Hi @janne-hmp ,
I can't build GnollHackM (.NET MAUI 9.0 project), the error is as follows, can you update the repository to help us reproduce the error?

Thanks for your patience.

You need to follow these instructions:

https://github.com/hyvanmielenpelit/GnollHack/wiki/Build-Instructions-for-Android-Version-on-Windows-%28.NET-MAUI%29

The instructions require you also to build the Xamarin.Forms version of the game. You can copy the tileset images and sound banks from here:

• https://github.com/hyvanmielenpelit/GnollHackTileSet/releases
• https://github.com/hyvanmielenpelit/GnollHackSoundSet/releases

The instructions are for Android. @janne-hmp can provide instructions for Windows.

@janne-hmp : We should add the build instructions for the MAUI Windows version to the wiki.

Thanks for looking at this. The initial build instructions were a bit limited, since I wasn't sure if anybody checks this in fact out anytime soon. There are indeed a few files that GnollHackM requires for successful building that are not a part of the repository due to the large size or since they contain private information like passwords etc., as pointed out by Tommi. Also, the game relies on building the NetHack game data file (called nhdat) for the Windows MAUI version using GnollHack.sln solution, which is another necessary step. Let me do a more complete set of instructions to the wiki to enable building the Windows version, and I send you link soon. I didn't have a chance to do this earlier, since I started looking at the WinUI version last Thursday.

Here's the link to the more detailed version of the build instructions: https://github.com/hyvanmielenpelit/GnollHack/wiki/Build-Instructions-for-WinUI3-Version-on-Windows-(.NET-MAUI)

The whole Windows .NET MAUI version is very recent work-in-progress (started last week) so it was tough to say if the instructions are fully complete yet, but hopefully so. The build process is currently a bit intricately tied to both old NetHack / GnollHack Win32 Windows version (which generates Windows nhdat game data file) and old Xamarin.Forms version (originally just Android and iOS), where the rest of the code comes from, so it is not super-straightforward currently. The gnollhackwin project creates the GnollHack C library called gnollhackwin.dll to win\win32\xpl\GnollHackM\Platforms\Windows\libs. That said, I managed to make .NET MAUI version work for me (even getting debugging work for the C library), and the game works generally well for Android and iOS in both Xamarin and .NET MAUI.

In any case, let me know if you encounter any further problems, and I can fix the instructions, if need be.

Please attach a small reproduction sample to help debug this issue. A large app may have other, unrelated side effects and it is hard to debug any specific issue when there are many steps to get working. A smaller sample will help us get to it faster.

Also, please attach the full stack trace even if it does not make sense as there may be hints in there for the Windows teams.

Hi @janne-hmp. We have added the "s/needs-repro" label to this issue, which indicates that we require steps and sample code to reproduce the issue before we can take further action. Please try to create a minimal sample project/solution or code samples which reproduce the issue, ideally as a GitHub repo that we can clone. See more details about creating repros here: https://github.com/dotnet/maui/blob/main/.github/repro.md

This issue will be closed automatically in 7 days if we do not hear back from you by then - please feel free to re-open it if you come back to this issue after that time.

I actually figured out where this was coming from. It was caused by me accidently calling a non-exported function from a DLL, which the system did not find. The error message was just extremely weird, indicating something wrong with combase while in fact P/Invoke did not find the function from the DLL. Perhaps that can be made a bit clearer going forward. I added now the __declspec(dllexport) attribute to the function on the DLL side, and this work out now ok in that respect.
