Can my plugin load a c dll with dllimport?

[Xty]

I have a C dll that I'm trying to load with my plugin but in the debug console it says DllNotFoundException when it tries to load the dll.

I got the dll working with a C# console application so I'm fairly certain it works.

I put the dll in the same directory as the plugin (I'm using the old plugins directory) and I know the plugin is loading.

Is it possible to load a C dll with a plugin, and if yes, can anyone tell me where it should go or what I'm doing wrong?

I'm not convinced that it is, given that unity runs Mono, not .net (though they are both c#). Try looking into the mechanism Mono uses to load them.

I think someone managed to load a c dll in an earlier version of KSP. You could try moving the dll into the root directory of KSP (where KSP.exe is located). For standard .NET/Mono applications that is the location that is searched when trying to use an external dll.

You should be able to find out where Mono is actually looking for your native dll via Process Monitor, just in case the places already suggested do not work.

It is possible to talk to a C DLL from a C# DLL. The modder who did KerbComAvionics did just that (there's a C DLL "lpsolve.dll" included in the package). You can look at the source for that mod to see what you have to do in the C# DLL to load it.

You would have to cross compile the C DLL to support multiple platforms (mac / Linux / windows).

Putting it in the main directory fixed it. I took a look at KerbComAvionics but the source doesn't seem to be updated, I'm guessing if I put my mod in the GameData folder then it might be loadable from there, either that or a relative path.

Thanks everyone.
