程序突然飙出685个错误
网上查了半天也没搞懂，有没有大神救救我！第二次用qt做程序的小朋友求助！

可以告诉我大概是什么类型的错误吗？我的程序代码有点多，然后窗口有7个，一下子放上来太多了。

他显示是qmetatype.h 和 qnamespace.h 这两个头文件里有错误

这种情况下你查看一下头文件是否正确。把math.h文件贴出来看看

主要看一看 mainwindow.h 文件。

C/C++编程：/usr/include/wchar.h:75:43: error: missing binary operator before token “(“
最近编译代码， 引入json库， 结果编译的时候， 莫名其妙出现： /usr/include/wchar.h:75:43: error: missing binary operator before token "(" ，接着就是一大堆错误， 我是这么解决的： 1. 改#include "json.h"为 #include "json/json.h" 2. 改makefile的 /xxxx/xxxx/xxxx/comm/json为/xxxx/xxxx/xxxx/comm/...
