bug#7995: Guile support in Automake
[ http://debbugs.gnu.org/cgi/bugreport.cgi?bug=7995 aka http://thread.gmane.org/gmane.comp.sysutils.automake.bugs/5303 ] * Ralf Wildenhues wrote on Sun, Feb 06, 2011 at 11:22:57PM CET: Automake should support Guile. I actually have patches for some tests, documentation and half an implementation from last year; Here we go. For now I've done little with the patches except rebase and squash the intermediate stages, update copyright years, remove notes from git, and ensure there are no syntax errors. That means however, that nothing really works yet. It's still a total mess. So what I would like to ask from readers at this point is: please go through the doc changes and let's discuss them first. Also, it is important to not step on guile/meta/guile.m4 toes (or vice versa), so some checking for that is prodent. When we know what is desired, the tests should be amended/fixed to cover that, and then we can fix the implementation to follow. If you prefer, I can also put them in a temporary branch (which for the moment I would expect to be rewound at some point later). Here's a preliminary list of issues that I see: - Why guile_GUILE and not guile_LISP? What's the rationale for naming it differently, and what's the rationale for actually treating it differently? This question has two parts: LISP is treated by emacs not guile-tools, and IIUC then the idea was that GUILE is compiled already at 'make all' time and not just at 'make install' time, right? Is the latter part just nice to have or an important feature? - The current tests assume _GUILE sources are distributed by default; OTOH, _LISP are not. Rationale for this semantic difference? - Please fix errors you can find in the tests; esp. the extension module in guile3.test doesn't seem to do the right thing yet (with my unfinished implementation). - I renamed guileextensiondir from earlier suggestions to guileextdir, both for brevity, and to avoid the question of whether there is a trailing 's' in the name. OK? - The Guile manual documents Autoconf macros distributed in $datarootdir/aclocal/guile.m4. The names in there are a bit unfortunate in that the macros more or less use the same GUILE_* namespace that we would like to use for some variables (which means you cannot easily turn on checking for unexpanded macro names through something like m4_pattern_forbid([^GUILE_])dnl and there is even overlap in the semantics and shell variable names. We need to address that; esp. since the macros shipped with Guile have been out there for long, we cannot just expect them to disappear instantly. There should be a clear, backward-compatible upgrade path, and a clear intent on how usage should be in the future, for Guile users both with and without Automake. - The handling of compile and link flags is still quite suboptimal. I still need to think about that a bit more. - I haven't yet considered the handling of flags to uninstalled module stuff. This is just TODO. - My current plan is to either not provide something like foo_scm_GUILEFLAGS = override for $(AM_GUILEFLAGS) or to not let it cause renamed .go files. Do you think users will need per-target guile-tools compile flags? Because if they do, then we need to document this stuff, and that it's not in line with how Automake operates elsewhere, etc. - The register_language bits in the last patch are totally unused yet, as the machinery isn't yet able to handle languages that either don't use a linker in the end, or don't rename objects with per-target flags which is probably desirable for Guile (similar to how Python support works). I should apologize for taking totally random and unorganized notes below. They are basically just a jot-down from last year of what Andy and Ludo said. Thanks, Ralf Notes about Guile support: # set from guile-config # or from pkg-config if guile major version known .go: compiled guile files sys-dep not executable byte-code .scm: source guile files (can have other extensions) .sls .sps .ss One problem will be: when we add Go support, .go has conflicting semantics. cat Makefile.am \END guile_GUILE = compiled-and-installed.scm nodist_guile_GUILE = not-distributed.scm guile_DATA = not-compiled.scm noinst_GUILE = compiled-but-not-installed.scm dist_noinst_DATA = just-distributed-blob.scm # object files will be installed in respective subdir of guileexecdir. nobase_guile_GUILE = installed-in-subdir/foo.scm pkgguile_GUILE = installed-in-package-dir.scm END # without guile compiler, just install sources # but also install objects whenever possible GUILE_TOOLS = guile-tools GUILE_TOOLS_COMPILE = $(GUILE_TOOLS) compile GUILE_COMPILE = $(GUILE_TOOLS_COMPILE) $(AM_GUILEFLAGS) $(GUILEFLAGS) $(GUILE_TOOLS_COMPILE) $(AM_GUILEFLAGS) $(GUILEFLAGS) -o $@ $ # no ordering req # no renaming foo_scm_GUILEFLAGS should not cause the output to be renamed.

+
+Automake provides support for compiled Guile source files with the
+@code{GUILE} primary as well as for installation of extensions modules
+for Guile in a compiled language such as C. A typical setup is to call
+@code{AM_PATH_GUILE} in @file{configure.ac} and use a line like the
+following in @file{Makefile.am}:
+
+@example
+guile_GUILE = foo.scm bar.sls baz.sps zork.ss
+@end example
+
+Here's a longer example with different types of file handling:
+
+@example
+guile_GUILE = compiled-and-installed.scm
+nodist_guile_GUILE = not-distributed.scm
+guile_DATA = not-compiled.scm
+noinst_GUILE = compiled-but-not-installed.scm
+dist_noinst_DATA = just-distributed-blob.scm
+
+# object files will be installed in respective subdir of guileexecdir.
+nobase_guile_GUILE = installed-in-subdir/foo.scm
+
+pkgguile_GUILE = installed-in-package-dir.scm
+@end example
+
+Here's an example of a typical extension module written in C:
+
+@example
+guileext_LTLIBRARIES = foo.la
+foo_la_SOURCES = foo.c
+foo_la_LDFLAGS = -module -avoid-version
+foo_la_LIBADD = $(GUILELIBS)
+AM_CFLAGS = $(GUILECFLAGS)
+AM_CPPFLAGS = $(GUILECPPFLAGS)
+@end example
+
+When @samp{AM_PATH_GUILE} is used, the suffixes @file{.scm}, @file{.sls},
+@file{.sps}, and @file{.ss} are assumed to be Guile sources, and
+compiled files will carry the @file{.go} extension.
+
+Any files listed in a @code{_GUILE} variable will be byte-compiled
+with @command{guile-tools compile} if that is available and new enough
+to compile Guile sources.
+
+Automake ships with an Autoconf macro called @code{AM_PATH_GUILE}
+that will determine some Guile-related directory variables (see
+below). If you have called @code{AM_PATH_GUILE} from
+@file{configure.ac}, then you may use the variables
+@code{guile_GUILE} or @code{pkgguile_GUILE} to list Guile source
+files in your @file{Makefile.am}, depending on where you want your files
+installed (see the definitions of @code{guiledir} and
+@code{pkgguiledir} below).
+
+@defmac AM_PATH_GUILE (@ovar{version}, @ovar{action-if-found}, @
+ @ovar{action-if-not-found})
+
+Search for a Guile compiler @samp{guile-tools compile} on the system.
+This macro takes three optional arguments. The first argument, if
+present, is the minimum version of Guile required for this package:
+@code{AM_PATH_GUILE} will skip any Guile interpreter that is older than

Re: [PATCH] {maint} tests: tempdirs with restrictive permissions are cleaned correctly
Hi Stefano,
sorry for the silence, I've been traveling. My plan is to do slowly but
steady catchup over the next week(end)s ...

please don't remove the quoting from the ! here. It exists to
facilitate copy and pasting commands from make output to the command
line, so even if it's not needed inside scripts, it is good defensive
coding to have it there too.
Also, it would seem that this issue is present in lib/am/distdir.am
as well. Care to address that (in another patch, if you like)?
Thanks,

Re: debbugs, and a FAQ, for Autotools
Hello everyone, * Ralf Wildenhues wrote on Sun, Feb 13, 2011 at 07:12:02PM CET: 2) Autotools should have a FAQ document. I've done a brain dump now, here's a rough initial version: http://www.gnu.org/software/automake/faq/autotools-faq.html and http://www.gnu.org/software/automake/faq/autotools-faq.texi (the former is generated from the latter via the Makefile). It is all incomplete, buggy, partly ugly, probably missing gnulib and gettext references in places, and everything, but I would like something to point users to now. Should all be reformulated nicely eventually ... I'd be happy about feedback, help, anything. For now there are several more questions than answers, and there are certainly many more questions that you can think of, so please write them. I don't actually care about the license, as long as we can move text between FAQ and manuals without too much hassle. Thanks, Ralf

Hi,
I'm not in autoconf debugging mode atm, so i'll have to ask more detailed
things some other time.
Looking through a ./configure script, i see lots of things being done
with file descriptors 5 and 6. What is going on here? eg:
## ##
## Autoconf initialization. ##
## ##
# ac_fn_c_try_compile LINENO
# --
# Try to compile conftest.$ac_ext, and return whether this succeeded.
ac_fn_c_try_compile ()
{
as_lineno=${as_lineno-$1} as_lineno_stack=as_lineno_stack=$as_lineno_stack
rm -f conftest.$ac_objext
if { { ac_try=$ac_compile
case (($ac_try in
*\* | *\`* | *\\*) ac_try_echo=\$ac_try;;
*) ac_try_echo=$ac_try;;
esac
eval ac_try_echo=\\$as_me:${as_lineno-$LINENO}: $ac_try_echo\
$as_echo $ac_try_echo; } 5
(eval $ac_compile) 2conftest.err
ac_status=$?
if test -s conftest.err; then
grep -v '^ *+' conftest.err conftest.er1
cat conftest.er1 5
mv -f conftest.er1 conftest.err
fi
$as_echo $as_me:${as_lineno-$LINENO}: \$? = $ac_status 5
test $ac_status = 0; } {
test -z $ac_c_werror_flag ||
test ! -s conftest.err
} test -s conftest.$ac_objext; then :
ac_retval=0
else
$as_echo $as_me: failed program was: 5
sed 's/^/| /' conftest.$ac_ext 5
ac_retval=1
fi
eval $as_lineno_stack; test x$as_lineno_stack = x { as_lineno=; unset

Re: about what goes into a distribution file
Hi Vincent, * Vincent Torri wrote on Fri, Feb 18, 2011 at 08:33:01AM CET: from the automake documentation, all the files read by AC_CONFIG_FILES are added in the distribution. But why aren't the generated files not in the tarball (the .pc.in are in but not the .pc for example) ? Just to answer the question for whoever else stumbles over this: because the point of generating them is that they may look differently on different systems. Thus it makes no sense to distribute them. And actually, the rules are a bit more complicated: the .in files are distributed only if they are mentioned literally in configure.ac (i.e., not as shell variable), and when they are not the output file of another AC_CONFIG_FILES command (e.g., foo.in.in - foo.in - foo). The gory details are documented here: http://www.gnu.org/software/automake/manual/html_node/Requirements.html Cheers, Ralf
Re: dynamic executables for check_PROGRAMS?
Hello Jeff, * Daily, Jeff A wrote on Fri, Feb 18, 2011 at 12:06:13AM CET: I wrote a profiling layer for my library utilizing weak symbols. I thought for starters it would be nice to profile some of my test programs, to make sure things are working okay. I'm using autoconf, automake, and libtool, so I configured using --enable-shared --disable-static, however, my test programs are not created as dynamic executables. I'm not sure I understand this. Programs are typically not created differently based on whether they are check_PROGRAMS or bin_PROGRAMS. Maybe you are thinking of uninstalled libraries which those programs depend on and which are noinst_LTLIBRARIES thus only generated as convenience archives? Here's how you can let them be shared libraries: noinst_LTLIBRARIES = libtesthelper.la libtesthelper_la_LDFLAGS = -rpath /nowhere The actual path you specify is not important, except that it should not be world-accessible because the system might try to find files there. If I have misunderstood your question, the maybe it helps to show a small example? Thanks, Ralf
