OPC UA in WINDOWS 10
lazarus / 38-Networking and Web Programming

----------------------------------------------------------------------

Hello
Good,
I am testing the example in lazarus to connect to an OPC UA server
using the libopen62541.dll library.

The source code is an example that I have found on the net, that other
forums have answered working on linux.

Here in windows I can't find the problem because it is not working for
me.

I have placed the library in the executable folder, I have placed a
path in another folder where the library is.

But I always get the error.

Who can help me?

Without any knowledge from me about libopen62541.dll I can tell that
this problem usually occurs when the bitness of the compiler and the
library do not match (32-bit vs 64-bit) or that the library depends on
the presence of other libraries (and those other libraries are
currently missing).
