# utils/Makefile.in --- xscreensaver, Copyright (c) 1997-2010 Jamie Zawinski.
# the `../configure' script generates `utils/Makefile' from this file.
# The utilities in this directory are used mostly by the demos in ../hacks/.
# The Makefile in that directory builds executables by simply referencing
# the .o files in this directory.

#
# Some rambling about dynamic libraries follows, ignore it if you don't care
# (which is almost assuredly the case.)
#
#
# It would probably be sensible to just build a single .a file in this
# directory, and link the hacks against that (statically.) I haven't done
# that for two reasons: first, it works now, and why fix what ain't broke;
# second, it wouldn't actually improve anything for the end user (it would
# just make the Makefiles be a little smaller.)
#
# People sometimes suggest that the stuff in this directory should be in a
# dynamic library, and that the hacks should be linked dynamically against
# it. I haven't done this for a number of reasons:
#
# * First, the only thing that would improve would be disk space, in that
# the executable files themselves would be smaller. That's it. Many other
# things would get worse if we used a dynamic library:
#
# * Complication of installation procedures: suddenly, before any of the
# hacks will work, you need to have a dynamic library installed, and
# the system configured to use it. This is, basically, rocket science.
# Most people don't know how to do this, it's a huge pain, and on many
# systems, it requires root access.
#
# * Complication of the Makefile: every system builds dynamic libraries
# differently. Every compiler takes different flags. I don't want to
# do the hand-holding for the scores of Unix systems and compilers on
# which people try to build this program.
#
# * Reduction of maintainability: gdb is remarkably bad at dealing with
# debug info in dynamic libraries, and when debugging a hack, one would
# constantly be fighting the linker and the debugger (or linking
# statically when debugging.)
#
# * Version skew: when things are statically linked, it's perfectly ok to
# make incompatible changes to the APIs defined in this directory, so long
# as the current version in ../hacks/ is in sync. Much more care would
# need to be taken with such things if dynamic libraries were involved,
# to make sure that the major and minor versions of the library changed
# at the appropriate time. This isn't too hard, but it's more work, and
# yet another opportunity to screw up.
#
# * Runtime memory usage goes *up*. That's right, up! When a program
# links in a dynamic library, the whole library is brought into the
# address space, not just the files that are actually used. Normally,
# this is ok, because if several programs are using (for example)
# libX11.so, chances are that the savings outweighs the overhead. But
# the nature of xscreensaver is that only one of the hacks ever runs at
# a time -- so there would never be a second program using the utils/
# dynamic library with which things could be shared.
#
# * Runtime speed decreases slightly, since dynamic code is marginally
# slower. On modern machines, this probably doesn't make a perceptible
# difference, however.
#
# So basically, I just don't think using libraries would be a win, and it would
# definitely cause more of a maintenance and portability headache. However,
# if someone else wants to do the work to make it be an option to configure,
# and verifies that it works on several (more than three) different Unixes,
# I'd be happy to take the patches.
