linux C++项目使用jsonCPP库，项目不能编译。

faye_cb

项目采用JSONCPP处理JSON类型的数据，但是，项目编译是出现一下错误，哪位大侠linux 项目中采用了jsonCpp库，帮忙看看。

会不会缺少什么宏？

rain_fish

应该是路径什么的有问题吧

xwfang

请问这个问题解决了吗？

xwfang

这个问题 我们也遇到了 已经解决了   估计是因为 头文件的依赖顺序的问题 导致的

把 json 库 放在 /usr/local/include/ 目录下 然后
#include "json/json.h"

这样包含好像就可以编译通过

iCoolSea

回复下老帖，昨天晚上被整了好久，发现是json头文件和自己的头文件不能直接放一起，要把整个include目录下的json目录整体放到自己工程的include目录下

xsniper001

jsoncpp库在处理字符串数组的 时候会对数组重新排序，建议用cajun.我也是在一个项目中发现的这个问题，换的cajun

create2010

解决了没有？怎么解决的？

高逸民

我来给这个问题做个终结吧......将json/***.h整目录拷贝至/usr/local/include. 就可已解决这个错误了.具体的我也不清楚.

感谢5楼.五楼说的是对的.:wink:

fengidri

我发现 了问题在哪里了。


在jsoncpp的头文件中有一个features.h文件，这个文件在/usr/include下也有一个，我想应该是由于这个文件的冲突而形成 这个问题出现，如果在头文件引用 时通过json/...h的方式那么就不冲突也就是没有问题了

我想是这样的了
