Re: Porting C programs written for AIX

Hi Jim,

'char *newformat[30];' is a declaration of an array of 30 character
pointers. I would guess that the 'format' variable is either declared
similarly, or declared as a pointer to char pointer (char **). It appears
that the code is trying to cast the pointer to a char pointer to get at the
first element of the array. This shouldn't have even worked on AIX.
Without seeing the rest of the code for context I'm not sure what the
intended behavior here is, but I would say that at the error point it would
appear that they are trying to compare the first element of each array. I
would recommend replacing the strcpy with something like this:

strcpy( newformat[0], format[0]);

That should get rid of the error. Without seeing the rest of the code I'm
not sure whether it's the correct thing to do though...

Thanks,

Aaron Albertson

this is our include section (which I am seeing referenced with err

CZM0280)

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sqludf.h>
#include "veapi.h"
#include "vefpe.h"

Working on a proof of concept project to port a aix implementation of C

(I

am told it is C, not C++ but wouldn't know the diff if it hit me in the
face..)

Large multi platform company, we are the only Power i in the mix of AIX
and MS-SQL and .net.
The C code is an encryption package where we can all pass data back and
forth (and we do a lot of that) but handle the encryption of sensitive
info. They have written C wrappers around a package of C from HP called
Voltage.
We have the source for the wrappers, but compiling the C on "i" not
working. We have solved the includes issues, but getting down to

like line 47 :

IS there a conversion of source needed to ILE C?
Is line 40 char *newformat[30]; correct - I can't find anything

like

that in google...
