NotSupportedException with web server inside arm64 container until wkhtmltopdf is installed explicitly about wkhtmltopdf-dotnet

[ilyahryapko]

Here's the libraries i've found in container

root@044be08df36e:/app# ldconfig -p | grep 'libwkhtml'
	libwkhtmltox.so.0 (libc6,AArch64) => /usr/local/lib/libwkhtmltox.so.0
	libwkhtmltox.so (libc6,AArch64) => /usr/local/lib/libwkhtmltox.so

@ilyahryapko I haven't added support for ARM64, we need the binaries and probably some additional code. I welcome PRs :)

[ilyahryapko]

@HakanL I will gladly commit that issue, but honestly speaking I do not have any idea on how to start.
My first thought was the following algorithm

1. add this libwkhtmltox I've found in my container to your runtimes repo
2. then somehow manage to edit Haukcode.WkHtmlToPdfDotNet.targets file in order to copy needed libraries via $(Platform) option
3. add new class WkHtmlModuleLinuxArm64 with corresponding public const string DLLNAME = "runtimes/linux-arm64/native/libwkhtmltox";
4. edit factory class and add check for process architecture using System.Runtime.InteropServices.RuntimeInformation.ProcessArchitecture and call new class mentioned before

Did I get everything correct or am I missing something?
Is there another way to get this 0.12.5 arm64 libwkhtmltox?

[HakanL]

That looks correct, I haven't done any development on ARM64, but give it a shot, create a fork and see if you can make it run locally first.

@ilyahryapko Can you see if the latest version fixed this?

[ilyahryapko]

@HakanL Sorry for a late reply. Unfortunately do not have M1 anymore so I am unable to test this

[HakanL]

Version 1.5.81 which is in NuGet now should support Linux ARM64. I have tested it in Docker on a Macbook Air M1, but more testing would be good.
