Hi Commander Sirow,

Thanks for the report!  There are enough things to track down here that
I opened a bug report, and put you on the Cc.

AIUI the canonicalize_path binding that gnulib provides for mingw ends
up shelling out to `rm' and other commands.  They claim that it is
reasonable to install these on a mingw system; I don't know.  But is it
possible that you don't have these files?

See http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/25451/focus=25466.

Let's deal with the first one first.

I have a similar, although slightly different in details, experience.
(I will post the details as soon as the saga is finished for me and I
have all it figured out ;-)

I don't think this is true; at least I don't see any such shelling out
in lib/canonicalize-lgpl.c, which I believe is the module you allude
to.

The problem, AFAIK, is entirely different and quite mundane:
canonicalize_file_name simply does not support Windows-style
D:/foo/bar file names, nor does it support backslashes as separators
in file names.

My evidence is that I added an fprintf to canonicalize-path where it
calls canonicalize_file_name, and the file name passed to it was
entirely reasonable, something like

   D:\path\to\guile-2.03/module/ice-9/boot-9.scm

(or some such, I'm writing this from my faulty memory).

I think I know how to fix canonicalize_file_name, and I will send a
tentative patch later, perhaps even today, when I have it working and
get past this abort.

The patch to fix canonicalize_file_name is below.  It gets me through
the "GEN guile-procedures.texi" step.

The next failure is this:

       GEN    guile-procedures.texi
     Backtrace:
     In unknown file:
	?: 3 [boot-closure #t #<catch-closure 2903300> ...]
	?: 2 [catch-closure]
	?: 1 [primitive-eval ((@ # %) (begin # # #))]
	?: 0 [primitive-load-path "d:\\usr\\eli\\utils\\guile-2.0.3\\libguile/d:/usr/eli/utils/guile-2.0.3/meta/guild"]

     ERROR: In procedure primitive-load-path:
     ERROR: In procedure canonicalize-path: No such file or directory

which again looks like failure to treat d:/foo/bar file names as
absolute.

Some random poking around reveals this in ice-9/boot-9.scm:

    (define (absolute-path? path)
      (string-prefix? "/" path))

which looks a likely culprit.  Changing it to recognize d:/foo/bar
absolute file names indeed solves this problem.  (I'm too embarrassed
to show the changes I did for that, as I know nothing about Scheme,
and my code is too ugly to go into upstream.  I don't even know how to
condition the change on the underlying platform being MS-Windows.)

The next problem is here:

       GUILEC ice-9/eval.go
     Backtrace:
     In unknown file:
	?: 5 [boot-closure #t #<catch-closure 231fd40> ...]
	?: 4 [catch-closure]
	?: 3 [primitive-eval ((@ # %) (begin # # #))]
	?: 2 [chmod #<input-output: ice-9/eval.go.9IiPxC 6> 438]
	?: 1 [boot-closure system-error "chmod" ...]
	?: 0 [delete-file "ice-9/eval.go.9IiPxC"]

     ERROR: In procedure delete-file:
     ERROR: In procedure delete-file: Permission denied

This happens because Guile calls fchmod, which is #define'd to -1 on
MinGW.

Solution: #define it to zero, since chmod is mostly a no-op on Windows
anyway.  This passes the eval.go step (and then fails while compiling
psyntax-pp.go; to be continued...).

As an aside, if this kind of operation is a frequent one, I'd suggest
to change the caller so that it never uses fchmod on MS-Windows,
because this function cannot be implemented there, except on the
latest versions (Windows 7 etc.).  Use chmod instead, even if that is
less efficient.

Btw, why doesn't the backtrace show file names, but says "unknown
file"?  Is this expected during the build, or is there another bug to
look for?  If the latter, any hints as to where to look for the
reason(s)?

Here's the patch for canonicalize-lgpl.c to make it Windows-friendly.
I will send it to the gnulib developers as well.

Can you send this one to bug-gnulib@gnu.org?  (All the code under lib/
comes from Gnulib.)

(The rest of your investigation is interesting!)

Thanks,

For the record, my report to bug-gnulib is here:

  http://lists.gnu.org/archive/html/bug-gnulib/2012-01/msg00253.html

> (The rest of your investigation is interesting!)

Here's some more ;-)

In the last episode, we stopped here:

       GUILEC ice-9/psyntax-pp.go
     Throw without catch before boot:
     Throw to key system-error with args ("make_objcode_from_file" "~A" ("No error") (0))Aborting.

It turns out that this happens because Guile reads and writes objcodes
from/to *.go files in text mode.  My solution was to use binary mode
in writing in mkstemp.c:

      fd = open (template, O_RDWR|O_BINARY|O_CREAT|O_EXCL, 0600);

and in reading in objcodes.c:load-objcode:

      fd = open (c_file, O_RDONLY | O_BINARY | O_CLOEXEC);

While the latter change looks as TRT in all cases, the former does
not: there's no guarantee that mkstemp! will be used only for
outputting *.go files.  It is probably best to have a wrapper around
mkstemp!, and use only that for writing to *.go files in compile.scm.

Next obstacle: Abort while compiling ice-9/poll.scm:

     In ice-9/eval.scm:
      389: 19 [eval # #]

     ice-9/boot-9.scm:119:20: In procedure delete-file: Permission denied
     make[2]: *** [ice-9/poll.go] Error 1

This happens because poll.scm does this:

     (eval-when (eval load compile)
       (load-extension (string-append "libguile-" (effective-version))
		       "scm_init_poll"))

while scm_init_poll has this snippet:

     static void
     scm_init_poll (void)
     {
     #if HAVE_POLL
       scm_c_define_gsubr ("primitive-poll", 4, 0, 0, scm_primitive_poll);
     #else
       scm_misc_error ("%init-poll", "`poll' unavailable on this platform", SCM_EOL);
     #endif

Since Windows doesn't HAVE_POLL, scm_misc_error throws an error.

It doesn't sound wise to fail the entire build procedure due to `poll'
being unavailable (AFAIK, not only MS-Windows lacks that library
function).  Maybe poll.scm should be compiled, or maybe it should do
some clever tricks around load-extension to avoid throwing an error at
compile time.  I'm not a Guile or Scheme person, so I cannot suggest a
good solution.

As a workaround, I used "make -k" to allow the build to continue past
this point.

There's another problem in the above backtrace: The form that catches
the thrown error cannot delete the temporary file
ice-9/poll.go.LORZMf, because it tries to delete a file that is still
open.  Changing call-with-output-file/atomic to close the temporary
file before deletion, like this:

     (define* (call-with-output-file/atomic filename proc #:optional reference)
       (let* ((template (string-append filename ".XXXXXX"))
	      (tmp (mkstemp! template)))
	 (call-once
	  (lambda ()
	    (with-throw-handler #t
	      (lambda ()
		(proc tmp)
		(chmod tmp (logand #o0666 (lognot (umask))))
		(close-port tmp)
		(rename-file template filename))
	      (lambda args
		(close-port tmp) ;; <<<<<<<<<<<<<<<<<<<<<<<<<<<
		(delete-file template)))))))

solves the problem, and we can now see the correct backtrace:

The build still stops, but now we have a human-readable description of
the reason.

The problem in poll.scm causes another failure while compiling

     make[2]: *** [web/server/http.go] Error 1

Other than that, the build finally succeeds!

P.S.  I found a couple of other possible places that don't support
Windows file names:

   ice-9/boot-9.scm:

     (define* (load-in-vicinity dir path #:optional reader)
       (define (canonical->suffix canon)
	 (cond
	  ((string-prefix? "/" canon) canon)
	  ((and (> (string-length canon) 2)
		(eqv? (string-ref canon 1) #\:))
	   ;; Paths like C:... transform to /C...
	   (string-append "/" (substring canon 0 1) (substring canon 2)))
	  (else canon)))


   system/base/compile.scm:

       (define (canonical->suffix canon)
	 (cond
	  ((string-prefix? "/" canon) canon)
	  ((and (> (string-length canon) 2)
		(eqv? (string-ref canon 1) #\:))
	   ;; Paths like C:... transform to /C...
	   (string-append "/" (substring canon 0 1) (substring canon 2)))
	  (else canon)))

I don't understand the "Paths like C:... transform to /C..." part.
Does that assume Cygwin?  Because the "transformed" file names will
not work in the native Windows build, which is what MinGW produces.

P.P.S.  I have still a few non-fatal warnings to investigate and
perhaps report, if they turn out to be real problems.  And then
there's a test suite.  Stay tuned.

As promised, still more issues below.

1. Compilation warnings in deprecation.c:

       SNARF  deprecation.x
     deprecation.c:40:1: warning: "vsnprintf" redefined
     In file included from deprecation.c:25:
     ../lib/stdio.h:1605:1: warning: this is the location of the previous definition

This is because deprecation.c does this:

     /* Windows defines. */
     #ifdef __MINGW32__
     #define vsnprintf _vsnprintf
     #endif

but lib/stdio.h already did the same.  My solution was to add an
"#ifdef vsnprintf" condition to deprecation.c to avoid redefinition.

2. Compilation warning in expand.c:

       SNARF  expand.x
     expand.c:52:1: warning: "VOID" redefined
     In file included from d:/usr/include/windef.h:253,
		      from d:/usr/include/windows.h:48,
		      from d:/usr/include/winsock2.h:22,
		      from ../libguile/iselect.h:36,
		      from ../libguile/threads.h:30,
		      from ../libguile/gc.h:29,
		      from ../libguile/_scm.h:75,
		      from expand.c:27:
     d:/usr/include/winnt.h:75:1: warning: this is the location of the previous definition
     expand.c:54:1: warning: "CONST" redefined
     In file included from d:/usr/include/windows.h:48,
		      from d:/usr/include/winsock2.h:22,
		      from ../libguile/iselect.h:36,
		      from ../libguile/threads.h:30,
		      from ../libguile/gc.h:29,
		      from ../libguile/_scm.h:75,
		      from expand.c:27:
     d:/usr/include/windef.h:39:1: warning: this is the location of the previous definition

This is because expand.c does:

     #define VOID(src) \
       SCM_MAKE_EXPANDED_VOID(src)
     #define CONST(src, exp) \
       SCM_MAKE_EXPANDED_CONST(src, exp)

and Windows headers have their own definitions for VOID and CONST.

My solution was to add this to expand.c:

     #ifdef VOID
     #undef VOID
     #endif
     #ifdef CONST
     #undef CONST
     #endif

However, I really suggest that expand.c uses some less ubiquitous
symbol names, like SCM_CONST and SCM_VOID.

3. Compilation warning in filesys.c:

       SNARF  filesys.x
     filesys.c:119:1: warning: "mkdir" redefined
     In file included from ../lib/sys/stat.h:47,
		      from filesys.c:92:
     ../lib/sys/stat.h:808:1: warning: this is the location of the previous definition

This is because filesys.c does this:

     /* Some more definitions for the native Windows port. */
     #ifdef __MINGW32__
     # define mkdir(path, mode) mkdir (path)

But gnulib already redirected `mkdir' to its replacement function.  My
solution: don't define if already redirected.  To that end, I added
the following condition before the above #define:

     /* When configured to use the gnulib replacement, don't redefine
	mkdir, as it is already redirected to the replacement, see
	lib/sys/stat.h.  */
     # if !GNULIB_defined_rpl_mkdir

I'm not sure using GNULIB_defined_rpl_mkdir is TRT here, but I didn't
find a better way.

4. Missing setenv needed by dynl.c:

       CC     dynl.lo
     dynl.c: In function `augment_env':
     dynl.c:141: warning: implicit declaration of function `setenv'

Solution: add a setenv implementation.  However, I think Guile would
be better off using a more portable putenv instead.

5. Compilation error in net_db.c:

       CC     net_db.lo
     net_db.c:460: error: `AI_ALL' undeclared here (not in a function)

     net_db.c: In function `scm_getaddrinfo':
     net_db.c:663: warning: value computed is not used
     make[3]: *** [net_db.lo] Error 1

The reason is that this condition in net_db.c:

     #ifdef HAVE_WINSOCK2_H
     #include <winsock2.h>
     #else
     #include <sys/socket.h>
     #include <netdb.h>
     #include <netinet/in.h>
     #include <arpa/inet.h>
     #endif

is inappropriate when gnulib was used to wrap Windows socket
functions.  When gnulib _is_ used, the missing macros are already
defined by lib/sys/socket.h.  Therefore, I modified the condition to:

     #if HAVE_WINSOCK2_H && !GNULIB_TEST_SOCKET
     #include <winsock2.h>
     # if HAVE_WS2TCPIP_H
     #  include <ws2tcpip.h>
     # endif
     #else
     #include <sys/socket.h>
     #include <netdb.h>
     #include <netinet/in.h>
     #include <arpa/inet.h>
     #endif

using GNULIB_TEST_SOCKET as evidence that gnulib is being used.  I'm
not sure GNULIB_TEST_SOCKET is TRT, but I saw no better candidate.
Maybe gnulib should provide us with a better macro.

6. Compilation warnings in socket.c:

       CC     socket.lo
     socket.c: In function `scm_inet_ntop':
     socket.c:349: warning: implicit declaration of function `inet_ntop'
     socket.c:349: warning: assignment makes pointer from integer without a cast
     socket.c:357: warning: assignment makes pointer from integer without a cast
     socket.c: In function `scm_inet_pton':
     socket.c:397: warning: implicit declaration of function `inet_pton'

This is again because gnulib headers are not included although
available, due to exclusive test of HAVE_WINSOCK2_H.  Solution: change
this in socket.c:

     #ifdef HAVE_WINSOCK2_H

to say this:

     #if HAVE_WINSOCK2_H && !GNULIB_TEST_SOCKET

The same caveat about GNULIB_TEST_SOCKET applies here.

This completes the description of problems I needed to overcome for
building Guile with MinGW+MSYS.  You may notice that my report is
slightly different from Commander Sirow's report that started this bug
report, where we cover the same turf:

 . I didn't need to define a `struct timespec', probably because I
   don't have Pthreads-w32 installed, and so pthread.h did not get
   included in my build.

 . I solved the problems in net_db.c differently (see above), and I
   believe more correctly.

Well, it turns out there's more to tell:

1. First, I forgot to tell before that I needed to configure with

     CPPFLAGS='-D_WIN32_WINNT=0x0501' ./configure ...

because if I don't use CPPFLAGS='-D_WIN32_WINNT=0x0501, the configure
script claims various network-related functions, like getaddrinfo and
getnameinfo) are not available, which is a lie.

     pairs.c:262:***Missing or erroneous #undef for scm_caaaar:

These come from the guile-func-name-check Awk script, because the
offending functions indeed lack the usual "#define FUNC_NAME" and
"#undef FUNC_NAME" directives.

Are these problems real?  If not, I'd suggest to modify the Awk script
to not emit them: people might get alarmed without a good reason.

     makeinfo --force -o guile-procedures.txt guile-procedures.texi || test -f guile-procedures.txt
     d:\usr\eli\utils\guile-2.0.3\libguile//guile-procedures.texi:10720: Cross reference to nonexistent node `Backslash Escapes' (perhaps incorrect sectioning?).
     d:\usr\eli\utils\guile-2.0.3\libguile//guile-procedures.texi:10415: Cross reference to nonexistent node `Network Address Conversion' (perhaps incorrect sectioning?).

and many more similar errors.

This is because guile-procedures.texi is not a complete Texinfo
source.  Since this command just generates a plain-text document, I
suggest to add --no-validate to makeinfo command-line switches.

4. Error in "make install-strip":

     make  install-data-hook
     make[5]: Entering directory `/d/usr/eli/utils/guile-2.0.3/meta'
     cd /d/usr/test/bin && rm -f guile-tools.exe && \
	     cp -p guild.exe guile-tools.exe
     cp: cannot stat `guild.exe': No such file or directory
     make[5]: *** [install-data-hook] Error 1

This happens because meta/Makefile.am has this:

     # What we now call `guild' used to be known as `guile-tools'.
     install-data-hook:
	     cd $(DESTDIR)$(bindir) && rm -f guile-tools$(EXEEXT) && \
	     $(LN_S) guild$(EXEEXT) guile-tools$(EXEEXT)

The $(EXEEXT) part should be removed.

5. Invoking the installed guile.exe aborts:

     system/repl/common.scm:139:25: In procedure make-repl:
     system/repl/common.scm:139:25: In procedure module-lookup: Unbound variable: times

This happens because HAVE_TIMES is not defined, as Windows doesn't
have `times' and the corresponding gnulib module was not imported to
Guile.

Like the problems with poll.scm, it sounds unwise to call at startup
procedures that depend on optional features which may not exist on the
underlying platform.  If guile.exe depends on some of these features,
it should fail to build if they don't exist.

I solved this by copy/pasting gnulib's times.c into stime.c.

6. I noticed that changes in C sources do not trigger recompilation of
   the *.scm files.  Should they?

     ERROR: In procedure char-ready?:
     ERROR: In procedure fport_input_waiting: Not fully implemented on this platform

This is because Windows has neither `poll' nor `select' nor FIONREAD,
which are the 3 mechanisms supported by fport_input_waiting.

I solved it by adding this to fports.c:

     #elif defined (__MINGW32__)
       DWORD input_events;

       if (!GetNumberOfConsoleInputEvents (_get_osfhandle (fdes), &input_events))
	 scm_syserror ("fport_input_waiting");
       return (int) input_events;

and also the necessary definition of struct tms needed by stime.c.
But really the gnulib `select' module should be imported into Guile,
because the above will DTRT only for keyboard input ports.

This, finally, allows to start up guile.exe and type several simple
commands.

Hi Eli,

Thanks for doing all the hard work!

I’m willing to apply your changes, but could you send them in ‘git
format-patch’ format, with a log in GNU ChangeLog style, to make it
easier?

In prevision of the of an increased contribution rate ;-), could you
assign copyright to the FSF?  At first sight, these patches may be
applicable without copyright assignment, but that’s the limit, I think.

Strangely enough, the cross-build to MinGW32 at
<http://hydra.nixos.org/jobset/gnu/guile-2-0/> is not showing any of
these.  Any idea why?  That’s with MinGW 3.18.

I’ll try Gnulib’s setenv module.

This seems to be the right thing, according to gnulib-common.m4:

Thanks for developing Guile.

I can certainly add ChangeLog entries, but `git format-patch' would be
harder.  I don't have git installed on my development machine (git is
a bit of PITA on Windows).  What's wrong with "diff -u"?  I can divide
the diffs into separate chunks of related changes, so it will be
easier for you to produce separate commits, if that's what you want
from `git format-patch'.  If there's another reason for your request,
please tell what that is and I will try to make your job easier as
much as I can.  But installing git and cloning the Guile repo just to
submit these changes is something I'd like to avoid if possible.

Will do.

I have exactly zero experience with the cross-build MinGW
environment.  My MinGW installation is 3.14, FWIW.

It’s OK, but lacks commit meta-data (author, log, etc.), so it’s less
convenient to apply.  But that’s fine, if you prefer this way.

Thanks,
Ludo’.

Is there a way to produce a text file with this information that you
could then submit to git instead of typing it by hand?  If so, I can
make such a file.

Don’t bother.  ;-)  Just send the diffs with ChangeLog entries, and
we’ll put it all together.

Thanks,

Hi Eli,

Ludovic said it already, but it bears repeating: thank you very much for
this investigation!

I would like to take this task off his back, assuming he's OK with it:
the release process was terribly long, and Ludo deserves a rest ;)

I will assume that the canonicalize_file_name issues will get resolved
eventually in gnulib, once your assignment completes.  I will go
through the rest of the issues.

One thing: Ludo mentions that he had success with a cross-compiled MinGW
3.18 (IIRC?).  You were trying with 3.14.  Apparently there are 3.19 and
3.20 releases out.  Do you know if this is important?  I am ignorant
regarding MinGW, unfortunately.

I'll follow up on your other issues and patches.

Andy

I don't think it is.  I think the reason for the difference is that
Ludo used a cross-compiled environment, whereas I did it on
MS-Windows.

I will try to send the patches with ChangeLog entries in a day or two.

Hi!

Andy Wingo <wingo@pobox.com> skribis:

Thank you.  :-)

> One thing: Ludo mentions that he had success with a cross-compiled MinGW
> 3.18 (IIRC?).

That’s on Hydra, and MinGW has since been upgraded to 3.20 there.  Note
that it’s a ‘--disable-networking’ build too, which is easier.

Thanks,
Ludo’.

That might just explain at least some of the problems that I hit, but
Ludo didn't.  As you can see in my reports, quite a few of them were
related to network code in some way.

As promised, the diffs that I suggest to install to take care of the
problems I bumped into are at the end of this message.

For your convenience, I grouped the changes into several related
groups, in case you'd like to make them separate commits.  Each group
is preceded by a short description (a candidate for a commit log
message) and ChangeLog entries for the changes.

In addition to the diffs, there are a few other changes for which I
don't show my changes, because they were ad-hoc and not very clean.
Instead, I describe what I think should be the "right" solutions for
them:

 . lib/canonicalize-lgpl.c -- does not support Windows absolute file
                              names.  Will be fixed in gnulib.

 . libguile/dynl.c -- lacks setenv.  Gnulib's setenv should be used.

 . libguile/expand.c -- Defines CONST and VOID.  Should define
                        SCM_CONST and SCM_VOID (or some other, less
                        ubiquitous, symbols) instead.

 . libguile/fports.c -- Doesn't implement fport_input_waiting when
                        neither poll nor select nor FIONREAD are
                        available, without which interactive guile
                        won't start.  Should use the gnulib select
                        module.

 . libguile/socket.c -- Lacks implementation of `times' for
                        MS-Windows, without which guile.exe aborts
                        during startup.  Should use the gnulib times
                        module.

 . module/ice-9/boot-9.scm -- absolute-path? does not support Windows
                              file names with drive letters.  Windows
                              absolute file names match the regex
                              "\([a-zA-Z]:\)?[\\/]".  I don't know
                              Scheme well enough to write this in a
                              clean way, sorry...


Here are the diffs:


	Fix startup of guile.exe on MS-Windows.

	* module/system/base/compile.scm (call-with-output-file/atomic):
	Call close-port before deleting the temporary file name, otherwise
	deletion fails on MS-Windows (cannot delete a file that is still
	open).

	* libguile/load.c (scm_init_load_path) [__MINGW32__]: Convert
	backslashes to forward slashes in values of GUILE_LOAD_PATH and
	GUILE_LOAD_COMPILED_PATH.

Hi Eli,

I'm terribly sorry for the delay here.  I realize you've probably paged
out all of these patches from memory, but I would like to pick up the
loose ends.

I see you got this into gnulib in November
(http://lists.gnu.org/archive/html/bug-gnulib/2012-11/msg00090.html).
I just updated our Gnulib so we have it now.  Thanks!

This change was made in Guile on 25 January 2012.

Fixed in Guile on July 6 2012.

Just added the module; thanks.

Added; thanks.

I'll deal with the patches in a separate mail.

Thanks again.  Glad Guile is now more friendly to MinGW.

Ludo, what do you think about the attached patch?  Eli, is it correct
and sufficient to fix path handling?

Subject: [PATCH] better handling of windows path conventions

* libguile/filesys.c (scm_system_path_convention): New function.
  Exported to Scheme only.

* module/ice-9/boot-9.scm (path-separator?, absolute-path?): New
  predicates.
  (path-separator-string): New global variable.
  (in-vicinity): Use the new procedures.
  (load-user-init, try-module-autoload): Use path-separator-string.
  (load-in-vicinity): Update canonical->suffix.  A Racket-style
  `reroot-path' would be nice.

* module/ice-9/psyntax.scm (include): Use global `absolute-path?'.

I think we must stick to GNU conventions–i.e., write “file name” when
speaking of the name of a file, as above, and “path” when speaking of a
search path.

This is important here because sooner or later someone will ask about
“path separators” (semicolon vs. colon), not to be confused with file
name or directory separators.

WDYT?

(Yes, there are counter-examples in Guile code, but that’s no excuse. ;-))

What about adding here a link to a page that describes “UNC”?

Otherwise, looks good to me, and it’s great that progress is made on
that front!

I'm fine with this.  I'll go for these names, and let someone else fix
it up if they care enough:

  system-file-name-convention
  file-name-separator?
  file-name-separator-string
  absolute-file-name?

> What about adding here a link to a page that describes “UNC”?

http://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx#fully_qualified_vs._relative_paths
is the link; will include it.

Thanks,

Andy

I pushed a fix that recognizes drive components and UNC file names as
absolute, and that attempts to allow for (and prefer) backslash as a
file name separator on Windows systems.

Is this necessary now that backslash is recognized as a file name
separator?  I did not apply this part yet.

Still working on the rest.

Yes, I think so.  I have a couple of comments, though:

A UNC file name can also begin with 2 slashes, as in "//foo/bar/".  In
general, Windows system calls treat both kinds of slashes identically.

Why is this transformation needed?  Native Windows system calls will
not understand "/c/foo" syntax.  What is this about?  (I know it was
in the original code, but I didn't understand it then, either.)

Possibly.  But are you sure there's no more references to '/' alone in
C code (as opposed to in Scheme)?

Hi Eli,

However iconv is specified
(http://pubs.opengroup.org/onlinepubs/009695399/functions/iconv.html) to
take a char** as the first argument.  Don't we end up using a GNU iconv
on mingw32 anyway?

It seems that gnulib handles this already, and this block is no longer
present in Guile source (since last January).

Likewise, this block is no longer present in Guile; we depend on Gnulib
for mkdir, and we have an explicit check for fchmod.

I assume this won't be needed for filesys.c, as it does not use
O_BINARY (any more?).

Gnulib's fcntl.h defines O_BINARY on all platforms already, so this
should be fixed already.

This seems like a bug to me, that the behavior of full_read can depend
on the incoming errno.  I mailed bug-gnulib and put you on copy to see
what they would say.

Applied, thanks.

Hummmmmmm.  It's true that the only user of mkstemp in Guile is the
compilation code.  OTOH it's a public interface, and this change might
affect someone.  OTOH MinGW is not well-served currently and probably
there are ~0 active users.  Any other thoughts here?

Surely we should just rely on Gnulib here and not include the winsock
headers.  In what condition would these headers be included otherwise?
A visual studio build or something?

Auto-compiling /foo/bar/baz.scm produces
$HOME/.cache/guile/2.0/ccache/foo/bar/baz.go.  This turns the drive
component into a path element on Windows so compiling C:/foo.scm caches
$HOME/.cache/guile/2.0/ccache/c/foo.go.

Yes, we do use GNU iconv.  However, the version of iconv.h (from GNU
iconv version 1.13, I think) that I have declares the function like
this:

  extern size_t iconv (iconv_t cd, const char* * inbuf, size_t *inbytesleft, char* * outbuf, size_t *outbytesleft);

As I wrote there, I suggest to add some application-level diagnostics
in this case, something like "premature end of file".

An alternative would be to provide a public interface to switch an
existing file descriptor to binary mode, and then use it from the code
that calls mkstemp to output what will eventually become a *.go file.

Sorry, I have no idea.  If relying on gnulib is OK for non-MinGW
Windows platforms (if there are such), then it's fine with me.

Thanks, I see the light now.  Perhaps consider adding a comment there
pointing to this use of the transformation.

In these files, `input' is a char*.  So &input should be a char**.
Shouldn't that cast to const char** without a warning?

You know, given that temporary files are for writing more than for
reading, it makes sense to just add the O_BINARY flag and be done with
it.  I'll do that.

I think for now this is the right thing.  It seems that even visual
studio builds are supported by gnulib, so the specs we code against
should either be posix or gnulib abstractions.  I have removed this #if
block.

Thanks,

Andy

Maybe it's some obscure bug my compiler.  If you can get away without
a warning in such situations, even when the prototype does specify
"const char **", then feel free to disregard these changes.  They are
certainly not Windows or MinGW specific.

I'm not trying to disregard your change, but the cast really shouldn't
be necessary.  Adding an explicit cast to (const char**) would start
causing warnings on platforms that have a posix iconv prototype, like
those with GNU libc.

So, very respectfully, I think I will not apply this one.

I've fixed this, I think.

I am pretty sure, yes.  I just pushed some patches to make sure this is
the case, altering load.c's logic to be more structurally similar to
boot-9.scm's and preferring backslashes on Windows.

So with these last commits, hopefully native MinGW builds are supported.
Would you mind testing again?  Please send a new mail to
bug-guile@gnu.org to track any new failures.

Thanks, and sorry for a long delay.

I tried today building Guile 2.0.9.  The C compilation went very
smoothly, with only a couple of warnings (one is the known iconv
prototype "issue", the other a variable that is set and not used).
However, once it got to compiling Scheme files, it repeatedly failed
after writing each .go file.  Here are a few typical failures:

       GEN      guile-procedures.texi
     Backtrace:
     In unknown file:
	?: 3 [apply-smob/1 #<boot-closure 234da60 (_ _ _)> #t ...]
	?: 2 [apply-smob/1 #<catch-closure 2e07050> quit #<unspecified>]
	?: 1 [apply-smob/1 #<boot-closure 234da60 (_ _ _)> #t ...]
	?: 0 [apply-smob/1 #<catch-closure 3f7eea0>]

     ERROR:

The program then sits at the ERROR: prompt, but does not accept any
input.

Seems that this comes from smob.c:

     static SCM
     scm_smob_trampoline (unsigned int nreq, unsigned int nopt,
			  unsigned int rest)
     {
       SCM trampoline;

       if (SCM_UNLIKELY (rest > 1 || nreq + nopt + rest > 3))
	 scm_out_of_range ("make-smob", scm_from_uint (nreq + nopt + rest));

       trampoline = SCM_SMOB_TRAMPOLINE (nreq, nopt, rest);

       if (SCM_LIKELY (SCM_UNPACK (trampoline)))
	 return trampoline;

       switch (nreq + nopt + rest)
	 {
	   /* The + 1 is for the smob itself.  */
	 case 0:
	   trampoline = scm_c_make_gsubr ("apply-smob/0", nreq + 1, nopt, rest,
					  apply_0);
	   break;
	 case 1:
	   trampoline = scm_c_make_gsubr ("apply-smob/1", nreq + 1, nopt, rest,
					  apply_1);

But I have no idea what it means.

When this happens, guile.exe still runs (actually, there are 2 Guile
processes, one a child of the other), so it is impossible to delete
guile-procedures.texi, because one of these processes holds it open.
I needed to kill guile.exe (the child) to be able to try again.

I tried "make -k" to see how far I can advance.  The next compilation
of ice-9/eval.scm then stops with the same error:

     make[2]: Entering directory `/d/usr/eli/utils/guile-2.0.9/module'
       GUILEC ice-9/eval.go
     wrote `ice-9/eval.go'
     Backtrace:

	?: 1 [apply-smob/1 #<boot-closure 26cca60 (_ _ _)> #t ...]

     ERROR:

     Backtrace:

     In ice-9/eval.scm:
      481: 0 [lp (#<fluid 12>) ((#<catch-closure 3ccb420>))]

     ice-9/eval.scm:481:19:

Any ideas?  Where should I look for the source of this problem?

TIA

Hi Eli :)

Thank you for your ongoing work on MinGW and Guile, it's really
appreciated.  I just wanted to say that explicitly here, even though I'm
closing this bug, as I understand that things have progressed a bit in
these 3 years; anyway.  Your work is so valuable to many users.  Thanks!

Andy

Thanks.

I would be happier, though, if the patch for open-process, whose last
version I submitted here:

  https://lists.gnu.org/archive/html/guile-devel/2014-08/msg00015.html

would be admitted to the repository, as it fixes important
functionality that is currently unavailable in the MinGW build with
upstream sources.  AFAIR, the last communication about this patch was
here:

  https://lists.gnu.org/archive/html/guile-devel/2014-08/msg00024.html
  https://lists.gnu.org/archive/html/guile-devel/2014-08/msg00041.html

I pinged about it a month later:

  https://lists.gnu.org/archive/html/guile-devel/2014-09/msg00066.html

but got no responses.

Let's give it a go!  I understand that you do not want to work with
gnulib.  That's a negative from a Guile POV -- but it's not a
deal-breaker.  The thing we like about Gnulib is that we like working
with POSIX abstractions as much as possible, and we find that it's
easier to do our work as Guile maintainers when we limit and reduce the
number of portability-related shims in our code.  To that end I hesitate
about including a bunch more stuff in posix.c.  Must it all be there, or
would it be possible to move some of it out to our own gnulib-like
mingw-w32.[ch] or something?

Andy

I have nothing against Gnulib, but in this case their solution is
simply not up to speed.

Most of it is already on a separate file, w32-proc.c (see the diffs).
I could take the macros at the beginning of posix.c and put them on a
separate .h file, if that would be better.  The rest of the changes in
posix.c are just moving #ifdef's around, more or less, and a few small
fragments of code, not unlike in other places.  I could, of course,
put them in separate functions, but the advantage of the patch I
pointed to is that it's well tested.

Thanks.

That would be great, if you'd be amenable.  Thanks!

Done and posted on guile-devel.

Thanks.
