At any rate, I think the problem is more likely to be in automake than in autoconf, since this is a case of bad quoting in the Makefile, which is not under autoconf's control. In particular, I note that automake generates the following: cd $(top_builddir) $(SHELL) ./config.status $@ $(am__depfiles_maybe);; \ If, for some reason, $(top_builddir) didn't get defined correctly, then that would explain your symptoms. Automake could protect itself a bit better by using cd '$(top_builddir)' ... since cd will succeed but cd '' will fail, but that still doesn't explain the root cause for $(top_builddir) not expanding correctly. Or maybe the package you are compiling didn't use automake, and it is a bug in their hand-written Makefile.in? -- Eric Blake ebl...@redhat.com+1-801-349-2682 Libvirt virtualization library http://libvirt.org signature.asc Description: OpenPGP digital signature ___ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf

Scratch that - bash 4.1, zsh, and dash all share the same bug: $ bash -c 'cd '; echo $? 0 ksh93 is even worse - it changes to the home directory anyways. Of all the shells I tested, _only_ Solaris /bin/sh errored out! $ cd /tmp $ /bin/sh -c 'cd ; echo $?; pwd' /bin/sh: null directory $ echo $? 1 Looks like a gotcha to document in the autoconf manual. -- Eric Blake ebl...@redhat.com+1-801-349-2682 Libvirt virtualization library http://libvirt.org signature.asc Description: OpenPGP digital signature ___ Autoconf mailing list Autoconf@gnu.org http://lists.gnu.org/mailman/listinfo/autoconf

It seems the configure file is changing directories to home, which isn't
correct. Any ideas what's wrong? I'm guessing the srcdir variable isn't

Well, what exactly did you type to get the above ('make -e' by chance?)
and what is
grep ^top_srcdir Makefile
grep ^top_srcdir source_tree/Makefile.am
?
Which autoconf version (./config.status --version), automake version (head
Makefile), and make version do you use?
It could help to see the above happen with
make SHELL=/bin/sh -x
Cheers,
Ralf
