Sorry, but I was not very clear in my last post. I would like to ask my question again if you don't mind: How can I create a std::vector and put data in it of a type I created with 'typedef struct'? [Edited by - MarauderX on August 1, 2006 3:49:24 PM]

struct MyStruct{  ... Some data ...};std::vector< MyStruct > myVector;

If I do that I get the following error, wich I don't understand:

CCameras.cppC:\Program Files\Microsoft Visual Studio 8\VC\include\vector(694) : error C2719: '_Val': formal parameter with __declspec(align('16')) won't be aligned        D:\CodenameM\CCameras.h(16) : see reference to class template instantiation 'std::vector<_Ty>' being compiled        with        [            _Ty=STRUCT_CAMERA        ]

this is my code:

#include <d3dx9.h>#include <vector>struct STRUCT_CAMERA{    // some data} ;class CCameras{private:	std::vector< STRUCT_CAMERA > cams;	public:    CCameras();    ~CCameras();};

That compiles fine for me.

You have failed to provide adequate information. Post all of your code, don't omit things -- those may very be the things that are important.

In this case, I suspect that "// some data..." includes at least one object such as D3DXMATRIXA16, which is declared with the __declspec(align(16)) keyword. This causes the error, not the use of "typedef struct" (which I maintain you should avoid -- this is C++, where it is unneccessary and ugly). The alignment cannot be maintained, so the object cannot be stored.

Don't use structures requiring alignment, or write your own allocator.
