EWO and shared library

[dojdev]

My EWO uses the shared library. When the widget is started, the following message is displayed in the log:

Code: Select all

How can I fix this?

I use WinCC OA v3.14, 9 patch.

"My EWO uses the shared library."

Which one ?

If you use an additional shared library not provided by wincc_oa, which resides in a location which is not in the PATH, then the operating system is not able to find it and therefore not all needed functions
will be found.
Simply try to put all external shared libraries (dlls) into the wincc_oa-install/bin directory should solve the problem.
