Hi guys, I'm trying to port an application onto Windows that was originally developed for UNIX using rpc, pthreads, and AF_UNIX sockets. I have used cygwin to compile this application successfully. One of the components built is a DLL which I want to invoke from a C Sharp application. However, the application crashes whenever I call this DLL via pinvoke in C Sharp.
************** Exception Text ************** System.DllNotFoundException: Unable to load DLL 'perm.dll': Invalid access to memory location. (Exception from HRESULT: 0x800703E6) at WinPcapRedirectorUI.Perm.meme () at WinPcapRedirectorUI.MainForm.statisticsButton_Click(Object sender, EventArgs e) in C:\eclipse\workspace\winperm\WinPcapRedirectorUI\MainForm.cs:line 74 at System.Windows.Forms.Control.OnClick (EventArgs e) at System.Windows.Forms.Button.OnClick(EventArgs e) at System.Windows.Forms.Button.OnMouseUp(MouseEventArgs mevent) at System.Windows.Forms.Control.WmMouseUp(Message& m, MouseButtons button, Int32 clicks) I verified that the cygwin*.dll are in the path. I made a strip down version of a dll, it exhibited the same behavior. Next, I compiled the library with -mno-cygwin flag which surprisingly worked. I suspect that cygwin1.dll does not work with pinvoke. Can anybody confirm this is true? I prefer not to have to port the native application to Visual C or mingw32 as there are a lot of rpc and AF_UNIX sockets. Are there any other alternatives? Thanks in advance for your help!
