Load a .so from a Windows binary using Wine

[Raghavan Gurumurthy]

I have a Windows GUI application that runs on Wine (not Winelib). Now i want
to use that code to load a native Linux .so - how can i do this?

Thanks in advance,
Raghavan

Howso? I don't think wine has support for loading native shared libraries from windows apps. You'd have to write code to load the library (in the ELF format), map it into memory, etc.

HTH,

Write a proxy DLL that exports the functions in PE format, maps the 
arguments and calling convention, and calls the native so. Compile that 
as a winelib app.

Only winelib apps can technically call a native so, so calling your 
library directly from the PE is impossible without either employing a 
proxy, or implementing the linux loader yourself.

You could add a new Wine DLL which simply exports an interface to libdl
directly, assuming the calling conventions are compatible (you could
set the convention when compiling the native DSO). Then it would be
reasonably generic.
