Hello,
I had to apply the attached patch to build on OS X.
The error before applying the patch is:
/usr/include/unistd.h:691:6: error: conflicting types for
'getpeereid'
int getpeereid(int, uid_t *, gid_t *);
^
In file included from ipc_eid.c:3:0:
getpeereid.h:6:12: note: previous declaration of 'getpeereid' was
here
extern int getpeereid (int, int *, int *) ;
^
The patch also changes the types of args to getpeereid from int to
unsigned int. Without that part, I get the warning (it still compiles):
ipc_eid.c: In function 'ipc_eid':
ipc_eid.c:9:3: warning: pointer targets in passing argument 2 of
'getpeereid' differ in signedness [-Wpointer-sign]
if (getpeereid(s, &dummyu, &dummyg) < 0) return -1 ;
^
In file included from djbunix.h:6:0,
from webipc.h:16,
from ipc_eid.c:4:
/usr/include/unistd.h:691:6: note: expected 'uid_t *' but argument
is of type 'int *'
int getpeereid(int, uid_t *, gid_t *);
^
For what it's worth, new releases of both execline and s6 seemed to
build OK.
