I''ve been working with DX8 and I''m getting stupid linker errors. I don''t mind bugs, but I hate bugs related to linking. Here''s my problem, if anyone has a suggestion it would be greatly appreciated: I have a header file: #ifndef VERTEX_H #define VERTEX_H typedef struct vertex_s { float x,y,z; DWORD color; float tu,tv; } vertex; vertex *vertices; WORD *indices; #endif And one file has a #include "vertex.h", everything compiles fine. But if i have another file in my project that also includes vertex.h I get the following errors: fractal.cpp d:\4080\fract_ter\vertex.h(7) : error C2146: syntax error : missing '';'' before identifier ''color'' d:\4080\fract_ter\vertex.h(7) : error C2501: ''DWORD'' : missing storage-class or type specifiers d:\4080\fract_ter\vertex.h(7) : error C2501: ''color'' : missing storage-class or type specifiers d:\4080\fract_ter\vertex.h(13) : error C2143: syntax error : missing '';'' before ''*'' d:\4080\fract_ter\vertex.h(13) : error C2501: ''WORD'' : missing storage-class or type specifiers d:\4080\fract_ter\vertex.h(13) : error C2501: ''indices'' : missing storage-class or type specifiers anyone have any suggestions? Thanks in advance.

vertex *vertices;
WORD *indices;

You should never declare variables in header files -- this will cause some conflicts. Just declare them in a CPP file, and write

extern vertex *vertices;
extern WORD *indices;

in your header file -- that will make it possible for everyone to access the variables...

... but I don''t think that''s the only problem.

Have you included windows.h in your sources before using DWORD, WORD, and so on?

I think it''s because the compiler doesn''t know what a DWORD is. And as far as I know, DWORD is defined somewhere in the windows header files. Try including <windows.h> in your header file.

And yes, don''t declare variables in your header files, except if you''re looking for trouble . Better to declare them external in the header, and declare them for real in some source file, like kadaf said.
