cd JsonBox && make

示例程序：

#include <iostream>
#include <string>
#include "JsonBox/Value.h"
#include "JsonBox/Object.h"

int main(int argc, const char *argv[])
{
	JsonBox::Object o;
	o["value"] = JsonBox::Value(123);
	o["version"] = "v1.01";
	o["myOtherMember"] = JsonBox::Value("asld\\kfn");
	o["hahaha"] = JsonBox::Value(true);
	o["adamo"] = JsonBox::Value(129.09);
	std::cout << o << std::endl;

	JsonBox::Value v(o);

	std::cout << v["adamo"] << std::endl;
	return 0;
}

$ g++ demo.cpp -o demo -I ./JsonBox/include/  -L./JsonBox/build/ -lJsonBox

运行结果：

{
	"adamo" : 129.09,
	"hahaha" : true,
	"myOtherMember" : "asld\\kfn",
	"value" : 123,
	"version" : "v1.01"
}
129.09
