我尝试使用CMAKE在openSUSE下编译我的项目来生成makefile。
现在,我收到了这个错误。有人可以帮助我吗?

您正在调用这些函数:* qVersion(); qTerminate(); qt_error_string();等等。
似乎你没有在正确的位置调用它们(预期的构造函数,析构函数或者在'('之前)的类型转换,必须在函数内部声明:
bool someclass()
{
qSharedBuild(); --bool type
return false;
}

我深入研究了CMakeLists.txt,并发现,一个colluege已将-DWIN64添加到编译器标志中。
Qt知道它正在Windows下编译并加入“Q_OS_WIN”定义
现在Q_CORE_EXPORT正在寻找__declspec宏......
