Issues running on Raspberry pi 5

[Nichlas-Schmidt]

hello,

I have scoured the internet, but I keep getting errors when trying to run on my raspberry pi.

What I have tried:
Using Q8-AnyCpu (did not work, got error that some x86.so file not being found|
PropertyGroup>
true
in my csproj
Q8-arm64, I have both the dll and the .so file present but I still get error.

the .so file is also present in runtimes

It's possible that this library requires a dependency that you are missing? What is the output of ldd Magick.Native-Q8-arm64.dll.so?

[Nichlas-Schmidt]

Hello and thanks for the quick response :o

I think the closest ive gotten is to use AnyCPU, with AnyCPU I get this error (why is it looking for x86 when my compile only includes arm64) With AnyCPU, it doesnt fail on the using statement, but when I try to do actual code with ImageMagick

Not sure, I am a bit clueless when it comes to linux to be honest, I just use it as my server

AnyCPU error during runtime

this is the output of the command you suggested

[dlemstra]

Odd that this command doesn't work for you. And thanks for providing more information. I would advise you to switch to switch to the Magick.NET-Q8-arm64 package. For some odd reason it's trying to load the 32 bit version of the library instead of the arm64 one.

p.s. A tip for the next time you report an issue on GitHub: Please don't take screenshots but copy paste the text into the issue inside a ``` block.

heyo,

I tried the mention package. With that package I get the error in the first post (Could not load Magick.NET-Q8-arm64) with file not found. That was the initial issue, .so file etc is there in both runtimes folders and in the main folder and .dll is present but it still says it cannot find it, not sure how to fix

I do screenshot because my server is not letting me copy paste sorry :D

[dlemstra]

It really feel like this has to do with the machine you are running this on. I just did a quick change to my builds to check the output of the ldd command and I am getting this:

libresolv.so.2 => /lib/aarch64-linux-gnu/libresolv.so.2 (0x00000055051c3000)
libpthread.so.0 => /lib/aarch64-linux-gnu/libpthread.so.0 (0x00000055051eb000)
libm.so.6 => /lib/aarch64-linux-gnu/libm.so.6 (0x000000550521c000)
libgomp.so.1 => /lib/aarch64-linux-gnu/libgomp.so.1 (0x00000055052c7000)
libc.so.6 => /lib/aarch64-linux-gnu/libc.so.6 (0x0000005505315000)
/lib/ld-linux-aarch64.so.1 (0x0000005500000000)
libdl.so.2 => /lib/aarch64-linux-gnu/libdl.so.2 (0x0000005505488000)

I am not sure what else I can do to help you.

[Nichlas-Schmidt]

could be. I read other people had issues on raspberry pi too, its version 5 raspberry

maybe I am not compiling it right? Maybe u could upload the dll/so files you manage to create to dropbox and I can try to use it then I can try to ldd them on my server to see if its outputting right?

[dlemstra]

Why are you compiling anything? You should be able to use the .dll.so file from the NuGet package.

Similar situation and novice cross-cpu-architecture dev here: I'm trying to run my .Net app in a Docker container on a Raspberry PI 5.

When using either Magick.NET-Q16-arm64 (or Magick.NET-Q8-arm64) I get the following error:

2024-08-31T21:22:25.608839600Z System.IO.FileNotFoundException: Could not load file or assembly 'Magick.NET-Q16-arm64, Version=13.10.0.0, Culture=neutral, PublicKeyToken=2004825badfa91ec'. The system cannot find the file specified.

While these files are present in the application directory:

Magick.NET-Q16-arm64.dll 
Magick.NET.Core.dll
Magick.Native-Q16-arm64.dll.so  

However, when using Magick.NET-Q16-AnyCPU I appear to get a little bit more details on assembly loading failure:

2024-08-31T21:43:59.560986661Z System.TypeInitializationException: The type initializer for 'NativeMagickSettings' threw an exception.

While in this case the mentioned files are actually not present, only the following files:

Magick.NET-Q16-AnyCPU.dll
Magick.NET.Core.dll
Magick.Native-Q16-arm64.dll.so
Magick.Native-Q16-x64.dll.so

Does this information help, can I gather more debugging details or describe my sitution better?

Ultimately I would like to be create cross-platform builds with as little platform-specific effort/maintenance as possible of course :)

At some point in the process I also added:
<MagickCopyNativeLinux>true</MagickCopyNativeLinux>
But I don't even know if that affects anything.

I suspect that the library needs something that is not installed on your system. The command file Magick.Native-Q16-arm64.dll.so might give you more information. Maybe it was not copied correctly?

Fridays is my open source day so maybe we can have a look together in a video chat? We are both in the same timezone.

p.s. morgenmiddag kan misschien ook wel.

When using a specifc architecture, I get the following message:

2024-09-10T14:45:26.990310353Z File name: 'Magick.NET-Q16-arm64, Version=13.10.0.0, Culture=neutral, 

Listing the files in the directory returns:

docker exec -it inkycal /bin/sh
/app $ ls -d Magick*
Magick.NET-Q16-arm64.dll        Magick.NET.Core.dll             Magick.Native-Q16-arm64.dll.so 

Please note, on non-arm, the setup does work using anycpu.

Dutch: fijn dat we inde zelfde tijdszone zitten. Voor mij is dit hobby en kan ook inde avonduren. Vrijdagen doorgaans ook, maar niet deze helaas 🚴🏻

I am using the following structure to check which method to execute:

if (RuntimeInformation.ProcessArchitecture == Architecture.Arm64)
  ExecuteArm64()
else if (IntPtr.Size == 8)
  ExecuteX64()
else
  ExecuteX86()

And..... while writing this message I suddenly realized what could be the cause. I suspect that when you run this code in a new .NET application the ExecuteX86() method will be executed because the ProcessArchitecture is Architecture.Arm and not Architecture.Arm64? Can you tell me what IntPtr.Size and RuntimeInformation.ProcessArchitecture are in your application.

I think I will need to update the generated code and throw a better exception when this application runs in an unsupported architecture.

[Atrejoe]

Sorry this took literally over a month, but the answer is in:

Process architecture: Arm
IntPtr.Size: 4

[dlemstra]

Thanks for your response and it looks like you are running arm in 32 bit instead of 64 bit. I suspect there is something in your project settings forcing 32 bit but it might also be possible that you will need to specify that you want to run the application in 64 bit mode.

In the next release of Magick.NET an exception will be raised when an unsupported architecture is detected at runtime.
