# 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.
#                                                           -- jwz, 30-Jun-98
