Building Cantact.dll

[Elliot Woods]

I'm trying to build a Cantact.dll in x64
(Actually I need to wrap it in .NET for an x64 .NET project)

I can find an x86 version of cantact.dll in the cantact branch of your busmaster fork
Also I can see in this repo there is the driver/src/c/mod.rs which seems to be the source code for cantact.dll

However, I'm not sure how to build this to x64
When I try to build the repo with cargo i get the following errors:

For more information about this error, try `rustc --explain E0308`.
error: failed to compile `cantact v0.0.7 (C:\dev\cantact)`, intermediate artifacts can be found at `C:\dev\cantact\target`

Caused by:
  could not compile `cantact`.

To learn more, run the command again with --verbose.

I will keep trying here

i managed to get this to work (by just building the library and not the app)
