Thread: Compiler thinks I'm defining when I'm trying to call

I'm trying to create a DX sprite...

Code:

LPD3DXSPRITE d3dspt;
LPDIRECT3DTEXTURE9 sprite;
	
D3DXCreateSprite(d3ddev, &d3dspt);
D3DXCreateTextureFromFile(d3ddev, L"panel1.png", &sprite);

...and I'm getting this...

Code:

render.cpp(25) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
render.cpp(25) : error C2365: 'D3DXCreateSprite' : redefinition; previous definition was 'function'

are you doing this inside a function?

All code (statements which do something at runtime) must be located inside a function.

Having statements at global scope is not possible, because C and C++ programs can be composed of multiple modules. Suppose two modules A.cpp and B.cpp both have code at the global scope. When these two modules are compiled and linked together, which code should execute first -- the statements from A.cpp or the ones from B.cpp?

Because this question has no clear answer, code statements are not allowed at the global scope.

In C++, where it is possible to declare global objects which have constructors, this problem actually still exists. It's not defined what order global objects from different modules will be constructed, and this leads to problems in practice.
