0. 依赖条件

本文采用centos系统编译libjson源码,先提前安装依赖。

#编译器
gcc, clang, or another C compiler
#cmake
cmake>=2.8, >=3.16 recommended
#若要生成文档,还需要doxygen
To generate docs you'll also need:
doxygen>=1.8.13

If you are on a relatively modern system, you'll likely be able to install the prerequisites using your OS's packaging system.

#Install using yum (e.g. CentOs 7.6)
$ yum install -y git
$ yum install -y cmake
$ yum install -y doxygen  # optional
$ yum install -y valgrind # optional

1. 下载源码

  官方Gibhub下载地址:https://github.com/json-c/json-c/releases

#git clone下载源码包并切换到指定release
$ git clone git@github.com:json-c/json-c.git
$ git checkout json-c-0.14-20200419

#或者直接下载tar包
$ wget https://github.com/json-c/json-c/archive/json-c-0.14-20200419.tar.gz -O json-c.tar.gz
$ tar zxvf json-c.tar.gz
$ mv json-c-json-c-0.14-20200419 json-c

2. 编译安装

#cmake构造自动化脚本
$ mkdir json-c-build && cd json-c-build
$ cmake ../json-c

然后执行编译安装

$ make
$ make test
$ make USE_VALGRIND=0 test   # optionally skip using valgrind
$ make install
