# Makefile for Netpbm
# Configuration should normally be done in the included file Makefile.config.
# Targets in this file:
#
# nonmerge: Build everything, in the source directory.
# merge: Build everything as merged executables, in the source dir
# package: Make a package of Netpbm files ready to install
#
# The default target is either "merge" or "nonmerge", as determined by
# the DEFAULT_TARGET variable set by Makefile.config.
# About the "merge" target: Normally the Makefiles build separate
# executables for each program. However, on some systems (especially
# those without shared libraries) this can mean a lot of space. In
# this case you might try building a "merge" instead. The idea here
# is to link all the programs together into one huge executable, along
# with a tiny dispatch program that runs one of the programs based on
# the command name with which it was invoked. You install the merged
# executable with a file system link for the name of each program it
# includes. This is much more important when you're statically
# linking than when you're using shared libraries. On a Sun3 under
# SunOS 3.5, where shared libraries are not available, the space for
# executables went from 2970K to 370K in an older Netpbm. On a
# GNU/Linux IA32 system with shared libraries in 2002, it went from
# 2949K to 1663K.
# To build a "merge" system, just set DEFAULT_TARGET to "merge" instead
# of "nomerge" in Makefile.config. In that case, you should probably also
# set NETPBMLIBTYPE to "unixstatic", since a shared library doesn't do you
# much good.
# The CURDIR variable presents a problem because it was introduced in
# GNU Make 3.77. We need the CURDIR variable in order for our 'make
# -C xxx -f xxx' commands to work. If we used the obvious alternative
# ".", that wouldn't work because it would refer to the directory
# named in -C, not the directory the make file you are reading is
# running in. The -f option is necessary in order to have separate
# source and object directories.

# program. This list is in a file called 'mergelist'. The make files
