[gnome-core] glib2 needs dependency on libpoll?

[Jack R. <jre...@co...>]

I think maybe the glib2 package needs to declare a dependency on  
libpoll, some version greater than 1.4-1 (that is, 1.4-1 doesn't  
work, and 1.4-11, the current version, does work).  Does that seem  
right?  I'm fairly new at this stuff, but here's my reasoning:

On a 10.4.5 system, I was unable to "fink update glib2".  The failure  
was (this comes from config.log):

> configure:38574: checking value of POLLNVAL
> configure:38884: gcc -o conftest -O3 -funroll-loops -fstrict- 
> aliasing -Wall -no-cpp-precomp -isystem /sw/include - 
> D_POLL_EMUL_H_   conftest.c -lintl  -L/sw/lib >&5
> conftest.c: In function 'longval':
> conftest.c:135: error: 'POLLNVAL' undeclared (first use in this  
> function)


Research discloses that I had a /sw/include/sys/poll.h that was being  
included, and which indeed does not define POLLNVAL.  There seem to  
be quite a number of other poll.h's on my system, but all of them  
either define POLLNVAL or #include a related file that does so.  The  
"right" one is probably /usr/include/poll.h, or its brother /usr/ 
include/sys/poll.h.  Only the /sw/include one is POLLNVAL-less.

Dpkg tells me that the POLLNVAL-less poll.h is a part of libpoll,  
which at this point in time was version 1.4-1.

Another system of mine was working fine; it turns out to have libpoll  
version 1.4-11 (what a difference a one makes!).  It has no /sw/ 
include/sys/poll.h.

"fink update libpoll" got my unhappy system up to 1.4-11, which  
caused the poll.h under /sw/ to disappear, and now "fink update  
glib2" works just fine, bringing me to 2.8.6-122.

I suppose this might not actually be so much a "dependency" as an  
"anti-dependency": I don't know, but perhaps  glib2 would be fine  
with no libpoll at all (at least in Tiger, where apparently the  
facility is now standard).

There appears to be some history about all this, e.g.,

   http://article.gmane.org/gmane.os.apple.fink.gnome/717/match=libpoll

... but the circumstances by now, with the various versions i mention  
above, seem to be different from how they were then (2004-08-12).
