Compile error in 'winbase.h'

Question

I get the following error with a Windows file when compiling winbase.h.

Not sure why I get a syntax error and the compiler shows many more:

1> c:\program files\microsoft sdks\windows\v6.0a\include\winbase.h(238) :     error C2146: syntax error : missing ';' before identifier 'Internal' 

Here a simple code to reproduce the problem:

#include <winbase.h>  int main() {     return 0; } 

Answer 1

Are you including <winbase.h> directly?

You shouldn't - it expects to have some things defined/declared before it's processed. Specifically in this case the identifier ULONG_PTR which is declared as a typedef in intsafe.h.

Include <windows.h>.

Answer 2

You are probably missing a ; immediate before the #include <windows.h> line in your code. Alternatively, there is some identifier-like text preceding the include file line.

int ABC #include <windows.h>
