I'm currently developing a c++ plugin for a windows simulator

dll needs to include a library of this simulator program which is

cygwin for the windows platform.
But now there is another problem. My .dll-project needs to use
external libraries which are only supported
in windows .lib format. So theres the issue that my VC Express
compiler can not use the .a library and the
cross compiler can not handle the .lib. I already read that even if
both, the .a and .lib, are static libraries there are
incompatibilities because of the used compiler.
I would prefer to disclaim the bypass of using cygwin and a cross
compiler at all. So is there any way of
converting the .a library in a native windows .lib?
The incompatibilities you refer to are the result of differences in
different
"vendors" C++ formats, not in the differences between library formats.
Actually a static .a and .lib have the same format. But the former
restriction overshadows the latter non-issue. You'll need to wrap your
library in C-callable interfaces if you really want to get this to work.
Perhaps the very recently update SWIG library will be helpful for you?

Off the top of my head, no. Well, other than manually creating C-callable
interfaces yourself. But I'll bet there's a project out there that would
help you do this if you poke around.
