Bug 396579 – sys-devel/libtool has #!/bin/bash yet uses $(SHELL) to call it

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Michał Górny 2011-12-31 10:34:46 UTC]

/usr/share/aclocal/libtool.m4:
	# Always use our own libtool.
	LIBTOOL='$(SHELL) $(top_builddir)/libtool'
	AC_SUBST(LIBTOOL)dnl

where SHELL defaults to /bin/sh, and /usr/bin/libtool installed to package has #!/bin/bash.

This is triggered, for example, in dev-libs/libtar.

[Comment 1 Rafał Mużyło 2011-12-31 16:36:02 UTC]

The catch lies most likely in one of ltmain.sh lines:
: ${SHELL="${CONFIG_SHELL-/bin/sh}"}

/usr/bin/libtool inherits its shell from PMS - it's one that was used at the time of generation.

if your /bin/sh sucks, then autoconf should have detected that and used /bin/bash.  so why didn't libtar do that ?

[Comment 3 SpanKY 2013-01-14 18:34:18 UTC]

please post a full build log showing the problem.  libtar seems to work for me.

$ ls -l /bin/sh
lrwxrwxrwx 1 root root 4 Jan 14 13:36 /bin/sh -> dash

$ ebuild libtar-1.2.11-r5.ebuild clean unpack prepare configure compile
...
/bin/bash ../libtool --mode=compile x86_64-pc-linux-gnu-gcc -O2 -march=amdfam10 -pipe -g -Wimplicit-function-declaration -I. -I.. -I. -I../compat -I../listhash -DCPPFLAGS_TEST -c -o append.lo append.c

I can reproduce it with -r4, the version which was in gx86 one year ago, when this bug was filed.

libtar r5 includes a lot of patches to the build system.  they have their own hand written Makefile.in instead of using automake.

if the only package you can hit this problem with is libtar and it doesn't use automake, then i don't think it's worth investigating.  i don't see a bug w/libtool here.
