yeah, I was there already and I assume kdevelop is even harder
because much bigger.

clever but lazy is to what until ld only add libs to NEEDED when
the ELF binary really uses symbols from it ;)

first 33%: There is at least one thing that can make life easier for all
KDE relibtoolization and later merges.  LIB_QT is currently:

LIB_QT = -lqt-mt  $(LIBZ) $(LIBPNG) -lXext $(LIB_X11) $(LIBSM) -lpthread

what's badly needed is a patch so is just LIB_QT=-lqt-mt.  This
would elimiate lots of s/LIB_QT/-lqt-mt/  that will never be accepted
upstream.

Same is of course true for other LIB defs that use several libs.
Digikam has e.g.

$ egrep 'LIB.*=.*(-l|\$).*(-l|\$)' Makefile
LIBPNG = -lpng -lz -lm
LIBSM = -lSM -lICE
LIBTOOL = $(SHELL) $(top_builddir)/libtool --silent
LIB_GPHOTO = -L/usr/lib -lgphoto2 -lm -L/usr/lib -lgphoto2_port
LIB_IMLIB2 = -L/usr/lib -lImlib2 -lfreetype -lz -lX11 -lXext -ldl -lm
LIB_QT = -lqt-mt  $(LIBZ) $(LIBPNG) -lXext $(LIB_X11) $(LIBSM) -lpthread
LIB_X11 = -lX11 $(LIBSOCKET)

All of them should be just -l<libname>.  Well LIBSOCKET)

I we have a patch to easly make them -l<libname> then the
Makefile.am changes are only additions or removal of $(LIB<whatver>)
and this should be perfectly fine for upstream to accept.

2nd 33 % is boring: ld will fail is a lib is missing.
In my experience this was easy enought to fix recursively
a tool is not that useful.

For the 3nd 33% finding the mininal set of required libs,
there was a lintian check posted on debian-devel that list
libs that are in NEEDED but no symbols are used from this lib.

I'm would gladly read about more tips and tricks to ease
the relibtoolization.  And I dance in circles when some
one provides the above mention patch for LIB vars! ;)

  To me vi is Zen.  To use vi is to practice zen. Every command is
  a koan. Profound to the user, unintelligible to the uninitiated.
  You discover truth everytime you use it.
