SfPdfViewer component erreur Syncfusion.EJ2.PdfViewer.PdfiumNative' threw an exception on load pdf on web assembly

Hello,

I'm considering your UI kit to be used in my project, but I'have a problem with the SfPdfViewer 

The component SfPdfViewer works great on windows but on the mac environnement with visual studio for mac I have this erreur on load pdf Syncfusion.EJ2.PdfViewer.PdfiumNative' threw an exception.

When I start my application on the document viewer tab, the pdf not load and in the code I saw Syncfusion.EJ2.PdfViewer.PdfiumNative' threw an exception on pdfviewer.Load(stream, jsonObject) result.
I saw an other thread on this subject but nothing seems to work : https://www.syncfusion.com/forums/151628/the-type-initializer-for-syncfusion-ej2-pdfviewer-pdfiumnative-threw-an-exception

I send you in attachement a sample project to reproduce

Hi Nicolas,  
  
Based on the provided details, we suspect that you are using Syncfusion.Blazor.PdfViewerServer.Windows NuGet package in the mac platform, so that the issue occurs. Kindly use the Syncfusion.Blazor.PdfViewerServer.OSX NuGet package to work with mac environment. We have shared the UG documentation for your reference.  
  
  
Kindly try it and revert to us, if you have any concerns about this.

Hi Dhivya,

Thanks you for the direct link I don't know why my nuget manager don't suggested me this package

And I have an another question I want to host the serveur on linux docker, so if I follow the logic I must change the dll for this one :
Syncfusion.EJ2.PdfViewer.AspNet.Core.Linux

It's compatible for all distribution ? CentOs, Debian ?

Thanks
Nicolas

Hi Nicolas,

Dhivya.

Hi Nicolas, 


Sorry for the inconvenience . We are facing the below script error while checking in DebianOs and CentOs. Still, we are analyzing this with high priority. We need some time to analyse and resolve these issues and  update the further details on 17 March 2021

Hi Nicolas, 
 
 
Thank you for your patience. 
 
 
We have checked the attached sample in DebianOs and CentOs. In our PDF Viewer we are using pdfium libraries to render the PDF documents. We suspect that the pdfium dependencies are missed in the sample which you have shared. Kindly use the below commands to install the dependencies in your machine. 
 
We have installed the following dependencies via root terminal: 
 
For CentOs: 
              
 
yum install -y   glibc-devel  
yum install -y wget
wget http://mirror.centos.org/centos/7/os/x86_64/Packages/libX11-devel-1.6.7-2.el7.x86_64.rpm yum install libX11-devel 
//Navigate to web-service project and use the below command   
export LD_LIBRARY_PATH=/lib64/ 
 and then executed dotnet run. 
 
 
 
 
For DebianOs; 
 
 apt-get update && apt-get install -y --allow-unauthenticated libgdiplus libc6-dev libx11-dev 
  //Navigate to web-service project and use the below command 
  dotnet run. 
 
 
 
Kindly try it and revert us, if you have any concerns about this. 
 
 
Regards, 
Dhivya.
