I did a locate on ib_util, and only got ib_util.h in the include
files. That only contains a forward declaration for ib_util_malloc.
Further, a strings in /usr/lib on *.a and *.so (strings *.a *.so |
grep ib_util) leads to nothing. What file should I be linking to?

The file is reproduced below:
#include <stdio.h>
#include <stdlib.h>
#include <ibase.h>
#include <ib_util.h>

#define BUFFER_SIZE (100)
#define LOW32MASK (0xFFFFFFFFULL)
#define HIGH32MASK (0xFFFFFFFFULL << 32)

#ifdef DEBUG_BUILD_EXE
#define MALLOC malloc
#else
#define MALLOC malloc /* Declared as ib_util_malloc before */
#endif

char * ISC_EXPORT prettyPrintInt64(ISC_UINT64 *in) {
char *retval = MALLOC(BUFFER_SIZE);
snprintf(retval,BUFFER_SIZE-1,"%llu -
%llu",((*in)&HIGH32MASK)>>32,(*in)&LOW32MASK);
return retval; // Free me
}

ISC_UINT64 ISC_EXPORT unPrettifyInt64(char *in) {
unsigned int a,b;
sscanf(in,"%u - %u",&a,&b);
return ((unsigned long long)a << 32) + b;
}

/* EOF */
