Thanks.
BTW, I just noticed this in the GNU coding standards, 7.2.1 General
Conventions for Makefiles:
"Every Makefile should contain this line:
SHELL = /bin/sh
to avoid trouble on systems where the `SHELL' variable might be
inherited from the environment. (This is never a problem with GNU
`make'.)"
So Make programs differ in this, the current '$(SHELL) libtool' was
never supposed to be correct, and $CONFIG_SHELL concerns seem irrelevant.

Don't know. Since this is for a Unix-style Makefile, I expect it depends on Cygnus et al to compile system() and exec() in the Make program into library calls which handle '#!'. > If it's a problem, we can AC_SUBST(LT_SHELL) and use that (which will > cause problems for people not using automake, like yourself). Eh, right. Sounds like the shell should be inserted in the LIBTOOL definition itself then, without going via an LT_SHELL. Which in turn would prevent people from running libtool with another shell if the current shell breaks, if there is any reason to do that. -- Hallvard

If it's a problem, we can AC_SUBST(LT_SHELL) and use that (which will cause problems for people not using automake, like yourself). Peter

This is an old bug by now, but the reports I've seen do not seem to
get at all of it.
libtool.m4:LT_INIT says LIBTOOL='$(SHELL) $(top_builddir)/libtool'.
Gnu Make exports SHELL=/bin/sh. Maybe other Makes too, I do not know.
Thus even when a package is configured and built with the same $SHELL,
the libtool script can get run by another shell than it was built for.
This breaks when libtool is built as a bash script using '+=', but
$(SHELL) does not support '+='. In my case: Ubuntu's /bin/sh = dash.
Either the LIBTOOL= line should lose $(SHELL) so the #!<shell> line in
the libtool script takes effect, or it should use e.g. $(LT_SHELL)
which would be set to the shell which libtool was built for, or
libtool should exec itself with its desired shell. Users should not
have to set CONFIG_SHELL=/bin/sh.
This applies to at least libtoolize 2.4.2 and Ubuntu's patched 2.4.
I'm using aclocal 1.11.1, autoconf 2.68.
Here is a minimized example:
mkdir foo foo/m4
cd foo
echo 'int main() {return 0;}' > foo.c
cat <<'EOF' > Makefile.in
top_builddir = @top_builddir@
foo.o:; @LIBTOOL@ --mode=compile @CC@ -c foo.c
EOF
cat <<'EOF' > configure.ac
AC_INIT([foo])
AC_CONFIG_AUX_DIR([m4])
AC_CONFIG_MACRO_DIR([m4])
AC_PROG_CC
LT_INIT([disable-shared])
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
EOF
libtoolize --copy --install --quiet; aclocal -I m4; autoconf
./configure --quiet
cat Makefile; echo "libtool head == `head -1 libtool`"
make
Output:
top_builddir = .
foo.o:; $(SHELL) $(top_builddir)/libtool --mode=compile gcc -c foo.c
libtool head == #! /bin/bash
/bin/sh ./libtool --mode=compile gcc -c foo.c
eval: 1: base_compile+= gcc: not found
eval: 1: base_compile+= -c: not found
libtool: compile: you must specify a compilation command
libtool: compile: Try `libtool --help --mode=compile' for more information.
make: *** [foo.o] Error 1
Any advise as to what to do (other than staying with libtool 1.5)?
For now I use the simplest fix, removing $(SHELL). Or should
Makefile.in be using something else than @LIBTOOL@?
