How to produce shared inter-library with static library?

[yuan zheng]

Hello, everyone:
       I want to produce a shared inter-library on mingw32 on winxp. But it prompted
that "can not link to static lib archive" and then generated a static lib. I have use 
the options "-no-undefined -shared".

my link line:
------------------------------------------------------------------------------------------------------------------------------
/bin/sh ../libtool --tag=CC   --mode=link gcc  -g -O2 -mms-bitfields -no-undefi
ed -shared   -o libcommon.la -rpath /opt/skyeye/lib/skyeye skyeye_module.lo sup
ort.lo breakpoint.lo thread_ctrl.lo sim_ctrl.lo step.lo mman.lo usleep.lo getti
eofday.lo skyeye_pref.lo skyeye_arch.lo skyeye_options.lo skyeye_config.lo misc
options.lo skyeye_log.lo skyeye_command.lo skyeye_cli.lo default_command.lo sky
ye_mm.lo skyeye_mach.lo skyeye_device.lo pen_buffer.lo skyeye_uart_ops.lo bank_
ps.lo io.lo ram.lo flash.lo skyeye_bus.lo bus_recoder.lo loader_elf.lo loader_f
le.lo callback.lo -L../third-party/bfd/.libs/ -lbfd -L../third-party/libiberty/
ic -liberty -lreadline ../libltdl/libltdlc.la    -lpthread -lm -liberty -lc  -l
svcrt -lws2_32 -lwinmm -ladvapi32
------------------------------------------------------------------------------------------------------------------------------

the print info:
------------------------------------------------------------------------------------------------------------------------------
*** Warning: This system can not link to static lib archive C:/MinGW/lib/libbfd
la.
*** I have the capability to make that library automatically link in when
*** you link to this library.  But I can only do this if you have a
*** shared version of the library, which you do not appear to have.

And then it generated "libcommon.a", rather than "libcommon.dll" which I want.

How can I do to get what I want?
