Re

So you say Larry that i need an import library
(foo.lib) to link against in msvc++.
I think so also.

My problem is now to create this .lib.
Indeed, in the bottom of the link
http://cygwin.com/cygwin-ug-net/dll.html, it's
explained to create a .def file and .a file, but not a
.lib file that i need in msvc++

In fact i don't need a Cygwin-compatible import
library but a MSVC++ -compatible import library,
because i want to compile my prog with msvc++

(if you ask me why, the simple program is in fact a qt
program, and trolltech proposes only compilation with
borland C++ and msvc++ which both use .lib import
library)

maybe there's some docs in the mailing liste archive,
but i have great great difficulties with the search
engine http://cygwin.com/ml/cygwin/

i search for dll + link and i get weird results, maybe
you have some link or good keywords to reach important
results ?

Thanks
enzo
