# 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.  The make files do this recursively, via a link command that
#      combines multiple relocateable object files into one.  All we do here
#      at the top level is make merge.o and link it with netpbm.o and the
#      libraries.
#
#      This is the clean way, and we use it whenever we can.  But we don't
#      know how to do the link on every platform.
#
#   2) Each directory produces a list of all the object files in that 
#      directory and its descendants that need to go into the 'netpbm'
#      program.  This list is in a file called 'mergelist'.  The make files
#      do this recursively.  Here at the top level, we make mergelist and
#      then do one large link of everything listed in it, plus netpbm.o and
#      the libraries.
#
#      This doesn't require any special link command like (1), but is
#      not very clean.  The dependencies don't work right.  And at least
