MSVC中的错误？ [英] Bug in MSVC ?
问题描述
我无法在MSVC 2003或2005下编译以下代码。
..................... ............................. ..................... ....................
#include< stdio.h>
struct _MyStruct;
typedef struct _MyStruct MyStruct;
typedef void（* funcType）（MyStruct *）;
struct _MyStruct {double x;};
void MyFunc（MyStruct * theStruct）{printf（"％f"，theStruct-> x）;}
int main（）{
MyStruct A;
Ax = 100.0;
funcType f =& MyFunc;
f（& A）;
}
..................... ............................. ..................... .........
在gcc下，没问题。

从编译器中给我们一些错误。我看不到返回0在这里，但不要
知道你是忘了在这里写的还是只是片段。

你得到了什么编译错误？
我刚刚在MS VC ++ 2003上编译它并编译得很好。

我不确定是否返回是必要的主要，但我将它的
更好的形式加入。
以下是2003年的错误

know whether you forgot to write it here or is just the snippet.

I just compiled it on MS VC++ 2003 and it compiles fine.

I am not sure whether return is neccessary in main, but I aggree its
better form to put it in.
Here are the errors under 2003
.................................................. ............
------ Build started: Project: TestStruct, Configuration: Debug Win32
------
Compiling...

And under gcc 3.2.3 (mingw) not a peep, it compiles and works fine.
