VBCC: size of incomplete type not available / linker

[Jose]

Hi. I'm getting "size of imcomplete type not avaible" with VBCC. WTF is that anyway?! I tryed to isolate the piece of code with that and it doesn't complain anaymore (bellow), go figure.
Also is there a big change in the latest VBCC so that you have to specify linking with amiga.lib ? If not then why does the bellow code get's an error with AllocMem in the linker? I tried it with -lamiga option but my A1200 crashed. I remember I had this problem in the past and forgot how I got over it, never bothered with that stuff, just rushed out coding:-D I'll try it again when I get home again...

Code: [Select]

#include <exec/memory.h>
#include <exec/types.h>
#include <stdio.h>
#include <stdlib.h>

#include <clib/exec_protos.h>

struct LONGSegment2Compare
{ LONG Offset;
  LONG *LONGsToCompare; /* Pointer to NULL terminated array of LONGs */
};

struct ConditionsToCheck
{ struct Node ConditionsToCheckNode;
  struct Conditions /* IMPORTANT: Bellow pointers to LONGSegment2Compare are pointers to a NULL terminated array */
  {  struct LONGSegment2Compare *AnyOfTheseFlagsMakesTrueIfTrue;
     struct LONGSegment2Compare *AnyOfTheseFlagsMakesTrueIfFalse;
     struct LONGSegment2Compare *TrueCombination;      struct LONGSegment2Compare *FalseCombination;
     struct Conditions *MutualExcl;
     struct MinConditions
     { struct LONGSegment2Compare *TrueCombination;
       struct LONGSegment2Compare *FalseCombination;
       struct Conditions *MutualExcl;
       struct MinConditions *Next;
     } *Next;
     struct Conditions *Terminal; /*Terminal points to the one that makes this forward linked list (through *Next) false */
  } Conditions;
  struct ActionSet **ActionSetPtrArray; /* Pointer to NULL terminated array of pointers to ActionSets to execute if this ConditionsToCheckList element is true*/
};

int main (int argc, char **argv)
{
 struct ConditionsToCheck Test;
 struct ConditionsToCheck *ConditionsToCheck = &Test;
 if (!(ConditionsToCheck->Conditions.TrueCombination = (struct LONGSegment2Compare *) AllocMem ((sizeof(struct LONGSegment2Compare)) * 2, MEMF_ANY)))
   printf (&quot;Something's wrong dude!!!&quot;);
 else
   printf (&quot;Way to go dude!!!&quot;);
 exit(0);
}

Hey 8-)

"You should increase the stack size to avoid crashes"
Done that, I discovered that my code got too big for a plain vanilla A1200, that´s the problem. It's more than 50K of source now.

"I don't get any incomplete type message from you code."

Yes, neither do I, I must have corrected the bug while trying to reproduce it, but I still can't find what's wrong in the original code :lol:

"In your code you probably used the wrong case. E.g. struct LONGSegment2compare instead of struct LONGSegment2Compare"

I tried to fix it again last night without any luck, I must be blind. I think I'm gonna wait till my A4000 is up and running again... Or maybe I'm gonna give WinUAE a try (not the ideal dev environment I know...)
The thing I don't understand is that my struct declaration posted here is copy/pasted from the original code, as well as the AllocMem line and I've checked everything and all names match. This is a weird one.

I'm too lazy to define external variables and put the includes in there again for every function, but it's got big so I must do it one of these days.

BTW isn't "make" a GCC thing only? I've only tried VBCC and SASC for now, but I guess every compiler can compile separate modules, problem is each one has different interface. In VBCC that seems to be easy though ( if using vc)
