Unable to load shared library 'libdl' or one of its dependencies on Xubuntu 22.04

[AlexZeitler]

I'm trying to run this sample from the README on Xubuntu 22.04:

using TesseractOCR;
using TesseractOCR.Enums;

var testImagePath = "./in/scan1.png";
using var engine = new Engine(@"./tessdata", Language.English, EngineMode.Default);
using var img = TesseractOCR.Pix.Image.LoadFromFile(testImagePath);
using var page = engine.Process(img);
Console.WriteLine("Mean confidence: {0}", page.MeanConfidence);
Console.WriteLine("Text: \r\n{0}", page.Text);

After sudo apt install libleptonica-dev and symlink-ing libleptonica-1.82.0.dll.so as described in https://github.com/Sicos1977/TesseractOCR/issues/11#issuecomment-1148579216, I got this error:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.
 ---> System.DllNotFoundException: Unable to load shared library 'libdl' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibdl: cannot open shared object file: No such file or directory

The full log from LD_DEBUG=libs dotnet run 2>debug.log:

I also found this post on StackExchange but I don't know what's the way to go now.

[AlexZeitler]

I also have /usr/lib/x86_64-linux-gnu/libdl.so.2 (likely after running sudo apt install libc6-dev libgdiplus libx11-dev)

[AlexZeitler]

sudo ln -s /lib/x86_64-linux-gnu/libdl.so.2 /lib/x86_64-linux-gnu/libdl.so fixed the error message.

Now I get Failed to find library 'libtesseract51.dll.so' for platform x64 but this should be solvable as described in https://github.com/Sicos1977/TesseractOCR/issues/11#issuecomment-1148579216.

Will keep you posted.

[AlexZeitler]

Got it running:

sudo add-apt-repository -y ppa:alex-p/tesseract-ocr5
sudo apt install tesseract-ocr
ln -s /usr/lib/x86_64-linux-gnu/libtesseract.so.5 bin/Debug/net6.0/x64/libtesseract51.dll.so

Created a repo which builds a Docker container and runs a OCR scan: https://github.com/AlexZeitler/tesseract-ocr-dotnet6
