Wow, I'm sorry about that, I actually hadn't tested the plugin on Windows. Too many operating systems to take care of 😅 But I do have a Windows machine here, so I'll take a look and fix this, shouldn't be too complex (probably just compiled it with a wrong flag or something like that).

[gilzoide]

Hey @sdkl, I fixed Windows support, please try the 1.0.0-preview6 version and tell me if it works or not. Weird that the MinGW build I had made in Linux for 1.0.0-preview3 worked here, but the last one I made on macOS for 1.0.0-preview5 did not 🤷‍ Either way, since I was already in Windows, I just rebuilt the DLL with G++ in Windows and now it works, hurray!

[sdkl]

@gilzoide I try in my Windows, but the problem seems still exist. And i build win dll via cmake and vs work well. When i check the dll dependents, i found difference

[gilzoide]

Oooh, ok, that makes sense. Sorry about that, I forgot about that kind of problem with dependency DLLs. Thank you very much for finding the culprit, it should be easy enough to fix this.

[gilzoide]

So, @sdkl I was able to generate a DLL that depends solely on KERNEL32.dll and msvcrt.dll, both of which should be present by default in any Windows system. My MSVC setup is not working well, so I just linked libgcc and libstdc++ statically using MinGW. The library is now 1.4MB instead of ~200KB, but this shouldn't be much of a problem.

If you could please test the version in branch bugfix/windows-dll-dependencies and tell me if it works now, both in editor and player builds, I'd appreciate the feedback ^^

[sdkl]

@gilzoide ok,test in my windows unity editor and player build work well

[gilzoide]

All right, thank you so much for reporting the problem and testing the fix!

Seems like this issue resurfaced in 1.0.3, downgrading to 1.0.2 fixed it.

[gilzoide]

Oh my, that's weird. Thanks for the report again! In these cases, you can reopen the issue =]

[gilzoide]

Hey @dandevs, can you please check if branch dockerfile-builders works in your Windows? I've added Dockerfiles for building the libraries and updated all builds using them. Both 1.0.2, 1.0.3 and this new branch work on my Windows machine, but I don't trust it for this kinds of problems. If you confirm it works, I'll merge it, consider this issue as fixed and release the new fixed version as 1.0.4.

[dandevs]

@gilzoide It works! Thanks =]

[gilzoide]

Nice! I'll always build for Windows using the Dockerfile to avoid future problems. Version 1.0.4 is released, should be available in OpenUPM soon. Cheers \o/
