macros and size of

sizes.h:7:11: error: missing binary operator before token "("


the error above always occurs in this code and I don't know whats wrong..

Code:

---

#ifndef SIZES_H_
#define SIZES_H_

#include <stdlib.h>

/* Figure out how big your integers need to be */
#if(sizeof(long int) == 4)
typedef unsigned long int      int_u8;
typedef unsigned int            int_u4;
typedef unsigned short int      int_u2;
typedef unsigned char          int_u1;
typedef long int                int_8;
typedef int                    int_4;
typedef short int              int_2;
typedef char                    int_1;
#else
typedef unsigned long long int  int_u8;
typedef unsigned long int      int_u4;
typedef unsigned short int      int_u2;
typedef unsigned char          int_u1;
typedef long long int          int_8;
typedef long int                int_4;
typedef short int              int_2;
typedef char                    int_1;
#endif

#endif /* SIZES_H_ */

#if is evalueted by preprocessor
sizeof - by compiler... so you are trying to set a cart before the horse

hmm..so how can I do this?? I am trying to see if my machine is a 32 bit or not and assign the correct typedef ...

you should look for your project settings - for example my Win32 project settings include WIN32 define i can use in this #ifdef construct

I suppose the win64 configuration will include WIN64 define...

how do I check that?

In VS - go to Project/Properties/C++/Preprocessor/Preprocessor Definitions

In other IDEs It should be something similar

thanks
