`info libtool "Tags"` describes them as a language that libtool supports
for the LT_LANG macro, alongside (in the version I'm using) C, C++,
Java, Fortran and Go. LT_LANG([Windows Resource]) does check for a
resource compiler named i686-w64-mingw32-windres or similar, and puts
it in the output variable RC; it's the intended steps after that that
are less clear.

The bug that I'm replying to (#25914) is a libtool enhancement request
asking for the way this is meant to work to be documented (including
whether it is meant to involve adding additional rules, and if so, what
those rules should typically be).
I am not a Windows developer (although I co-maintain dbus, which is
portable to Windows) so unfortunately I don't have a correct answer for
that, only anecdotal evidence based on what did and didn't work in dbus.

anything built-in for .rc files - at least, strings(1) shows me the rules
I'd expect to be built in (.c, .cc and so on) but doesn't mention .rc.

After invoking LT_LANG([Windows Resource]) in configure.ac, is the
Automake-generated build system meant to support compiling .rc files to
.lo and/or .o? I would expect that it should, but perhaps that expectation
is wrong?

After invoking LT_LANG([Windows Resource]) in configure.ac, is the
Automake-generated build system meant to support compiling .rc files to
.lo and/or .o? I would expect that it should, but perhaps that expectation
is wrong?
Thanks,

I do not see any described support for Windows resource files in the Automake manual at https://www.gnu.org/software/automake/manual/automake.html or the Autoconf manual at https://www.gnu.org/software/autoconf/manual/autoconf.html. What causes you to believe that there is support for a 'Windows Resource' language or specific support for Windows resource files? The good news is that specific support is not required since it is easy to add additional tests to configure scripts and additional rules to Automake makefiles.

This came up during maintenance of dbus,
<https://bugs.freedesktop.org/show_bug.cgi?id=103015>. We have a resource
(versioninfo.rc) that we want to link into a libtool library, and also a
resource (disable-uac.rc) that we want to link into an executable.
For the libtool library, what Reuben said works: libtool knows how to
"compile" resource files into Libtool objects, but Automake does not
provide a .rc.lo implicit rule automatically, so we have to provide
our own. It wasn't clear to me whether this should result in an Automake
feature request (to provide such a rule automatically), or whether that
should be a Libtool feature request, or whether this is all working as
intended and users of this facility are expected to provide their own
implicit rule as Reuben did. For the moment we've done the same thing
Reuben suggested:
--------
SUFFIXES = .rc
.rc.lo:
$(LIBTOOL) $(AM_V_lt) --tag=RC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=compile $(RC) $< -o $@
libdbus_1_la_SOURCES += versioninfo.rc
--------
For the executable, I found that I had to request compilation of a plain
object (.o) not a Libtool object (.lo), otherwise Automake 1.15.1
wouldn't realise that having $basename.rc in executable_SOURCES meant it
should include the corresponding $basename.o in executable_OBJECTS. This
worked with Debian's libtool 2.4.6-2 and Automake 1:1.15.1-3:
--------
SUFFIXES = .rc
.rc.o:
$(LIBTOOL) $(AM_V_lt) --tag=RC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=compile $(RC) $< -o $@
nodist_dbus_update_activation_environment_SOURCES += disable-uac.rc
--------
However, another developer found that with an older libtool (openSUSE's
libtool 2.4.2-18.3.1 and automake 1.13.4-8.9), and that same make rule,
libtool/Automake would output the .o file in .libs/$basename.o but then
try to link $basename.o (without .libs) into the executable, causing a
build failure. Unfortunately, I wasn't able to find a git commit between
2.4.2 and 2.4.6 that looked like it fixed this. So we ended up with this
rule instead, using plain windres instead of libtool when linking the
resulting object into an executable:
--------
SUFFIXES = .rc
.rc.o:
$(RC) $< -o $@
nodist_dbus_update_activation_environment_SOURCES += disable-uac.rc
--------
I would appreciate feedback from libtool developers on how much of this is
working as intended, and how much of it is a bug in either Automake or
libtool.
Thanks,
