There was a recent discussion about these sorts of builds at

If I understand this correctly, the proposed way for cross
compilation is to build the code generators (like gen-scmconfig)
entirely using the build toolchain. This means that <uniconv.h>
and others have to be available on the build system, and constants
are taken from there, rather than from the host toolchain.

In other words, cross-compiling will only work well if the
library versions of the build toolchain and the host toolchain
don't differ too much.

Is this really the way this is meant to be done?

Please don't take this is as a harsh criticism. I just want to
make sure that I fully understand this advice.


Greets,
Volker

Yes, I think this is a bug in gen-scmconfig, as you (?) reported long
ago.

Guile with win32 cross compiling

[Volker Grabsch]

[-- Attachment #1: Type: text/plain, Size: 1169 bytes --]

Hello Mike,

I just tried again to cross compile a win32 version of guile, using
the latest 2.0.0 release. My last attempt in April 2010 failed.

Much has been improved since then, but there are still fatal
errors, so I still can't support guile-2 in mingw-cross-env. [1]


1)

The first issue is the "#include <uniconv.h>" in gen-scmconfig,
which has already been discussed in the past and for which I
already provided a clean, working solution. I forward-ported
my patch to guile-2.0.0 and it seems to work. This patch is
attached to this email, please consider applying it.

Also attached is a build log created by mingw-cross-env showing
how far the cross build gets with this patch.


2)

The other open issue is also a known one: the missing mmap()
function under Windows. After some research, I found a promising
mmap()/munmap() implementation for Windows in a free software
project:

http://code.google.com/p/flvmeta/source/browse/trunk/src/mmap.h?r=74
http://code.google.com/p/flvmeta/source/browse/trunk/src/mmap.c?r=74

Maybe this is worth integrating into guile?



Greets,
Volker

I don't know what discussion you are referring to here; best to link.

In any case, I don't understand the mechanism here, but I believe the
point was to make it so that #include <libguile.h> would not pull in
iconv headers.  gen-scmconfig looks up the value of the constants for
iconv conversion handlers, and writes them into scmconfig.h.  Your patch
undoes that.

What problem are you working around here?

You know, not only do we not rely on MAP_SHARED -- I switched it to use
PRIVATE, just now -- we didn't actually need mmap at all.  I just
changed it to use read(2) if mmap is not available, and it seems to work
fine, just a little (5-10%) slower to start up.  That should help our
unfortunate friends working on Windows :)

I'm referring to:

    "Portability fixes for win32 cross compiling"
    http://www.mail-archive.com/guile-devel@gnu.org/msg05308.html

The problem is that this mechanism works completely against the
nature of cross compiling.

The issue exists in all attempts to cross compile guile, but they
become extreme when cross compiling on a Unix system for MinGW,
as those systems are very different.

Gen-scmconfig is a code generator, so it has to be built using
the native toolchain. However, it is supposed to write take its
values from the <uniconv.h> of the cross tool chain. Thus, the
"/usr/include" equivalent of the cross tool chain is added to
the include path when compiling gen-scmconfig. And here the
trouble starts, because mixing headers of various toolchains
is never a good idea. Among others, basic headers like <stdio.h>
are now taken from the cross toolchain, referring to objects that
don't even exist in the native toolchain, causing the build to
fail with all kinds of strange error messages.

That's good news. Maybe this will enable me to include the next guile
release in mingw-cross-env - a project dedicated to all those unfortunate
friends. :-)  Using mingw-cross-env and Wine, they at least don't have
to actually run Windows just to build and test their project's Windows
port. ;-)

Ah yes.  Thanks for that link.  And thank you for your ongoing patience

Hmmm.  Well.  We have other code generators in Guile's build system;
notably the configure script (via config.h and other output files).
What do folks think about the attached patch?

Andy

Subject: [PATCH] check for iconveh values at configure-time

* configure.ac: Check for the iconveh values here, instead of relying on
  gen-scmconfig to know them.  That doesn't work in general because
  gen-scmconfig runs on the build machine, not the target machine.

* libguile/Makefile.am (gen-scmconfig.$(OBJEXT)): Revert rule to the
  revision before 533d8212.

* libguile/gen-scmconfig.h.in (SCM_I_GSC_ICONVEH_ERROR):
  (SCM_I_GSC_ICONVEH_QUESTION_MARK):
  (SCM_I_GSC_ICONVEH_ESCAPE_SEQUENCE):
* libguile/gen-scmconfig.c: Use configure-time substitutions to set
  SCM_ICONVEH_ERROR_HANDLER et al.

Please drop me a note when you want me to check your patch,
confirming that your work really solves the win32 cross issues.

I already tried to check this patch, but I wasn't able to find
out which version it is meant to be applied to.

Hmm, it should have applied to stable-2.0.  I can commit it if there are
no objections, as there do not appear to be.  It should fix the
gen-scmconfig issue.

Okay, so I give it another try.

    git clone http://git.savannah.gnu.org/r/guile.git -b stable-2.0
    cd guile

It seems that your patch is already in there, so no "patch" command
is needed after "git clone". Next steps are autogen/configure/make.
The whole configure command is a bit longer, because unfortunately
we have to tweak some stuff to make it really cross-compile:

   ./autogen.sh
   ./configure --host=i686-pc-mingw32 --disable-shared --without-threads scm_cv_struct_timespec=no LIBS='-lunistring -lintl -liconv'
   make

Explanation:

   "--without-threads" is needed because threading is a difficult
   issue that I'd like to deal later with.

   "scm_cv_struct_timespec=no" is needed to ensure that libguile/threads.c
   won't try to use the "struct timespec" from <pthreads.h>, which
   would fail because we don't use pthreads (yet). I think this should
   better be fixed in the source, but this workaround does the trick for now.

   "LIBS='-lunistring -lintl -liconv'" is needed because otherwise,
   the detection of libunistring fails. I think this should better
   be fixed in configure.ac, but this workaround does the trick for now.

In addition, I had to fix two other things in the source. The patches
are attached to this email:

    "fix-include-error-in-gen-scmconfig.patch"
    The patch re-introduces a change which I already proposed
    in my last patch: You can't use $(AM_CPPFLAGS) for the native
    build, because it adds "-I../lib" which means that <stdio.h>
    is taken from the local GNU-lib installation. The problem is
    that the GNU-lib in "lib/" has been configured for MinGW, not
    for the native system. So it performs some fixes which don't
    work on non-MinGW systems, leading to strange, unhelpful error
    messages. It took me quite some time to figure this out, mostly
    because I thought that this should have already been fixed.

    "remove-mingw-ifsock.patch"
    This patch fixes an issue that also appears on native MinGW
    build, because _S_IFSOCK simply isn't defined there. Note that
    this issue was already reported, but hasn't been fixed up to
    now, at least not in the stable-2.0 branch:
    http://lists.gnu.org/archive/html/guile-devel/2011-01/msg00183.html

After those changes, the build continues quite far, but ultimately
fails at the following position:

Hmmmm!  Yes, sorry for overlooking this part of your patch.  After
thinking for a while about it I agree with you.  I modified your patch
to add a comment.

If your target does not have e.g. struct addrinfo, because it does not
have IPv6, then you need to configure with
ac_cv_type_struct_addrinfo=no.  Check your config.log.  Or should this
be working somehow?

There are other ac_cv_* for getaddrinfo and other routines.

Happy hacking,

Andy

Okay, so I'm trying to get along without this ugly "ac_cv_type_struct_addrinfo"
hack, hoping that the following error report will be more useful to you.


1) My first attempt is to enable threads via:

   ./configure --host=i686-pc-mingw32 --disable-shared --with-threads LIBS='-lunistring -lintl -liconv'

This leads to the attached (compressed) config.log:

    config.log.with-threads.bz2

Make stops at this point:

---------------------------------------------------------------



2) My second attempt is to build without threading:

This leads to a slightly different config.log which I also attached:

    config.log.without-threads.bz2

Make then stops at the same point with just a few less error messages:

---------------------------------------------------------------


I ran builds builds from a clean Git checkout of commit
"19761af161942ef18aa2b7891cbf718fc5be5945" of the stable-2.0 branch.


Note that I would of course prefer a thread-supporting build of Guile,
but the problem is that "libgc" refuses to build under MinGW with
Pthreads, so I had to build libgc with "--enable-threads=win32".

On the other hand, it seems that Guile assumes "libgc" to be built
with "--enable-threads=pthreads".

I'm not sure whether this should be fixed in libgc or in Guile.
Nevertheless, this only accounts for half of the issues, as Guile
also fails to build without threading suppport (--without-threads).

As a final note, I'm using the "Pthreads-w32" library to provide
pthread support under MinGW.  (http://sourceware.org/pthreads-win32/)

Thanks for pointing me to this project. This looks really
promising and I would be glad for learning from that.

1) The pthread issue

As far as I can see, you have patched libgc to support pthreads
under MinGW. You forward-ported those patches from libgc-6.8 to 7.2,
so I'm wondering why those patches didn't make it into upstream
(i.e. the official libgc project) during that time. Are there any
issues with those patches that I should know about?

Also, have you actually offered these patches to upstream? If so,
what's the URL to their bug tracker, or mailing list archive, where
this issue has been discussed? I haven't been able to find any such
information in neither the *.py file not the patch files.

2) The struct_timespec / ipv6 / etc. issues

It seems that you solve those issues using an even uglier hack
than I did. I'm wondering why it is necessary to manipulate the
config.cache, as providing those variables as ./configure paramters
worked quite well for me.

Moreover, is this a sensible thing to do anyway? Shouldn't we try
to fix the configure.ac to make it more portable and to make it
properly detect those MinGW things in the first place?

FWIW there should be a new libgc tarball out, if not now, then within
the next few days.

The libgc list is gc@linux.hpl.hp.com.  I have found the libgc
maintainers to be very responsive.  If there is a problem with mingw and
threads that is fixed by Jan's patches, I'm sure they would be happy to
have them.  Who will submit them there, Jan or Volker?

I have not looked at the patch, and am away from the internet at the
moment, but patching config.cache isn't really a bad thing, AFAIU.

Here's the deal.  Configure scripts attempt to figure out what features
your system supports by doing configure-time feature checks (not
platform checks).  But if you are cross-compiling, sometimes it doesn't
have all of the information that it needs.  In that case, the configure
script will make an assumption.  When that assumption does not hold for
you, you need to midify the assumption that it's going to make, by
setting a cache variable.

You can set a cache variable on the ./configure command line, or set it
in a config.cache or config.site file.  It doesn't matter which.  In
fact config.site is often the nicest solution, as you don't have to muck
up all of your ./configure invocations.

Hope this helps,

I submitted that patch; we'll see.

Looks good to me.  Could you factor it into an M4 macro, use
AC_CACHE_CHECK, and move that to acinclude.m4?

Thanks!

I tried and failed, so I pushed it anyway.  Would you like to do the
refactoring as a separate commit? :-))  Sorry for being pathetic here
but it is beyond my autofoo.

Cheers,

Guile with win32 cross compiling

[Volker Grabsch]

Hello Mike,

I just tried again to cross compile a win32 version of guile, using
the latest 2.0.0 release. My last attempt in April 2010 failed.

Much has been improved since then, but there are still fatal
errors, so I still can't support guile-2 in mingw-cross-env. [1]


1)

The first issue is the "#include <uniconv.h>" in gen-scmconfig,
which has already been discussed in the past and for which I
already provided a clean, working solution. I forward-ported
my patch to guile-2.0.0 and it seems to work. This patch is
attached to this email, please consider applying it.

Also attached is a build log created by mingw-cross-env showing
how far the cross build gets with this patch.


2)

The other open issue is also a known one: the missing mmap()
function under Windows. After some research, I found a promising
mmap()/munmap() implementation for Windows in a free software
project:

http://code.google.com/p/flvmeta/source/browse/trunk/src/mmap.h?r=74
http://code.google.com/p/flvmeta/source/browse/trunk/src/mmap.c?r=74

Maybe this is worth integrating into guile?



Greets,
Volker
