json ubuntu下安装教程

1.首先安装scons

scons是linux下的自动构建工具，类似cmake。

下载地址
wget http://prdownloads.sourceforge.net/scons/scons-2.2.0.tar.gz

解压并安装之，如下

tar zxvf scons-2.2.0.tar.gz
cd scons-2.2.0
sudo python setup.py install

然后配置环境变量，sudo vi /etc/profile

\#json environment set
export MYSCONS=/home/gary/localization\_ws/json/scons-2.2.0
export SCONS\_LIB\_DIR=$MYSCONS/engine
export PATH=$MYSCONS:$SCONS\_LIB\_DIR:$PATH

退出后，执行source /etc/profile

jsoncpp的安装

先下载之http://sourceforge.net/projects/jsoncpp/files/

tar -zxf jsoncpp-src-0.5.0.tar.gz
cd jsoncpp-src-0.5.0
scons platform=linux-gcc

然后，将编译好的静态库和动态库文件拷贝考/usr/local/lib下

sudo cp libs/linux-gcc-5.4.0/libjson\_linux-gcc-5.4.0\_libmt.so /usr/local/lib/

sudo cp libs/linux-gcc-5.4.0/libjson\_linux-gcc-5.4.0\_libmt.a /usr/local/lib/
将头文件拷贝到/usr/local/include下面

sudo cp -r include/json/ /usr/local/include/

下面进行测试

#include <iostream>
#include <json/json.h>

using namespace std;

int main()
{
        Json::Value root;
        Json::FastWriter fast;
        root["DateTime"] = ("23");
        root["Name"] = ("hello");
        root["class"] = ("12");
        cout << fast.write(root) << endl;
        return 0;
}

编译之g++ test.cpp -o test /usr/local/lib/libjson\_linux-gcc-5.4.0\_libmt.a

执行./test

{"DateTime":"23","Name":"hello","class":"12"}

done!
