Hm. So if we're giving up on the idea of ever getting rid of PGDLLIMPORT,
we ought to actually remove that, so that the Cygwin build works more like
the other Windows builds?
Hm, I don't see a big advantage in detecting the errors as It won't
hugely increase the buildfarm coverage. But --auto-import seems to
require marking the .text sections as writable, avoiding that seems to
be a good idea if we don't need it anymore.
Given the rather small number of Windows machines in the buildfarm,
I'd really like them all to be on the same page about what's valid
and what isn't. Having to wait ~24 hours to find out if they're
all happy with something isn't my idea of a good time. In any case,
as long as we have discrepancies between them, I'm not going to be
entirely convinced that any of them are telling the full truth.
I'm going to go remove that switch and see if brolga starts failing.
If it does, I'll be satisfied that we understand the issues here.
I wouldn't assume that _anything_ Cygwin does makes sense, or is
consistent with anything else.
Of course, I disagree ;-)
Its attempts to produce UNIX-like behaviour on Windows cause some truly
bizarre behaviour at times.
unfortunately our baseground (Windows) is limiting us.
It is not totally unfair to compare the level of weirdness of Cygwin to
that of WINE, though they operate in completely different ways. I
wouldn't suggest making any conclusions about the _other_ platforms
based on Cygwin.
My personal experience is that a UNIX-vanilla source build 99% right
on recent cygwin.
The problem with postgreql make/build system is that it tries to guess
platform behavior and that is not fix in time.
Porting a new platform to postgresql from scratch will be a
very hard effort
Automake/Autoconf makes it much more simple; as its aim is to
test features not platforms.
Cmake also makes it right, now. We teach it that cygwin is a unix
platform not a win32 platform
I am biased, of course.
