[sword-devel] Sword Windows library problem

[Daniel Hughes]

Your the first person to try the bindings on windows.

It could be the calling convention.

The bindings are written to use Cdecl calling convention.

It may be that Visual studio has built sword using the stdcall calling
convention.

I will need someone who knows more about c/c++ and the calling
conventions to comment on this.

You can try changing the calling convention in the bindings by editing
them in the NativeMethods.cs class to confirm this.

However if it turns out that sword does use a different calling
convention on windows to linux then that could be a problem. It may be
that you need to tell Visual Studio to build sword using Cdecl calling
convention.
