bug#10520: [platform-testers] Guile 2.0.4 release imminent

[Bruno Haible]

Hi Ludo,

> Guile has the following dependencies:
> 
>   - libgmp 4.1+
>   - libiconv on non-GNU systems
>   - libintl on non-GNU systems
>   - libltdl (from GNU Libtool)
>   - libunistring
>   - libgc 7.x
>   - libffi

The build reports below are with
  gmp 5.0.2
  libiconv 1.14
  libintl 0.18.1.1
  libltdl 2.4.2
  libunistring 0.9.3
  gc 7.2alpha6
  libffi 3.0.10
  guile-2.0.3.152-c5f6c2

* gmp 5.0.2 has some configuration trouble on systems with recent
  coreutils utils installed. Could be worked around by setting NM=nm.
  It also has configuration trouble on bi-arch systems, that can be
  worked around by setting ABI=32.
  It also has configuration trouble on MacOS X 10.5 and mingw, that
  requires effort to work around.

* libintl 0.18.1.1 has configuration trouble on Solaris 11: must use
  --with-included-gettext, otherwise the gettext() function never actually
  returns the translations.

* libffi 3.0.10 has configuration trouble on OpenBSD, NetBSD, Solaris 11.
  Must use --disable-builddir as workaround.
  Also "make check" shows lots of test failures on Linux/SPARC64,
  NetBSD 5.1, Cygwin 1.7.9.

* gc 7.2alpha6 has compilation trouble and doesn't work reliably on
  NetBSD 5.1/x86 and on mingw.

Now about the configuration of guile itself.


1) On nearly all platforms, guile's configure does not find the libgc or
libffi library, although these packages were configured and installed
with the same --prefix as guile. The culprit is PKG_CONFIG_PATH.
guile's installation instruction don't mention it:

  - INSTALL doesn't mention PKG_CONFIG_PATH.

  - README mentions PKG_CONFIG_PATH only in the section "Using Guile
    Without Installing It", which is not my situation.

  - README's section "Required External Packages" mentions pkg-config,
    but it suggest to set BDW_GC_CFLAGS, BDW_GC_LIBS, LIBFFI_CFLAGS,
    LIBFFI_LIBS, which is even *more* complicated than setting
    PKG_CONFIG_PATH.

    How about changing that section to mention
      1) that pkg-config ought to be installed before libffi and libgc?
      2) that usually setting PKG_CONFIG_PATH to include
           $BDW_LIBDIR/pkgconfig:$LIBFFI_LIBDIR/pkgconfig:/usr/lib/pkgconfig
         will work,
      3) the BDW_GC_CFLAGS, BDW_GC_LIBS, LIBFFI_CFLAGS, LIBFFI_LIBS
         approach as a last resort.


2) On Linux/glibc/PowerPC, MacOS X 10.5, Cygwin, I happen not to have
pkg-config installed. But I have installed all the other packages!
The configuration fails:

checking for pkg-config... no
checking for LIBFFI... configure: error: in `/home/haible/multibuild-1614/linuxppc32/guile-2.0.3.152-c5f6c2':
configure: error: The pkg-config script could not be found or is too old.  Make sure it
is in your PATH or set the PKG_CONFIG environment variable to the full
path to pkg-config.

Isn't this a *gratuitous* build dependency?

Suggestion: Add code to configure.ac that searches for an installed
library, like it does for libgmp and libunistring (via
AC_LIB_HAVE_LINKFLAGS), before searching via pkg-config.

I won't install pkg-config. If you want me to test guile on Linux/PowerPC,
MacOS X 10.5, Cygwin, and mingw, provide an alternative.


3) On Solaris 11, the build fails:

$ make
...
Making all in libguile
make: Fatal error in reader: Makefile, line 3443: Macro assignment on dependency line
Current working directory /home/bruno/multibuild-1610/solaris11x8664/guile-2.0.3.152-c5f6c2/libguile
*** Error code 1

The line about which the Solaris 'make' is complaining is the blank line
between these two rules in libguile/Makefile:


.c.i:
        $(AM_V_GEN)$(GREP) '^VM_DEFINE' $< > $@

install-exec-hook:
        rm -f $(DESTDIR)$(bindir)/guile-snarf.awk
#    $(DOT_DOC_FILES) $(EXTRA_DOT_DOC_FILES) \
#    guile-procedures.txt guile.texi


The workaround is to use GNU make.


4) On Solaris 11 (both x86 and x86_64), the compilation fails in the
directory libguile:

  CC     libguile_2.0_la-filesys.lo
filesys.c: In function 'scm_readdir':
filesys.c:1716:34: error: 'DIR' has no member named 'dd_fd'
gmake[3]: *** [libguile_2.0_la-filesys.lo] Error 1

Instead of whacking your own implementation of dirfd, why not just
use the 'dirfd' module from gnulib? (Actually Solaris 11 has dirfd(),
it is declared as a function in <dirent.h>.) See
http://www.gnu.org/software/gnulib/manual/html_node/dirfd.html


5) On OpenBSD 4.6/SPARC64, compilation failure in libguile directory:

  CC     libguile_2.0_la-i18n.lo
i18n.c: In function `define_langinfo_items':
i18n.c:1747: error: `ERA' undeclared (first use in this function)
i18n.c:1747: error: (Each undeclared identifier is reported only once
i18n.c:1747: error: for each function it appears in.)
i18n.c:1748: error: `ERA_D_FMT' undeclared (first use in this function)
i18n.c:1749: error: `ERA_D_T_FMT' undeclared (first use in this function)
i18n.c:1751: error: `ERA_T_FMT' undeclared (first use in this function)
i18n.c:1753: error: `ALT_DIGITS' undeclared (first use in this function)
gmake[3]: *** [libguile_2.0_la-i18n.lo] Error 1

This could be easily fixed by including the gnulib module 'nl_langinfo'. See
http://www.gnu.org/software/gnulib/manual/html_node/nl_005flanginfo.html


6) On Linux/IA-64, compilation failure in libguile directory:

  CC     libguile_2.0_la-threads.lo
threads.c: In function 'guilify_self_1':
threads.c:554: error: 'struct GC_stack_base' has no member named 'reg'
make[3]: *** [libguile_2.0_la-threads.lo] Error 1

On this platform, gc/gc.h contains this definition:

/* Structure representing the base of a thread stack.  On most          */
/* platforms this contains just a single address.                       */
struct GC_stack_base {
  void * mem_base; /* Base of memory stack. */
# if defined(__ia64) || defined(__ia64__) || defined(_M_IA64)
    void * reg_base; /* Base of separate register stack. */
# endif
};

It looks like a typo in threads.c:554. Fix: s/reg-base/reg_base/


7) On NetBSD 5.1/x86_64, build failure:

Making all in module
  GUILEC ice-9/eval.go
GC Warning: Out of Memory! Heap size: 248 MiB. Returning NULL!
[1]   Segmentation fault (core dumped) GUILE_AUTO_COMPI...
*** Error code 139

What's the reason of an "Out of Memory"? The machine has 3 GB RAM, and
ca. 650 MB RAM and 6 GB of swap are free.


8) On Linux/hppa and Linux/SPARC32 and Linux/IA-64, build failure in the
libguile directory:

9) Test failure on Linux/glibc/i386 (32-bit build on a x86_64 machine):

FAIL: gc.test: gc: Lexical vars are collectable

10) Linux/glibc/x86_64

All tests passed.

(This must be the platform that all guile developers use, I guess?)

bug#10520: [platform-testers] Guile 2.0.4 release imminent

[Bruno Haible]

PS: More failures:

11) On Solaris 11, "make check" gives 1 test failure:

gmake[5]: Entering directory `/home/bruno/multibuild-1614/solaris11x8632/guile-2.0.3.152-c5f6c2/test-suite/standalone'

       tail [+/-[n][l][r|f]] [file]
Incorrect output: expected "a;", but got ""
FAIL: test-guile-snarf

The 'tail' program in Solaris does not understand the modern syntax.

$ printf 'a\nb\nc\nd\ne\n' | tail -n +2
usage: tail [+/-[n][lbc][f]] [file]
       tail [+/-[n][l][r|f]] [file]
$ printf 'a\nb\nc\nd\ne\n' | tail -n 2
usage: tail [+/-[n][lbc][f]] [file]
       tail [+/-[n][l][r|f]] [file]
$ printf 'a\nb\nc\nd\ne\n' | sed 1d

e

So I would suggest to replace "tail -n +2" with "sed 1d".

I’ve done something along these lines:

Isn’t this a gratuitous troll?  ;-)

Seriously, I understand your frustration.  Yet, we use upstream’s method
to check for package availability, whether we like it or not.

One can define $BDW_GC_LIB, etc. as described in the manual.  Would that
work for you?

Do you mean OpenIndiana or something?

Funnily, Solaris 2.10 (as available on the OpenCSW machines) doesn’t
have this problem.

I considered using it some time ago but decided not to, as the comment

   Note: We don't use Gnulib's `nl_langinfo' module because it's currently not
   as complete as the compatibility hacks in `i18n.scm'.  */

I reproduced the problem on SPARC64 and am investigating (2.0.1 works

Hi Ludo,

Another set of platforms is being tested right now.

About configuration of the dependencies:

Hmm, two comments about your advice
  PKG_CONFIG_PATH=/path/to/libgc/lib/pkgconfig:/path/to/libffi/lib/pkgconfig

- When the packages are installed on a bi-arch system, in $prefix/lib64/
  (or, on Solaris, $prefix/lib/64/), then the pkgconfig dir is a subdir
  of that directory. More precisely, if the package was installed with
  --libdir=$LIBFFI_LIBDIR, then the dir to use is $LIBFFI_LIBDIR/pkgconfig.

- If the user sets this variable and then forgets about it, and it does not
  contain /usr/lib/pkgconfig or /usr/lib64/pkgconfig, then AFAIU other
  packages installed in /usr/lib[64] will no longer be found.

Given the size of the thread about this topic in gnu-prog-discuss, it
is not gratuitous to talk about it.

You can do better than that.

This is even more work, no thanks.

I mean, after I installed the prerequisite packages with the same --prefix,
guile found libiconv, libintl, libunistring, libgmp all automatically,
without any further ado - because you are using the gnulib module 'havelib'.
For packages as simple as libffi and gc, these macros will work as well.

Can't you just change 

  PKG_CHECK_MODULES(LIBFFI, libffi)

to

  AC_LIB_HAVE_LINKFLAGS([ffi],
    [],
    [#include <ffi.h>
     #include <stdlib.h>],
    [ffi_call (NULL, NULL, NULL, NULL);])
  if test "$HAVE_LIBFFI" = yes; then
    LIBFFI_CFLAGS=          # CPPFLAGS already augmented

and similarly for libgc.

If this gets too complicated, I can extend the gnulib 'havelib' module to
also invoke pkg-config when the search in the various directories failed.

No, I meant Oracle Solaris 11, released on 2011-11-09. Cf.
http://en.wikipedia.org/wiki/Solaris_(operating_system)
http://www.oracle.com/technetwork/server-storage/solaris11/downloads/index.html

But I warn you: with this OS, before you have a usable system,
you have to learn how to use their package manager. Otherwise,
no gcc, no development tools.

If you are not satisfied with the contents of a particular gnulib module,
please by all means say so on the bug-gnulib list. I beg you. Then the
enhancements will not only profit guile but also other packages.

Then, why not change the test so that it only prints a warning message,
and always succeeds?

I know, I know.  I really view README as a hint, in the hope that the
user will understand that /path/to/libgc/lib/pkgconfig will have to be
replaced by the correct file name.  I don’t think another convention,
such as writing $LIBFFI_LIBDIR, really helps.

The problem we could run into, by not using libffi’s and BDW-GC’s
recommended methods, is that we could miss CFLAGS, CPPFLAGS, or LDFLAGS
that appear in their .pc files.

Thus, it seems more robust to configure these packages the way they are
meant to be configured, rather than do our own guesswork.

WDYT?

Perhaps the pkg-config discussion should actually be moved to bug-gnulib
or bug-standards, because it’s beyond Guile’s scope.

Hmm, OK, noted!

Yes, sure.  It turns out that i18n.{c,scm} in Guile predate the
‘langinfo’ module in Gnulib, and Guile’s needs may be different than
those of other packages.

Actually, I have a stash here to do that (see below), but I can’t
remember why I didn’t apply it.  I’ll try again and report back.

This is being discussed elsewhere:

I bisected this and found this harmless-looking patch to be the culprit:

  http://git.savannah.gnu.org/cgit/guile.git/commit/?id=3e54fdfc217969abb50a46ec9c9c5c02a2c7d369

The segfault would occur in vm-i-system.c:1281, in the ‘CACHE_PROGRAM’
macro, while trying to access ‘SCM_PROGRAM_DATA’, because of a bogus
value for ‘program’, stemming from a bogus ‘fp’.

After a long and tiring period of investigation, I found that reverting
just the definitions SCM_FRAME_DYNAMIC_LINK and
SCM_FRAME_SET_DYNAMIC_LINK would solve the problem.

Eventually, I found that, keeping frames.h unchanged, adding a compiler
barrier after each ‘fp’ assignment would solve the problem:

This is not entirely satisfactory either, because I don’t see why this
barrier would be needed.  It could be a GCC bug, as this file is a real
stress test.  Ideas?

Unless someone comes up with a better idea, I’ll commit a portable
version of the above patch.

(Tested on sparc64-unknown-linux-gnu and hppa2.0-unknown-linux-gnu.)

Thanks,
Ludo’.

I’ve checked this in:

  http://git.sv.gnu.org/cgit/guile.git/commit/?h=stable-2.0&id=2b264d7e4fb649955ade1814527b6eb6f34f4e18

Closing the bug, because I think bugs were all addressed.  Let us know
if you think I got it wrong!

Thanks,

Hello,

For the record, compiling with -fno-strict-aliasing solves the problem
too, and possibly other similar issues, so we took that route for the
moment (commit f5ea0499a411309014475dc7f7983e827f431af2).

Thanks,

Hi,
 	I've tested this 2.0.4 release candidate on powerpc-darwin8, and 
the results look pretty good.  (Even a bug list needs good news, right?) 
Attached is a complete build and test log, if you're curious about the few 
test failures (nothing new, not regressions).  Looking forward to the 
release!

Thanks for the report!  As we seem to be following these issues over at
bug 10684, I'll close this one.  Let me know if that was the wrong thing
to do.

Cheers,
