As support for Linux

[goldsam]

Would it be possible to include Linux binaries as well?

[Sicos1977]

How do you mean? The assemblies should just work in .NET on Linux.

[jonaumann]

First of all: Great work, C# needs a free Tesseract5 wrapper! I am also interested in getting it to work on linux (in my case arm64) You need the shared library files for linux (the equivalent for the wrapped dll's on windows) Om ubuntu you get these by installing tesseract via apt: sudo add-apt-repository ppa:alex-p/tesseract-ocr sudo apt update sudo apt install tesseract-ocr

because the dll names are hardcoded, you need to copy the leptonica and tessearct .so from /lib/aaarch64 to the x64 directory under the same name as the dll there, but with ending .so

now the wrapper can read the dll's (.so) BUT: Something is wrong with the wrapper implementation, I get an error: Cannot marshal 'parameter #2': Invalid managed/unmanaged type combination (Marshaling to and from COM interface pointers isn't supported)

So I am stuck here... :-(

[Sicos1977]

Can you turn on debug logging and paste the log overhere so that I can have a look where it is failing? It should log on what method it is failing.

[Sicos1977]

Can you also add the Linux binaries so that I can add them in the nuget package so that people don't have to download them?

[jonaumann]

OK, I got it to work. The Problem was in the TessApi.cs. There were 3 dll imports that used Pix.Image as parameter or return value. The Linux .net marshaller could not handle that, because it was a class, not a primitive or pointer. I just commented out the functions, they are not needed for normal ocr operations. Now it works. Don't know why that works on windows but not on linux.... I cannot give you the linux binaries because they are different for each platform. Mine are only for ubuntu 20 on arm64.

[Sicos1977]

Can you at least show me what you changed so that I can check if the code if it is running on Linux and then use that instead of the Windows way :-)

[jonaumann]

sure, I commented out line 174, 175, 182, 183, 665 and 666. which are the functions TessBaseAPISetInputImage, TessBaseAPIGetInputImage and TessBaseAPIProcessPage.

[nikunj231991]

I am getting the same issue with Linux container

Cannot marshal 'parameter https://github.com/Sicos1977/TesseractOCR/issues/2': Invalid managed/unmanaged type combination (Marshaling to and from COM interface pointers isn't supported)

but don't want to comment functions TessBaseAPISetInputImage, TessBaseAPIGetInputImage and TessBaseAPIProcessPage. So what should be the other way?

[Sicos1977]

Can you enable logging and show me that logtrace?

[Sicos1977]

And do you use the Tesseract dll that is in the nuget package or did you compile one yourself?

[nikunj231991]

Hi Sicos,

Please let me know how I can enable logging for this?

We have used Tesseract dll that is in the NuGet package.

Have added below this 2 lines for missing libraries in Linux Container

RUN ln -s /usr/lib/x86_64-linux-gnu/liblept.so.5 /app/x64/libleptonica-1.82.0.dll.so RUN ln -s /usr/lib/x86_64-linux-gnu/libtesseract.so /app/x64/libtesseract51.dll.so

[nikunj231991]

Hi Sicos,

RUN ln -s /usr/lib/x86_64-linux-gnu/liblept.so.5 /app/x64/libleptonica-1.82.0.dll.so RUN ln -s /usr/lib/x86_64-linux-gnu/libtesseract.so /app/x64/libtesseract51.dll.so

If I remove the above 2 lines then it will throw an error

Failed to find library 'libleptonica-1.82.0.dll.so' for platform x64 at TesseractOCR.InteropDotNet.LibraryLoader.LoadLibrary(String fileName, String platformName) at InteropRuntimeImplementer.LeptonicaApiSignaturesInstance.LeptonicaApiSignaturesImplementation..ctor(LibraryLoader loader)

Just assign a logger to the Engine constructor... see the last parameter in the constructor.

And if I comment TessBaseAPISetInputImage, TessBaseAPIGetInputImage and TessBaseAPIProcessPage methods then working fine, but don't want to do that.

[Sicos1977]

I'll try to look into it today, I need to figure out why it is bugging on Linux and works fine on Windows

[Sicos1977]

Can you check if this commit fixes the marshalling error? f6c85175f54fe2d83fea6e637b4e13880576c759

If so then I'll release a new nuget package

[nikunj231991]

That worked.
