error: 'something' does not name a type

[mahmoodn]

Hi,
I have a struct with this definition

struct SeverityAction : public Action {
    uint32_t theSeverity;      //*****
  public:
    SeverityAction(uint32_t aSeverity);
...
};
 

and the uint32_t is defined in "/usr/include/stdint.h"

/* Unsigned.  */
typedef unsigned char        uint8_t;
typedef unsigned short int    uint16_t;
#ifndef __uint32_t_defined
typedef unsigned int        uint32_t;
# define __uint32_t_defined
#endif
#if __WORDSIZE == 64
typedef unsigned long int    uint64_t;
#else
__extension__
typedef unsigned long long int    uint64_t;
#endif

However I get this error:

error: ‘uint32_t’ does not name a type
error: expected ‘)’ before ‘aSeverity’

How can I fix that?

uint32_t might be defined in "/usr/include/stdint.h" but have you included it in a relevant place?

[mahmoodn]

You are right. that file was included in another file but previous versions of gcc didn't complain about that.

thanks :)

If you need a header you should include it.

You should not assume that just because it is included into another header that you include that in future versions that other header will continue to include the header you need.
