GCC Compiler Warning: extended initializer lists only available with c++0x
提问by Anonymous
Using this member initialization...
使用这个成员初始化...
StatsScreen::StatsScreen( GameState::State level )
: m_Level( level ) {
...//
}
I get the following warning...
我收到以下警告...
extended initializer lists only available with -std=c++0x or -std=gnu++0x
extended initializer lists only available with -std=c++0x or -std=gnu++0x
Any information regarding this warning?
有关此警告的任何信息？
Edit: Warning went away after I removed one of the member that was assigned to a value inside the constructor (couldn't be done through member initialization) and made it a local variable instead of a class member. Still want to know what that warnings means though.
编辑：在我删除了分配给构造函数内部值的成员之一（无法通过成员初始化完成）并将其设为局部变量而不是类成员后，警告消失了。仍然想知道这些警告是什么意思。

I think you are initializing the object with {...}instead of (...):
我认为您正在使用{...}而不是初始化对象(...)：
StatsScreen ss{...}; // only available in C++0x
StatsScreen ss(...); // OK in C++98
To compile your code as C++0x code, just add the following flag when compiling:
要将您的代码编译为 C++0x 代码，只需在编译时添加以下标志：
g++ test.cpp -std=c++0x
