无法typedef结构 [英] Can't typedef a struct
问题描述
我在一个.h文件中有这个，我把它包含在.cpp文件中：
typedef struct {
double x;
双倍;
} pointz;
但是当我编译时我得到：
图形/debug.h：13：错误：冲突声明？typedef struct
pointz pointz？
graphics / debug.h:13:error:?pointz？有一个先前的声明为
？typedef struct pointz pointz？
但我之前没有声明''积分''。
I have this in a .h file which I include in a .cpp file:
typedef struct {
double x;
double y;
} pointz;
But when I compile I get:
graphics/debug.h:13: error: conflicting declaration ?typedef struct
pointz pointz?
graphics/debug.h:13: error: ?pointz? has a previous declaration as
?typedef struct pointz pointz?
But I have not previously declared ''points''.

在C ++中，不要使用typedef。
struct pointz
{
双倍x;
双倍;
};

In C++, don''t use typedef.
struct pointz
{
double x;
double y;
};

In C ++，不要使用typedef。
struct pointz
{
double x;
双y;
};
In C++, don''t use typedef.
struct pointz
{
double x;
double y;
};
此外，你可能想要包括这两次而不包括
警卫。
In addition, it may be you are tying to include this twice without include
guards.

在C ++中，不要使用typedef。
struct pointz
{
双x;
双y;
};
In C++, don''t use typedef.
struct pointz
{
double x;
double y;
};
with
struct pointz {
double x;
double y;
};
然后我得到：
graphics / debug.h:10：错误：重新定义？struct pointz？
graphics / debug.h： 10：错误：以前定义的？struct pointz？
即使之前没有声明过。
with
struct pointz {
double x;
double y;
};
Then I just get:
graphics/debug.h:10: error: redefinition of ?struct pointz?
graphics/debug.h:10: error: previous definition of ?struct pointz?
even though its not been declared before.
