这个Cmake:

tar -zxvf cmake-2.8.4.tar.gz

首先,需要下载安装Cmake;

wget http://www.cmake.org/files/v2.8/cmake-2.8.4.tar.gz

安装cmake;

tar xvzf cmake-2.8.4.tar.gz

./configure

make

make install

其次,下载YAML的C++解析器 yaml-cpp ,URL为:http://www.oschina.NET/p/yaml-cpp                                                                                      https://github.com/jbeder/yaml-cpp/releases/

编译:

cmake  -DBUILD_SHARED_LIBS=ON

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp# cmake  -DBUILD_SHARED_LIBS=ON

然后呢: make ,后生成:

/home/admin/c++/yaml_4_C/yaml-cpp/test3

libyaml-cpp.so.0.2.6

libyaml-cpp.so.0.2 -> libyaml-cpp.so.0.2.6

libyaml-cpp.so -> libyaml-cpp.so.0.2

查看H文件位置:

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp# find . -name "yaml.h"

./include/yaml-cpp/yaml.h

最后,进行Yaml的代码解析测试:

1)建立目录:

mkdir test3

目录位置:[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3

2)写入C++测试代码

1.vi test.cpp

加入:

#include

#include "yaml.h"

int main()

{

std::ifstream fin("component.yaml");

YAML::Parser parser(fin);

YAML::Node doc;

while(parser.GetNextDocument(doc))

{

}

}

3).把yaml.h拷贝到test3的目录下来:

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3# cp ../include/yaml-cpp/yaml.h

4)后进行编译编译:

g++ -o test test.cpp -I../include/ ../libyaml-cpp.so

5)运行测试

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3# ./test

./test: error while loading shared libraries: libyaml-cpp.so.0.2: cannot open shared object file: No such file or directory

6)解决问题:

/home/admin/c++/yaml_4_C/yaml-cpp/test3

libyaml-cpp.so.0.2.6

libyaml-cpp.so.0.2 -> libyaml-cpp.so.0.2.6

libyaml-cpp.so -> libyaml-cpp.so.0.2

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp# cp libyaml-cpp.so  /usr/lib/

[email protected]:/usr/lib# ln -s libyaml-cpp.so libyaml-cpp.so.0.2

7)再次执行,得到解决:

再执行就不报错了,原来是没有把这个so给放到/usr/lib下,再就是没有给重新软链接一个,Ok了。

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3# ./test

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3#

8)自由发挥,放到实际的开发中去。

Yaml实际解析测试:

#include

#include "yaml.h"

#include

#include

using namespace std;

int main()

{

std::ifstream fin("component.yaml");

YAML::Parser parser(fin);

YAML::Node doc;

while(parser.GetNextDocument(doc))

{

std::string output;

doc["site"] >> output;

cout << output <

}

}

component.yaml这个Yaml文件的内容:

site: jackxiang.com

编译:

g++ -g -o test test.cpp -I../include/ ../libyaml-cpp.so

测试Yaml解析是否成功:

[email protected]:/home/admin/c++/yaml_4_C/yaml-cpp/test3# ./test

jackxiang.com

解析成功!

最后,当然还有纯C语言的,来解析 YAML 1.1 数据,其编译估计差不多,下载URl:

http://www.oschina.net/p/libyaml

建议用eclipse来开发C++,还有PHP,因为eclipse 有PHP的插件,也有C++的插件,我是用的Zend for eclipse,现在eclipse还有一个Yaml的编辑插件,相关介绍情况如下:

安装YEdit

YEdit是一个在Eclipse上编辑YAML文件的插件。当我们我们使用Python进行App Engine的开发,会涉及编辑一些YAML文件,这个插件提供了较好的支持。

这个还是通过Eclipse的更新管理器来完成安装,在对话框中的在Work with中输入http://dadacoalition.org/yedit,然后勾选该插件,然后不断下一步,稍等片刻,安装成功。
