To: cygwin-patches; +Cc: Jon Turney
For ease of reviewing, this patch doesn't contain changes to generated
files which would be made by running ./autogen.sh.
v2:
* Include tzmap.h in BUILT_SOURCES
* Make per-file flags appear after user-supplied CXXFLAGS, so they can
override optimization level.
* Correct .o files used to define symbols exported by libm.a
* Drop gcrt0.o mistakenly included in libgmon.a
* Add missing line continuations in GMON_FILES value
v3:
* use per-file flags for .c compilation
* override C{XX,}FLAGS, as they are set on the command line by top-level make
v4:
* Drop -Wno-error=write-strings from path_testsuite CXXFLAGS
v5:
* Update for changes in master
- Add -fno-threadsafe-statics to CXX flags
- Add hypotl.cc
- Remove fenv.cc (in favour of newlib), add fenv.c stub
- Add proc.5 manpage rules

Sorry about getting distracted from this. To summarize what I believe
were the outstanding issues with v3 [1]:
[1] https://cygwin.com/pipermail/cygwin-patches/2020q4/010827.html
* 'INCLUDES' is the old name for 'AM_CPPFLAGS' warning from autogen.sh
I plan to clean this up in a future patch
* 'ps$(EXEEXT)' previously defined' warning from autogen.sh
It seems to be a shortcoming of automake that there's no way to suppress
just that warning.
One possible solution is build ps.exe with a different name and rename
it while installing, but I think that is counter-productive (in the
sense that it trades this warning for making the build more complex to
understand)
* some object files are in a unexpected places in the build file
hierarchy (compared to naive expectations and/or the non-automake build)
I'm not sure if this is merely an aesthetic issue, or if there are
problems this causes.

This is the only minor qualm I have with this patch. It would be nice
to have the mingw sources and .o files in the mingw subdir. It would
simply be a bit cleaner. The files shared between cygwin and mingw
(that's only path.cc, I think) could be handled by an include, i. e.
utils/
path.cc (full implementation)
utils/mingw/
path.cc:
#include "../path.cc"
However, this isn't a showstopper, feel free to push what you're comfortable
with.
Still, wWhat do you think? Any problem to move the mingw stuff to the
mingw subdir entirely?
Thanks,
Corinna

I wonder if it wouldn't make sense to split out the mingw-only parts
of path.cc entirely. I had a quick view into the file and it turns
out that of the almost 1000 lines in this file, only about 100 lines
are used by mount. All the rest is only used by mingw code, i. e.,
cygcheck and strace.
That's obviously not part of this patch, but something we should keep
in mind for a later cleanup.

I tried this as a POC and it's not much of a problem. See the below
patch. Cleaning up the includes is still to do.

I'm confused about how the generated files are going to get regenerated when
necessary. I see calls to autogen (which I guess is /usr/bin/autogen.exe from
the autogen package) in the Makefiles, but I don't see any calls to autogen.sh.
Is the latter no longer needed?

Oh, never mind. The Makefiles just call autoconf, etc., as needed.

That's some cygnus top-level weirdness I don't understand.

There is (still) an autogen.sh in winsup/ ...

... but you should now never need to explicitly use it, as
('maintainer-mode') rules now exist in the Makefile to do what's needed.
If you do need to make changes in the autofoolery which are going to be
pushed, then specific versions of the autotools still need to be used
(to avoid these generated files thrashing between forms generated by
different versions)

Some possible items of future work I noted:
* Documentation is now always built (rather than dangerously ignoring
any errors)
Although this is half-arsed at the moment, as we don't require the
documentation tools at configure time, we'll just fail when the rules
are executed if they are missing.
Perhaps there should be explicit configuration to build documentation or
not?
* Use AM_V_GEN to silence (most?) custom rules
* -Wimplicit-fallthrough, -Werror could (should?) be set in top-level
Makefile.am.common, rather than individual subdirs
* Some custom rules have multiple outputs and workarounds to ensure the
rule only runs once
Ideally these would be re-written using make 4.3 'grouped targets', but
perhaps not yet...
* Some custom rules could be simplified
e.g. mkvers.sh generates version.cc and winver.rc, then runs windres on
windver.rc
* 'make our include directories absolute so we don't have to worry about
making them relative to the subdirectory we happen to be building in' is
sufficiently obscure that it at least deserves a comment.
* Rather than a huge list of --replace options to mkimport inline in the
Makefile, it might be more sensible to augment that tool the read a list
of replacement names from a file, and put them there.

Perhaps keep -Werror for Cygwin sources only where we can directly deal with new
warnings generated due to prompt gcc releases with improvements under Cygwin
(thanks to Achim and JonY).
With other distros' gcc releases lagging, package builds are getting more
warnings during cygport builds, which would have to be dealt with either by more
Cygwin patches and/or working with upstream, by toggling off -Werror, or
specific -Wno-... options which could result in suppressing useful output, as
well as delaying package releases.

Careful, the implicit-fallthrough values are different. Not saying they
*have* to be different, but that certainly requires code changes.

No, -Werror should be used for all source dirs under winsup.

`make doc'?
It wouldn't be tricky to add that to the cygwin.cygport file...

I'm not sure I understand... -v, please?

Yeah, that's probably the right thing to do.

Yeah, that's why it needs comment :)
realdirpath() in winsup/configure.ac makes paths absolute (and canonical)
Therefore we can use things set with it (AC_CYGWIN_INCLUDES,
target_builddir, winsup_srcdir) in Makefile.am in arbitrarily deep
subdirectories, and things just happen to work (which wouldn't be the
case if they contained relative paths)
It's all a hangover from when it used to be even more complex (see
commit 39e8d907), and looking at this again, this could probably be
cleaned-up some more (perhaps using $top_builddir, $top_srcdir?).
