ql-win / quicklook.plugin.helloworld Goto Github PK

Hi,

Thanks for this great piece of software, I'm devlopping a viewer plugin for a particular astroimage format called FITS. Here is the project link.

The core of my plugin is in C++ which is built as a DLL. The plugin.cs calls functions in it like

 [DllImport(@"viewer_core.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Unicode)]
        public static extern IntPtr FitsImageCreate(IntPtr path);

However at runtime, my plugin crashes and the exception log in QuickLook indicates bad image format.

As far as my little knowledge in the Windows world and some Googling goes, this means the plugin.dll is loading my viewer_core.dll which targets the wrong architecture. Here is some information that I gathered in this regard.

1. My machine is running 64bit windows. The plugin.cs project is using build configuration "AnyCPU", and my C++ project is built as x64. This produces the above exception.

2. Same machine. The plugin.cs project is using build configuration "x86", and my C++ project is built as win32. This causes QuickLook to crash at startup.

3. I have a standalone viewer in c# just for testing purpose, it shares the same code as plugin.cs. This viewer runs ok as x86 with a win32 C++ dll.

It seems to me that neither x64 nor win32 build works. So please advice on how to build a correct C++ DLL.

Thanks

Should QuickLook.Plugin.Metadata.config be included since this is required for a plugin to install?
