Hello,
I'm trying to solve my other problem (mentioned in "fopen() to open a
HFS path") by creating a small test program to look for the error. It
is a Mach-O C++ Console program as CW10 created it for me. In the
program, I need both C++-style iostream (cout and company) and plain
vanilla fopen-fread-fclose. I can compile but I get tons of undefined
reference errors when linking (eg. PBHOpenDFSync, FSOpenFork,
ResolveAliasFile). CW makes me link against ctr1.o and
MSL_All_Mach-O.lib but what else do I need to link against to resolve
these references? I tried quite a few libraries provided by CW but none
of them worked.
Thanks,
Gábor |

| Unfortunately for my current case, this framework has been added by
default by CodeWarrior, yet it fails to link.
Bye,

Of course, you need to add the Carbon framework.

Thorsten,
yes, that helped, thanks. However, the program still shows very strange
behavior when run:
#define MAXENTRIES 50000
typedef struct tagENTRY {
WORD w1; // WORD and similar are defined elsewhere
WORD w2;
WORD w3;
BYTE f;
BYTE h;
} ENTRY, *LPENTRY;
ENTRY Table[MAXENTRIES];
FILE* f = NULL;
fdict = fopen ("/Users/djg/Documents/...", "rb");
fread (&Table[0], sizeof(ENTRY), 1, f);
and this fread() results in an immediate Bus Error (I omitted the error
handling here but the file is opened all right).
Bye,
Gábor |

Scott,
only if it were that simple...  )
No, it was my mistake when editing the snippet to make it more generic,
fdict is actually f, I just forgot to modify that instance. So, it is f
= fopen(), it isn't NULL because I check for it, it is opened, then
comes the fread() and the fireworks.
Bye,
Gábor |

Well, f is NULL because you never assign anything to it. But then again, you
don't define fdict in this snippet so it wouldn't compile anyway. Try
posting the snippet again? |

I think you should just add the "System.framework" in the framework tab of
your project. You will find the various frameworks in
/System/Library/Frameworks on your HD.

Was the file saved by the same code? Are you familiar with structure
padding?
