few bullets of instructions do not work..:K
I've posted to Teseract forum, still no respond...
Maybe you can share e-mail or phone from anyone related to Teseract?
Big Thanks in advance -

Still looking for help to install Tesseract with QT
Can pay for help -
Did you manage to install tesseract at all ?

Yes, but it does not work, so I'm asking for help
-
What exactly did you do ?
What was the outcome ?Did you follow the documentation provided by the project itself ?
You seem to have already checked it based on one of your previous answer. However you did not explain what your issue was with them.

If I execute files below thay just do nothing
Download the latest SW (Software Network https://software-network.org/) client from https://software-network.org/client/. Run sw setup (may require administrator access) Run sw build org.sw.demo.google.tesseract.tesseract-master. -

still saying
D:\PROG\May\Tesseract\main.cpp:1: error: tesseract/baseapi.h: No such file or directoryAs I said earlier, you show no signs of having any tesseract
.hfiles at all?I don't think you are reading and following all the instructions. Please do so. For example, in https://tesseract-ocr.github.io/tessdoc/Compiling.html#windows
Checkout tesseract sources
git clone https://github.com/tesseract-ocr/tesseract tesseract && cd tesseract.I can see that would at least give you
tesseract/include/tesseract/*.h, which is what you need..... -

Thank you so much, JonB! -

Now I need to build it according to my librariries...
How can i check what do I actually have?Msys2
Mingw+Msys
Mingw-w64Looking for command as below, to find what do I actually have
C:\Qt\Tools\mingw900_64>gcc -dumpversion
11.2.0 -
The Qt installer provides MinGW directly. It has nothing to do with MSys.

So my next step must be here
Mingw-w64Mingw-w64 allows building 32- or 64-bit executables for Windows. It can be used for native compilations on Windows, but also for cross compilations on Linux (which are easier and faster than native compilations). Most large Linux distributions already contain packages with the tools need for a cross build. Before building Tesseract, it is necessary to build some prerequisites.
For Debian and similar distributions (e. g. Ubuntu), the cross tools can be installed like that:
Development environment targeting 32- and 64-bit Windows (required)
apt-get install mingw-w64
Development tools for 32- and 64-bit Windows (optional)
apt-get install mingw-w64-tools
These prerequisites will be needed:
libpng, libtiff, zlib (binaries for Mingw-w64 available as part of the GTK+ bundles) libicu liblcms2 openjpeg leptonicawhat should i exactly do?
-
Why are you following the cross-compilation instructions from Linux to Windows ?

Is there the similar command line in MinGW that supplied by QT?
-
If memory serves well, you should have some shortcuts in the start menu that starts a command line instance that is ready to use with MinGW.

Oh, It seems I'm step behind to finish this insane journey..
How can I build it with QT now? -
As usual, point INCLUDEPATH to that folder, then LIBS to the one containing the library files and link against these libraries.
