a problem with libtool (searching for libiconv.la)

[Lorenzo Bettini]

Hi

while trying to configure and build a qt project under cygwin (see the 
thread "building a qt library") I'm struggling with this error reported 
by libtool while linking:

/bin/sh ../libtool --tag=CXX   --mode=link g++ -pipe -Wall -W -O2 
-DQT_NO_DEBUG  -g -O2 -Wl,--enable-runtime-pseudo-reloc   -o 
hello_qt.exe hello_qt-hello_qt.o -L/usr/lib/qt3//lib -L/usr/X11R6/lib 
-lqt -lXext -lX11
libtool: link: cannot find the library `/usr/lib/libiconv.la' or 
unhandled argument `/usr/lib/libiconv.la'

now, this libiconv.la (which, actually, is not installed in my system) 
is not named anywhere in the libtool generated by configure, and, most 
of all, if I manually run the link command on the command line (i.e., 
without passing through libtool), everything works fine (besides some 
warnings)!

g++ -pipe -Wall -W -O2  -DQT_NO_DEBUG  -g -O2 
-Wl,--enable-runtime-pseudo-reloc   -o hello_qt.exe hello_qt-hello_qt.o 
-L/usr/lib/qt3//lib -L/usr/X11R6/lib -lqt -lXext -lX11
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: 
warning: auto-importing has been activated without --enable-auto-import 
specified on the command line.
This should work unless it involves constant data structures referencing 
symbols from auto-imported DLLs.Info: resolving QString::shared_null 
   by linking to __imp___ZN7QString11shared_nullE (auto-import)

what is going wrong?

thanks in advance
        Lorenzo
