[Nix-dev] Chrooted build failure with trunk

[Ludovic Courtès]

Hello,

I fail to build a few packages in a chroot with the current trunk.
Examples include Gnash and GnuTLS:

  libtool --mode=link gcc -Wl,--version-script,../exports  -rpath /nix/store/rk7n8vgdylgaqpix5pg8g8m3nddr2wqg-acl-2.2.47/lib -version-info 2:0:1 -o libacl.la acl_add_perm.lo acl_calc_mask.lo acl_clear_perms.lo acl_copy_entry.lo acl_copy_ext.lo acl_copy_int.lo acl_create_entry.lo acl_delete_def_file.lo acl_delete_entry.lo acl_delete_perm.lo acl_dup.lo acl_free.lo acl_from_text.lo acl_get_entry.lo acl_get_fd.lo acl_get_file.lo acl_get_perm.lo acl_get_permset.lo acl_get_qualifier.lo acl_get_tag_type.lo acl_init.lo acl_set_fd.lo acl_set_file.lo acl_set_permset.lo acl_set_qualifier.lo acl_set_tag_type.lo acl_to_text.lo acl_valid.lo acl_size.lo acl_to_any_text.lo acl_entries.lo acl_check.lo acl_error.lo acl_cmp.lo acl_extended_fd.lo acl_extended_file.lo acl_equiv_mode.lo acl_from_mode.lo __acl_to_any_text.lo __acl_to_xattr.lo __acl_from_xattr.lo __acl_reorder_obj_p.lo __libobj.lo __apply_mask_to_mode.lo perm_copy_fd.lo perm_copy_file.lo -lattr ../libmisc/libmisc.la
  shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such device or address
  pwd: error retrieving current directory: getcwd: cannot access parent directories: Success
  pwd: error retrieving current directory: getcwd: cannot access parent directories: Bad address
  chdir: error retrieving current directory: getcwd: cannot access parent directories: Success

In both cases, it happens when Libtool is invoked in link mode.  The
"shell-init" error message comes from Bash.

Looking at Bash' builtin/common.c:get_working_directory, I couldn't find
a clue as to what's failing.  Furthermore, `ENXIO' is not documented as
a valid return value for `getcwd(3)'.

Is anyone else experiencing this?  Any hint?

Thanks,
Ludovic.
