编写测试

main.cpp

#include <cstdio>
#include <cstring>
#include <string>
#include <iostream>

#include "json/json.h" 

@H_502_23@using @H_502_23@namespace std;

@H_502_23@int main()
{
    string test ="{\"id\":1,\"name\":\"kurama\"}";
    Json::Reader reader;
    Json::Value value;
    @H_502_23@if(reader.parse(test,value))
    {
      @H_502_23@if(!value["id"].isNull())
      {
        cout<<value["id"].asInt()<<endl;
        cout<<value["name"].asString()<<endl;
      }
    }

    @H_502_23@return 0;
}

CMakeLists.txt

@H_502_23@PROJECT (FUN)

@H_502_23@set(APP_SRC main.cpp)
@H_502_23@set(exe_name test)
@H_502_23@set(lib_name json_linux-gcc-5.4.0_libmt)

# 库头文件所在目录
@H_502_23@set(lib_inc /home/ding/Downloads/jsoncpp-src-0.5.0/@H_502_23@include CACHE PATH "include of ")
# 库文件所在目录
@H_502_23@set(lib_dir /home/ding/Downloads/jsoncpp-src-0.5.0/libs/linux-gcc-5.4.0 CACHE PATH "directory of .lib")

# 在这里动态库与静态库的设置是一样的
# 指定头文件的搜索路径
@H_502_23@include_directories(${lib_inc})
# 指定库文件的搜索路径
@H_502_23@link_directories(${lib_dir})

# 可执行文件生成在 ./bin下面
@H_502_23@set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)

# 生成可执行文件
@H_502_23@add_executable(${exe_name} ${APP_SRC})

# 可执行文件 需要链接 库
@H_502_23@target_link_libraries(${exe_name} ${lib_name})

运行脚本travis.sh

#!/usr/bin/env sh
#set -evx
#env | sort

EXE_DIR=./bin
BUILD_DIR=./build

@H_502_23@if [ ! -d ${EXE_DIR} ] 
@H_502_23@then
    mkdir ${EXE_DIR}
@H_502_23@else
#echo "aaa"
    rm -rf ${EXE_DIR}/* 
@H_502_23@fi

@H_502_23@if [ ! -d ${BUILD_DIR} ]
@H_502_23@then 
    mkdir ${BUILD_DIR} 
@H_502_23@else
#echo "ccc"
    rm -rf ${BUILD_DIR}/*
@H_502_23@fi

cd build
cmake ..
make
