OpenDDSWrapper (or depenency) not found.

[jrobideaux]

Hello everyone,

I've been following along w/ the instructions posted here: Getting Started
I've managed to get the IDL and Publisher projects to build with no errors.
However, when I run the Publisher app, I get the following error message.
Looks to be happening right at the call to Ace.Init().

C:\Projects\Publisher\bin\Debug\net6.0\win-x64>Publisher.exe Unhandled exception. System.DllNotFoundException: Unable to load DLL 'OpenDDSWrapper' or one of its dependencies: The specified module could not be found. (0x8007007E) at OpenDDSharp.Ace.UnsafeNativeMethods.NativeInit() at OpenDDSharp.Ace.Init() at Publisher.Program.Main(String[] args) in C:\Projects\Publisher\Program.cs:line 13

I have tried with the latest nuget packages (0.8.22297.100), as well as the one cited in the above article (0.8.22127.96)

Any insights or questions would be most appreciated!
Many thanks in advance.
-John

Have you installed the C++ Redistributable in your system?

[jrobideaux]

I do have the "C++ 2022 Redistributable Update" installed. But I see there's an "MSMs" as well.
I can try adding that one and see what happens.

Guess I should mention that I am using VS 2022. Do I need to try this with VS 2019, perhaps?

[jmmorato]

VS 2022 should be ok

[jmmorato]

Try to build using directly the dotnet CLI:
dotnet clean Publisher.csproj
dotnet build Publisher.csproj --runtime win-x64 --no-self-contained

[jrobideaux]

Yup.. I've done the following from the command line, as well as opening up the VS Command Prompt window and trying it there.

C:\Projects>cd Publisher
C:\Projects\Publisher>dotnet clean Publisher.csproj

Please execute dumpbin /dependents OpenDDSharpWrapper.dll and paste the output here, perhaps we find some clues

I have published a new version 0.8.22309.101-beta that includes TAO_Valuetype.dll file.
Please, check it and let me know if works for you.

Fixed on version 0.8.23023.106
