Question

I’m getting the following:

Unknown type name 'mach_port_context_t'

As a compiler error when I’m trying to build my XCode project. It points to message.h, which is in the iPhoneSimulator5.1/usr/include/mach/ folder.

It doesn’t show up when I build for the device. (I’m testing in simulator b/c I need to debug some files)
I’m definitely not doing any crazy threading or port stuff (outside of NSOperation), so I’m not sure what the issue for the mach is…

mach_port_context_t has no definition in message.h file… others such as audit_token_t and security_token_t do:

typedef struct 
{
  mach_msg_trailer_type_t   msgh_trailer_type;
  mach_msg_trailer_size_t   msgh_trailer_size;
  mach_port_seqno_t     msgh_seqno;
  security_token_t      msgh_sender; // <-- defined (ex. below)
  audit_token_t         msgh_audit; //<-- defined (ex. below)
  mach_port_context_t       msgh_context; //<-- Error Here
} mach_msg_context_trailer_t;

typedef struct
{
  unsigned int          val[8];
} audit_token_t;

typedef struct
{
  unsigned int          val[2];
} security_token_t;

Help?
