[BUG] DllImport makes problems on some Pcs

[MrScautHD]

Issue description

Hello, I'm encountering an issue with the .dll importer in C#. It's a bit puzzling because it seems to work on some PCs but not others. On my main development machine, everything runs smoothly. However, on my test PC, I consistently encounter an error. Interestingly, on my sister's PC, it works flawlessly. It's quite perplexing, but I found that replacing the .dll with the original joltc one resolves the issue on any PC.

You have own joltc.dll? In that case I cannot help, if it happens with joltc.dll from this repo I can try to help.

Try also to install visual studio 2022 C++ runtime in case, you can open the joltc.dll in dependency walker and see what is missing.

I got some reports, here one that has a few more details:

Can you try with latest github version?

[MrScautHD]

Can you try with latest github version?

Sadly not, my project base on the nuget packet and if i try to compile it with the Source code (Github) i get some errors:

[amerkoleci]

Please try with version 2.2.2 from nuget

[MrScautHD]

Please try with version 2.2.2 from nuget

Same error

[MrScautHD]

looks like you're need to include libjoltc.dylib

[amerkoleci]

looks like you're need to include libjoltc.dylib

That's should be automatically be added by .net compiler

[MrScautHD]

it do not work then, only the C# library

[amerkoleci]

Don't know what to do, I don't have a macos, so it's impossible for me to debug and fix the issue

[MrScautHD]

Same on happans on linux, create a virtual machine for linux and try to debug it. (just on win does it work)

[MrScautHD]

ops sry nope it just happans on MacOS.

You dont need one, just get sure the .dll get added to the build.

[amerkoleci]

Lol, feel free to fix it and submit PR

[MrScautHD]

Lol, feel free to fix it and submit PR

Oh and it just happans for nuget if i build it with the github source code it works fine.

[MrScautHD]

Lol, feel free to fix it and submit PR

I got the bug!

the problem is you use '$(RuntimeIdentifier)'=='osx-universal'" instead of '$(RuntimeIdentifier)'=='osx-x64'"

With '$(RuntimeIdentifier)'=='osx-x64'" the .dll get generated.
