[Mono-list] Can cross Windows and Linux platform mono application include Windows .NET C# dll ?

[Maser, Dan]

   Yeah, I do this with mono and it works very well for me.   Meaning that I have managed C# code that uses an unmanaged DLL via p/invoke.  I compile the C# code with .NET on Windows and mono on linux, and I compile the unmanaged (c++) code with vc++ on Windows and gcc on linux; using the same C# code and C++ code.   But of course I had to plan ahead to do this... primarily by not using Win32 APIs directly in code, I use portable libraries like ACE, BOOST, STLPort, ICU, and occasionally have a #ifdef section for platform specific code.

Chris,

My understanding that the DLL will be an unmanaged one.  This is a great help for me.

Thanks,
Jerry

If the DLL is unmanaged (it sounds like it is) then including a
Windows build of it will do no good.  You will have to compile this as
a native Linux library for Mono on Linux to be able to use it.

If the library uses non-portable calls (such as win32 functions) then
you will have to do the standard C/C++ thing and #if your way to
portability, or find a portable function that does the same thing.
