For me, that's:

$ autoconf --version
autoconf (GNU Autoconf) 2.57
$ automake --version
automake (GNU automake) 1.6.3
$ libtool --version
ltmain.sh (GNU libtool) 1.5.0a (1.1220.2.27 2003/08/29 14:21:22)
$ libtoolize --version
libtoolize (GNU libtool) 1.5.0a

I also had to remove @DRIVERS@ from liblcd4linux_la_SOURCES, automake
complained:

   Makefile.am:75: `liblcd4linux_la_SOURCES' includes configure
   substitution `@DRIVERS@', and is referred to from
   `liblcd4linux_la_SOURCES': configure substitutions not allowed in
   _SOURCES variables

Plus I had to remove a lot of objects from the lcd4linux_SOURCES
target since automake complained:

   automake: Makefile.am: object `debug.$(OBJEXT)' created both with
   libtool and without

(Also for cfg, lock, udelay, display, pixmap, bar, icon, fontmap, and
parport.)

Configure seems to work:

   $ ./configure --prefix=/tmp/schemitz/trash --with-drivers=X11
   [...]
   configure: creating ./config.status
   config.status: creating Makefile
   config.status: creating config.h
   config.status: executing depfiles commands
   $

But make fails with a curious problem. Each object seems to compile:

   source='display.c' object='display.lo' libtool=yes \
   depfile='.deps/display.Plo' tmpdepfile='.deps/display.TPlo' \
   depmode=none /bin/sh ./depcomp \
   /bin/sh ./libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I.
   -I/usr/X11R6/include -D_GNU_SOURCE -Wall -g -O2 -c -o display.lo `test
   -f 'display.c' || echo './'`display.c

(and the same for all the other objects), but the linker complains:

   (cd . && ln -s display.lo display.o)
[ plus the same for all the shared objects ]
   gcc -shared  display.lo debug.lo cfg.lo lock.lo pixmap.lo bar.lo icon.lo
   fontmap.lo parport.lo udelay.lo  -lm  -Wl,-soname -Wl,liblcd4linux.0 -o
   .libs/liblcd4linux.0.9.11
   gcc: display.lo: No such file or directory
   gcc: debug.lo: No such file or directory
   gcc: cfg.lo: No such file or directory
   gcc: lock.lo: No such file or directory
   gcc: pixmap.lo: No such file or directory
   gcc: bar.lo: No such file or directory
   gcc: icon.lo: No such file or directory
   gcc: fontmap.lo: No such file or directory
   gcc: parport.lo: No such file or directory
   gcc: udelay.lo: No such file or directory

And the linker is right! The object files do not exist. Apparently,
libtool didn't really invoke the compiler at all! Proof: mv away
the gcc executable and run "make" again: no error on compile, no
warning.

More trouble: on the second invokation, "make" complains (again,
correctly) about already existing symlinks:

   (cd . && ln -s display.lo display.o)
   ln: `display.o': File exists

Hope this helps. I surely do need help here.

Ciao, patrick
