Today, the editor will share with you the relevant knowledge points about how to install and configure Jsoncpp under CentOS. The content is detailed and the logic is clear. I believe most people still know too much about this knowledge, so share this article for your reference. I hope you can get something after reading this article.

1. Installation

Execute a command

[root@VM-0-9-centos ~] # cd / home [root @ VM-0-9-centos home] # mkdir jsoncp [root @ VM-0-9-centos home] # cd jsoncpp/ [root @ VM-0-9-centos jsoncpp] # wget https://github.com/open-source-parsers/jsoncpp/archive/1.9.4.zip[root@VM-0-9-centos jsoncpp] # unzip 1.9.4.zip [root @ VM-0-9-centos jsoncpp] # Cd jsoncpp-1.9.4/ [root@VM-0-9-centos jsoncpp-1.9.4] # cmake. [root@VM-0-9-centos jsoncpp-1.9.4] # make[ root @ VM-0-9-centos jsoncpp-1.9.4] # make install2. test

Create a test folder and two files

[root@VM-0-9-centos jsoncpp-1.9.4] # mkdir Xltest [root @ VM-0-9-centos jsoncpp-1.9.4] # cd Xltest [root @ VM-0-9-centos xltest] # vim jsontest.json [root @ VM-0-9-centos xltest] # vim jsontest.cpp

The jsontest.json is as follows

[{"name": "Long", "age": 6}]

Jsontest.cpp is as follows

# include # include using namespace std;int main (void) {ifstream ifs; ifs.open ("jsontest.json"); assert (ifs.is_open ()); Json::Reader reader; Json::Value root; if (! reader.parse (ifs, root, false)) {cout
