The problem: The new version of coreutils, adds use of canonicalize_file_name() function defined in canonicalize.h The problem I encountered is at compile time, the function is redefined to rpl_canonicalize_file_name by means of a macro, and I get an undefined reference error. //-- stdlib.in.h #if @GNULIB_CANONICALIZE_FILE_NAME@ # if @REPLACE_CANONICALIZE_FILE_NAME@ # if !(defined __cplusplus && defined GNULIB_NAMESPACE) # define canonicalize_file_name rpl_canonicalize_file_name # endif I've looked for REPLACE_CANONICALIZE_FILE_NAME and found out that is being set in configure, which is generated from canonicalize.m4 # canonicalize.m4 serial 24 dnl Copyright (C) 2003-2007, 2009-2012 Free Software Foundation, Inc. dnl This file is free software; the Free Software Foundation dnl gives unlimited permission to copy and/or distribute it, dnl with or without modifications, as long as this notice is preserved. # Provides canonicalize_file_name and canonicalize_filename_mode, but does # not provide or fix realpath.

In fact, I could not make a logic for "guessing yes" and "quessing no" because to me it looks like they are not verified against and thus I'm missing the reason of their usage. However, I'm assuming I missed something because they are used quite heavily. I don't have experience with autoconf so I may have missed the "right way" to fix this.
