------------------------+--------------------------------
 Reporter:  rharwood@…  |      Owner:  macports-tickets@…
     Type:  defect      |     Status:  new
 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.2.1
 Keywords:              |       Port:  dbus
------------------------+--------------------------------
 As requested from #42994, here is a ticket for dbus build failure on 10.6.

 This build failure is due to missing O_CLOEXEC flag to open(2) on 10.6,
 like so:

 {{{
 robbie at osxserver:~$ cat test.c
 #include <fcntl.h>

 #include <sys/stat.h>
 #include <sys/types.h>

 int main() {
   open("", O_CREAT);
   return 0;
 }
 robbie at osxserver:~$ gcc test.c
 robbie at osxserver:~$
 }}}

 while

 {{{
 robbie at osxserver:~$ cat test.c
 #include <fcntl.h>

 #include <sys/stat.h>
 #include <sys/types.h>

 int main() {
   open("", O_CREAT | O_CLOEXEC);
   return 0;
 }
 robbie at osxserver:~$ gcc test.c
 test.c: In function 'main':
 test.c:7:22: error: 'O_CLOEXEC' undeclared (first use in this function)
    open("", O_CREAT | O_CLOEXEC);
                       ^
 test.c:7:22: note: each undeclared identifier is reported only once for
 each function it appears in
 robbie at osxserver:~$
 }}}
