azone2 question

[Harcourt]

Thanks for the responses. I am building on 64-bit Linux. I rebuilt azone2 as a 32-bit application and it runs fine.

And most importantly, the mobs in Moors follow the terrain now.

For any Fedora folks out there, you'll need:
zlib-devel-1.2.5-6.fc16.i686

I looked into building a working 64-bit version. There is some sort of sizing error, as the following is 20 bytes long rather than 12. Probably alignment.

struct struct_header {
  unsigned long offset;
  char magicCookie[4];
  unsigned long unknown;
} typedef struct_header;

PS: Reading the structure field-by-field may be the easiest solution

It could be alignment or it could be that unsigned long is actually 64 bits.

The output from this would determine either or both cases:

#include <stdio.h>
#include <stddef.h>

struct struct_header {
	unsigned long offset;
	char magicCookie[4];
	unsigned long unknown;
} typedef struct_header;

int main()
{
	printf("sizeof %u %u \n", sizeof(struct_header), sizeof(unsigned long));
	printf("offset %u %u\n", offsetof(struct_header,magicCookie), offsetof(struct_header,unknown));
	return 0;
}

The output:
sizeof 24 8
offset 8 16

My understanding of the C++ standard was that unsigned long is always 32 bits. If you want a 64-bit integer use "long long" or "unsigned long long". But that does not appear to be the case anymore.

In any event, I'll change the headers to use uint32 and see if that helps. At best a nitpick since I can run it as a 32-bit application. But I spent enough time looking into this, so I might as well track down the source of the problem.
