在openSUSE下编译QtProject时出错

我试着在openSUSE下使用CMAKE编译我的项目来生成makefile。在openSUSE下编译QtProject时出错

现在，我得到了这个错误。有人可以帮助我吗？

马丁，请你可以显示错误代码？看来你正在调用你不能的功能 – RGarcia

要调用这些函数：* qVersion（）; qTerminate（）; qt_error_string（）;等等。

看来你是不是在正确的地方打电话给他们（预期的构造函数，析构函数或类型转换之前“（”），必须在函数中声明：

bool someclass() 
{ 
qSharedBuild(); --bool type 
return false; 
}

我挖成的CMakeLists.txt想通了，一个colluege增加了-DWIN64到编译器标志。

Qt是知道的以为它是Windows下的编译和就将此“Q_OS_WIN”定义

现在Q_CORE_EXPORT正在寻找__declspec宏...
