Compile issues (Xamarin.Forms)

brianphilips · January 21, 2022, 11:06pm

I opened a private ticket but I am hoping someone else can help me here.
Im using GD.Viewer 22.1.1 with VS2019 and Xamarin.Forms. When I go to compile the project screams about a bunch of other Aspose assemblies missing references. Has anyone encountered this? If so, how the hell do you fix it? Ive been stuck on this for over a week.

I’m sorry for the delayed response. Please check the provided solution at Document Viewer .NET API on Mac OS - #5 by atir.tahir. In general, you have to add packages for all the Aspose libraries. I’m reattaching the files listed in that topic:

TestViewer.zip (349.0 KB)
packages.png (416.4 KB)
codesets.jpg (283.0 KB)

Please let us know if it works for you.

Thank you I will take a look see at this in the coming days. I am really hoping to get past this hurdle. My only other option is to offload the viewer library in the cloud and I am really trying to avoid that.

so I looked at the project and did the same as suggested in the attachments. I am now getting the following error:

It’s possible that the package versions should match.

brianphilips · January 24, 2022, 9:31pm

Still getting this error after changing the versions. It appears to be an issue with linking.

@brianphilips

Might you share your csproj file?

brianphilips · January 25, 2022, 2:00pm

Sure no issue. I need to figure out how to attach them.

I successfully compiled and linked your projects with Visual Studio 2019. You tried to build in the Visual Studio 2022 Community right?

Might you try to build with Visual Studio 2019?
I try to reproduce your issue with Visual Studio 2022 Community.

@brianphilips
I can’t reproduce your issue with your csproj files, might you attach the complete project here?

brianphilips · January 27, 2022, 3:26pm

I tried 19 and 22 and 17 for that matter. None of them would compile the Xamarin.Forms application against a mac. The issue was with mtouch linking the binaries. I have a windows forms project that compiles just fine.

brianphilips · January 27, 2022, 3:43pm

Also when compiling are you doing this directly on a MAC or are you doing this on Windows connected to a mac? Im happy to setup a teams meeting if you would like to see what I see.

mikhail.evgrafov.aspose · January 27, 2022, 4:35pm

@brianphilips

I compiling in Windows Visual Studio, without MAC. As I understand you - the issue is present when you try to compile and deploy to MAC right?

vladimir.litvinchik · January 30, 2022, 4:37pm

@brianphilips

Unfortunately, it seems that there is no simple solution to this issue. We’ve tried to build a sample app that references GroupDocs.Viewer on MAC using Visual Studio for MAC but the build fails with the following error:

MTOUCH : error MT2001: Could not link assemblies. Reason: Value does not fall within the expected range.

While this solution has pros and cons it should definitely work.
