Hi Dan,
I have gotten "kuang" from watchmaker directory. I found that it would
not compile directly on our ULTRIX 2.2 system. The problem is in
filewriters.c which produces the following compilation error:
cc -g filewriters.c -o filewriters
filewriters.c: 28: S_GWRITE redefined
filewriters.c: 58: S_IWRITE: macro recursion
filewriters.c: 65: S_IWRITE: macro recursion
*** Error code 1
Stop.
This seems to be caused by the definition of S_GWRITE in
filewriters.c:
..............................extracts from filewriters.c
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <grp.h>
#include <pwd.h>
/* I had to delete this define to get compilation on ULTRIX 2.2
problem is "recursive" definition - see /usr/include/sys/stat.h */
/*#define S_GWRITE (S_IWRITE >> 3) /* Group write access. */
#define S_OWRITE (S_IWRITE >> 6) /* Other write access. */
line 58... if (S_GWRITE & (buf.st_mode)) {
line 65... if (S_OWRITE & buf.st_mode) {
..................
I suspect that my /usr/include/sys/stat.h is different from the one
running on the ATHENA workstations.
.........................extracts from /usr/include/sys/stat.h
#define S_GWRITE 0000200 /* write permission, owner */
...
#define S_IREAD S_GREAD
...
#define S_IWRITE S_GWRITE
.................
Elimination of the define in filewriters.c permitted compilation and
execution, but I don't know how it affected the logic of the program.
