Shared library question

[Josep Lluis Colom]

I used autoconf/automake/libtool to write a package that builds two
shared libraries in Linux, and it worked as expected.
Now I'm trying to do the port to Windows.

After installing Cygwin software. I can't build the shared libraries.
After compiling the source modules, libtool complains with: "Warning:
undefined symbols not allowed in i686-pc-cygwin shared libraries". Only
'.a', '.la' and '.lai' files are built.

Someone knows what its the pitfall?

(I'm using the same source files I used in Linux platform. Is that ok?
Shall I define some kind of dllexport like in plain Windows DLLs?
There's some clear sample hot to do it?)

Thanks.
