I'm writing a program in which I have a Windows DLL that I need to load.
The DLL contains a function that
returns a pointer to some data, and I want to expose that data as file
data in a Fuse file system.
My first thought was that I could have the program load the DLL using
winelib, but I'm not sure what's
involved in this and whether the resulting program could also use the Fuse
libraries. I'm a bit of a
novice to Wine, and Linux programming in general, so I'd appreciate any
expert opinions you guys have about
the best way to do this.
Unfortunately you can't just link to winelib with -lwine or something, because the Wine DLLs(and most likely the Windows DLL) need some extra services running to work properly. That includes things like a certain memory layout, the registry, etc.
You have to use winegcc(see 'winemaker' for starting points). That way your app is compiled to a .exe.so file that can be run with 'wine foo.exe.so' or with a helper script. This application is a native Linux app, and it can link to Linux libraries like Fuse, and at the same time use Win32 API calls from Wine and e.g. open a DLL with LoadLibrary.
