  Downloaded the latest ltrace,
  using command : apt-get source ltrace

  ltrace version : 0.7.3 
  Before doing make , I am getting the error : cannot guess build type; you must specify one

  root at ubuntu:~/urvashi/ltrace-0.7.3# ./configure 
  checking build system type... config/autoconf/config.guess: unable to guess system type

  This script, last modified 2009-11-20, has failed to recognize
  the operating system you are using. It is advised that you
  download the most up to date version of the config scripts from

    http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD
  and
    http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD

  If the version you run (config/autoconf/config.guess) is already up to date, please
  send the following data and any information you think might be
  pertinent to <config-patches at gnu.org> in order to provide the needed
  information to handle your system.

  config.guess timestamp = 2009-11-20

  uname -m = ppc64le
  uname -r = 4.4.0-30-generic

  UNAME_VERSION = #49-Ubuntu SMP Fri Jul 1 10:00:36 UTC 2016
  configure: error: cannot guess build type; you must specify one

  Have u come across the same error before ?
  if not we need to fix this first.

  I have downloaded the latest ltrace from upstream,

  git://git.debian.org/git/collab-maint/ltrace.git

  Upstream ltrace is working fine.

  Hello Canonical,
                    Can you please have a look?
