Previously export_dynamic was set in src/makefiles/Makefile.$port. For solaris
this required exporting with_gnu_ld. The determination of with_gnu_ld would be
nontrivial to copy for meson PGXS compatibility. It's also nice to delete
libtool.m4.
This uses -Wl,--export-dynamic on all platforms, previously all platforms but
FreeBSD used -Wl,-E. The likelihood of a name conflict seems lower with the
longer spelling.

This way we don't need RANLIB anymore, making it a bit simpler for the meson
build to generate Makefile.global for PGXS compatibility.
FreeBSD, NetBSD, OpenBSD, the only platforms where we didn't use AROPT=crs,
all have supported the 's' option for a long time.
On macOS we ran ranlib after installing a static library. This was added a
long time ago, in 58ad65ec2def. I cannot reproduce an issue in more recent
macOS versions. This is removed now.
Based on discussion with Tom, I left the 'touch' at the end of static
libraries generation, added in 826eff57c4c, in place. While it looks like
current versions of Apple's ar/ranlib don't need it, it was needed not too
long ago.

Move DLSUFFIX from makefiles into header files for all platforms.
Move the DLSUFFIX assignment from src/makefiles/ to src/templates/,
have configure read it, and then substitute it into Makefile.global
and pg_config.h. This avoids the need for all makefile rules that
need it to locally set CPPFLAGS. It also resolves an inconsistent
setup between the two Windows build systems.

Move the platform-dependent logic that sets CFLAGS_SL from
src/makefiles/Makefile.foo to src/template/foo, so that the value
is determined at configure time and thus is available while running
configure's tests.
On a couple of platforms this might save a few microseconds of build
time by eliminating a test that make otherwise has to do over and over.
Otherwise it's pretty much a wash for build purposes; in particular,
this makes no difference to anyone who might be overriding CFLAGS_SL
via a make option.
This patch in itself does nothing with the value and thus should not
change any behavior, though you'll probably have to re-run configure
to get a correctly updated Makefile.global. We'll use the new
configure variable in a follow-on patch.
Per gripe from Kyotaro Horiguchi. Back-patch to all supported branches,
because the follow-on patch is a portability bug fix.

Rather than define ld_library_path_ver with a big nested $(if), just
put the overriding values in the makefiles for the relevant ports.
Also add a variable for port makefiles to append their own stuff to
with_temp_install, and use it to set LD_LIBRARY_PATH_RPATH=1 on
FreeBSD which is needed to make LD_LIBRARY_PATH override DT_RPATH
if DT_RUNPATH is not set (which seems to depend in unpredictable ways
on the choice of compiler, at least on my system).
Backpatch for the benefit of anyone doing regression tests on FreeBSD.
(For other platforms there should be no functional change.)

It's important for link commands to list *.o input files before -l
switches for libraries, as library code may not get pulled into the link
unless referenced by an earlier command-line entry. This is certainly
necessary for static libraries (.a style). Apparently on some platforms
it is also necessary for shared libraries, as reported by Donald Dong.
We often put -l switches for within-tree libraries into LDFLAGS, meaning
that link commands that list *.o files after LDFLAGS are hazardous.
Most of our link commands got this right, but a few did not. In
particular, places that relied on gmake's default implicit link rule
failed, because that puts LDFLAGS first. Fix that by overriding the
built-in rule with our own. The implicit link rules in
src/makefiles/Makefile.* for single-.o-file shared libraries mostly
got this wrong too, so fix them. I also changed the link rules for the
backend and a couple of other places for consistency, even though they
are not (currently) at risk because they aren't adding any -l switches
to LDFLAGS.
Arguably, the real problem here is that we're abusing LDFLAGS by
putting -l switches in it and we should stop doing that. But changing
that would be quite invasive, so I'm not eager to do so.
Perhaps this is a candidate for back-patching, but so far it seems
that problems can only be exhibited in test code we don't normally
build, and at least some of the problems are new in HEAD anyway.
So I'll refrain for now.

This was used in a time when a shared libperl or libpython was difficult
to come by. That is obsolete, and the idea behind the flag was never
fully portable anyway and will likely fail on more modern CPU
architectures.

linking both executables and shared libraries, and we add on LDFLAGS_EX when
linking executables or LDFLAGS_SL when linking shared libraries. This
provides a significantly cleaner way of dealing with link-time switches than
the former behavior. Also, make sure that the various platform-specific
%.so: %.o rules incorporate LDFLAGS and LDFLAGS_SL; most of them missed that
before. (I did not add these variables for the platforms that invoke $(LD)
directly, however. It's not clear if we can do that safely, since for the
most part we assume these variables use CC command-line syntax.)
Per gripe from Aaron Swenson and subsequent investigation.

another section if required by the platform (instead of the old way of
building them in section "l" and always transforming them to the
platform-specific section).
This speeds up the installation on common platforms, and it avoids some
funny business with the man page tools and build process.

somewhat by adding CFLAGS where the compiler is used and Makefile.shlib
already used CFLAGS.
|
|
no evidence that any currently-supported platform needs this, and good
reason to think that any platform that did need it couldn't use the static
libraries anyway --- libpq, at least, has circular references. Removing
the code shuts up tsort warnings about the circular references on some
platforms.

I tried snapshot(Oct30) and made some patches.
# I think that it is confused to manage both Makefile.shlib and
# makefiles/Makefile.*, don't you?
* configure
Now FreeBSD 2.X is not supported..., so I added its entry.
If ELF_SYSTEM is set, gmake treat it defined even though
it is "false". So nothing should be set to use "ifdef".
BSD_SHLIB etc. may have same problems.
* Makefile.shlib
As you said, FreeBSD entry is much like BSD's.
I only added ELF_SYSTEM code.
* makefiles/Makefile.freebsd
Ifdef/else/endif can not be indented with TABs.

Added a ELF_SYS variable and check to configure.in...

|
|
-Bforcearchive flag for ld...
Give FreeBSD its own special Makefile to get around the "bug"
