1# The Postgres make files exploit features of GNU make that other makes 2# do not have. Because it is a common mistake for users to try to build 3# Postgres with a different make, we have this make file that does nothing 4# but tell the user to use GNU make. 5 6# If the user were using GNU make now, this file would not get used because 7# GNU make uses a make file named "GNUmakefile" in preference to "Makefile" 8# if it exists. Postgres is shipped with a "GNUmakefile". 9 10 11# AIX make defaults to building *every* target of the first rule. Start with 12# a single-target, empty rule to make the other targets non-default. 13all: 14 15all install clean check installcheck: 16 @echo "You must use GNU make to use Postgres.
