json库安装问题？（不知的安装那个库）
网上下的isac-menu.cpp，编译需要json库，但不知到用那个？错误如下：

求高人指点啊。需要使用那个库？ json-c是你不二的选择. 回复 3# linux_c_py_php
我们在网上下的源码，想添加到我们程序中，是c++的，里面由JSONOBJECT, JSONVALUE, JSONARRAY等，如何确定是使用的那一个json库啊（源码中未说明）？
如果使用其他的库，那需要改的就太多了。 本帖最后由 lifuhua666666 于 2012-11-14 19:34 编辑
最终我使用jsoncpp库，添加定义如下：
typedef Json::Value JSONOBJECT;
typedef Json::Value JSONVALUE;
typedef Json::Value JSONARRAY;
并少量修改源码，可以满足需求。
