Qt and Tesseract Linkage

@OlegD
All you have done is pasted the whole of the instructions. They are for you to read and act on. Only you know what you did/did not do.Well, I dont know how to make it work with QT.
I've just installed package, realized that there is no instruction for QT and posted to QT forum.
Please advise how can I install it properly for QT environmentI do not see anything related to Qt, or for Qt instructions.
Your code has#include <tesseract/baseapi.h>.
I pointed out that from what you show there are no.hfiles anywhere (that I can see).
I suggested you need to see if that file is anywhere, or sort out whatever you need to do to get it available. Assuming you need that line.
I don't use "tesseract", and I don't suppose anybody else here does either. -
It looks like what you downloaded was just the pre-built binary and associated files to use the tesseract application and not to develop your own. You will have to build the library yourself; just follow the directions that you posted above closely step by step.

@mchinand
So it was just a sample application? And they do not provide the.hfiles with it?Does he really need to build it? IF it comes with pre-compiled external DLLs of whatever to make the (sample?) app work, can't he use those plus
.libs &.hs for his own code without having to build the.dlls? -

Guys, so if I do want to install close to instruction, how can I proceed with this lines?
For visual studio project using tesseract
Setup Vcpkg the Visual C++ Package Manager.
Run vcpkg install tesseract:x64-windows for 64-bit. Use –head for the master branch.
Static linkingTo build a self-contained tesseract.exe executable (without any DLLs or runtime dependencies), use Vcpkg as above with the following command:
vcpkg install tesseract:x64-windows-static for 64-bit
vcpkg install tesseract:x86-windows-static for 32-bit -
@OlegD said in Qt and Tesseract Linkage:
Run vcpkg install tesseract:x64-windows for 64-bit. Use –head for the master branch.
Did you do that?
Otherwise go ask the tesseract people. Qt people do not know anything about this package, we do not know whether it downloads e.g.
.hfiles, only you/tesseract people do. -
Did you manage to install tesseract at all ?
-
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..... -

tesseract/include/tesseract/*.h
I can not run these files
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 -
The Qt installer provides MinGW directly. It has nothing to do with MSys.
