native DLL cannot be loaded

Hello,

Ive searched the forums and tried some of the tips, like placing the DLL in a Plugins directory, or with x86 and x64 subdirectories for the different version or directly in the Assets-root. I have enabled the unsafe compile option in the player options and tried the "InitilializeOnLoad" for the static class, which loads the DLL.

But nothing helps.

If one would want to try out, it is the PCANBasic.dll for the Peak PCAN-USB adapter, included over the PCANBasic.cs (you actually dont need the driver installed to test if you can call any of the external routines).

Any ideas on that?

 

What's the platform and architecture it's been compiled for? Have you set the settings appropriately? What's the exact error message?

 

compiled for standalone on a x64 Win7 platform.

Its a simple "DLLNotFoundException", cant see any additional informations on that. But this already comes when playing in the editor.

 

It probably has a dependency on another DLL that also needs to be included. DLL error messages are frustratingly vague like that.

 

They provide an example VS project and I only need to copy that single DLL into the project-folder to make it work. Is there a way inside a working project to trace down the dependencies?

 

In that case, add it to the project folder (not into Assets, but on the same level). Entering playmode in the editor, the engine will usually check that location for assembly that cannot be found using other paths.

If the build does not work either, you have to make sure that the .dll has actually been copied over to the executables folder, too. If it isn't there, add it there as well.

 

thank you, that is working!
