Ctrl Extension compatibility problem

[blackout]

Hi,

I'm trying to develop a ctrl extension and I've included the rabbitmq-c, open ssl library and zlib compression library to the ctrl extension project.. (I've installed them as nuget packages from visual studio)
The code compiles with no errors but when I try to use the dll in WinCC OA, I get the fatal error message of:


5/ctrl, Location of the following log entry: , Line:1
WCCOAui (1), 2017.11.24 12:05:52.575, SYS, WARNING, 133, Could not load shared library D:\\Demo\\bin\\TestCtrlExt.dll, The specified module could not be found.

It might be from version

Hi Alper,

most of the times I see this message, it actually means that you miss some of the extension DLL dependencies in path. As dirty test, you could try to place the dependencies directly in WinCC OA installation bin directory and try to load your extension and see if it works or not.

I am having the same problem :"The Ctrl Extension is not compatible with the current library version 315000 of WinCC OA."
What is funny, that my colleagues use the same version and patch of WinccOA, they do register the subproject the same way as I, but my gedi refuses to start. We all use v3.15 p013

"Access is denied."
This is the information from the OS.
Any file access right problems ?

Thank you very much Martin,

moving the subproject over to drive C: (in Windows) did the trick. That means there must be something preventing WinccOA to access D: drive in my case.
