Function pointer in a structure makes a compiler mess-SOLVED
PostPosted: Sun Dec 13, 2015 11:58 am     Reply with quote

Hi,

Compiler 5.025

This is unacceptable:

Code:
struct process
{
   unsigned char* name;
   int (*func)(void);
   int8 called;
   struct process* p_process;
}process_riko;


When I remove int (*func)(void); everything works.

try typedef'ing the function pointer type first:

Code:

typedef int (*func_type)(void);

struct process
{
   unsigned char* name;
   func_type func;
   int8 called;
   struct process* p_process;
}process_riko;


Also keep in mind, I think there was a version 5 change somewhere that corrected how function pointers worked. I don't remember how far back that was though.

In addition to the typedefing, your version of the compiler also has the
bug listed in this thread:
http://www.ccsinfo.com/forum/viewtopic.php?t=54461
Which can be fixed like this:
Code:

typedef int (*func_type)(void);

struct process
{
   unsigned char* name;
   func_type func;
   int16 dummy;     // *** Added to fix bug in link
   int8 called;
   struct process* p_process;
}process_riko;
 


This bug was fixed in compiler vs. 5.051.

Thank you guys. It works with typedef. I hope CCS will fix that problem in the future versions.

Make sure to email them a bug report so they will hopefully be able to fix that.
