Hi,<br>
<p>
I configured sane-0.69 using `./configure --disable-static' on a<br>
Linux-2.0.3x machine.  Since I know shared libraries work on this<br>
platform, I usually do this in order to save on disk space and<br>
compilation time.<br>
<p>
Compilation went wrong in the lib subdirectory:<br>
[lots of files get compiled like this one:]<br>
gcc -c -DHAVE_CONFIG_H -I. -I. -I../include/sane -I../include -D_GNU_SOURCE -DPATH_SANE_CONFIG_DIR=/usr/local/etc/sane.d -DPATH_SANE_DATA_DIR=/usr/local/share -DV_MAJOR=0 -DV_MINOR=69 -I/usr/X11R6/include -O3 -fomit-frame-pointer -Wall -fPIC -DPIC usleep.c<br>
mv -f usleep.o usleep.lo<br>
ar r liblib.a alloca.o getopt.o getopt1.o sigprocmask.o strndup.o strdup.o strsep.o snprintf.o usleep.o<br>
ar: alloca.o: No such file or directory<br>
<p>
Obviously, the .o files have not been built by libtool.<br>
<p>
This is because of the Makefile.in in the lib subdir:<br>
----&gt;8----<br>
[...]<br>
LIBLIB_OBJS	= alloca.o getopt.o getopt1.o sigprocmask.o strndup.o \<br>
		  strdup.o strsep.o snprintf.o usleep.o<br>
LIBLIB_LTOBJS	= alloca.lo getopt.lo getopt1.lo sigprocmask.lo strndup.lo \<br>
		  strdup.lo strsep.lo snprintf.lo usleep.lo<br>
<p>
TARGETS = $(LIBLIB_OBJS)<br>
TARGETS = liblib.a<br>
<p>
.SUFFIXES:<br>
.SUFFIXES: .c .o<br>
.c.o:<br>
	@$(LIBTOOL) $(MCOMP) $(COMPILE) $&lt;<br>
<p>
all:	$(TARGETS)<br>
<p>
liblib.a: $(LIBLIB_OBJS)<br>
	ar r $@ $(LIBLIB_OBJS)<br>
	$(RANLIB) $@<br>
----8&lt;----<br>
So we only want the static library, and there is a special rule<br>
involving `ar'.  I don't get why there is mentioning of libtool in<br>
this Makefile fragment at all if all we want is a static library?<br>
<p>
I seem to recall there were some plans to have the build process use<br>
automake in the not too distant future.  If this is true, I think this<br>
will kind of automagically fix problems such as this one, and I'll be<br>
glad to just not use `--disable-static' until then.<br>
<p>
Greetings,<br>
	Alex<br>
