Makefile

   1 # The PostgreSQL make files exploit features of GNU make that other
   2 # makes do not have. Because it is a common mistake for users to try
   3 # to build Postgres with a different make, we have this make file
   4 # that, as a service, will look for a GNU make and invoke it, or show
   5 # an error message if none could be found.
   6
   7 # If the user were using GNU make now, this file would not get used
   8 # because GNU make uses a make file named "GNUmakefile" in preference
   9 # to "Makefile" if it exists. PostgreSQL is shipped with a
  10 # "GNUmakefile". If the user hasn't run the configure script yet, the
  11 # GNUmakefile won't exist yet, so we catch that case as well.

  14 # AIX make defaults to building *every* target of the first rule.  Start with
  15 # a single-target, empty rule to make the other targets non-default.
