Hi all,

I want to compile the source code of Advanced Programming in the Unix
Environment(APUE) 3rd edition, and I encountered some difficulties.
After executing "make", I got this message:

make[1]: Leaving directory `/home/drizzlex/apue.3e/threads'
make: *** [all] Error 1

#ifdef SOLARIS
#define heapsort qsort
#else
extern int heapsort(void *, size_t, size_t,
int (*)(const void *, const void *));
#endif

If I change these code to

You need the 'libbsd' package, available in EPEL.
