1. Why you are building debug tesseract?
2. Why you are mixing build tools (cmake for leptonica and autotool for
rest)? There was reported issue regarding this mix in case of
leptonica->tesseract...

Hello all
I could not find a proper documentation explaining each step explicitly
regarding the compilation from source including leptonica and some other
image libs.
Therefore I created my own scripts and wanted to share them here. Hopefully
others might benefit as well.

I do not use vcpkg. I suggest you to use cppan (you need to install it and
put to path). For me it stupidly easy and it takes cca 15 minutes on my
computer and internet network):
gir clone https://github.com/tesseract-ocr/tesseract.git
cd tesseract
mkdir build64
cd build64
cppan..
cmake .. -G "Vi
Please do not use tesseract 4.0 alpha. There have been many changes since
then.
Use the latest code from github, which is 4.0.0-rc3 or install from Alex's
PPA or from ub mannheim (for Windows).
Please read the wiki pages about training for new font for tesseract 4 -
fine tuning for Impact.

Your post are valuable for me, it is first time when I try to use tesseract.
Regarding compiling leptonica and tesseract, it's endless story :)
I have taken from here: https://github.com/Microsoft/vcpkg vcpkg, and
generated the exe from .bat file.
And then I have tried this command in console: *v

Did AUTO improve results?
Work from uncompressed e.g. png Try this resize:
using (Bitmap large = ResizeImage(png, (int)(png.Width * 3.125),
(int)(png.Height * 3.125)))
{
// Apply filters
// tess here
}
public static Bitmap ResizeImage(Image image, int width, int height)

I have convert dpi of image by imagemagick to be 300 dpi and try it again with
same result.

most easy way for you would be to compile tesseract on windows with cppan.
instruction are on wiki...

Hi. I can help you, with a desktop app that will do what you need. Just
give me details regarding your task ... ex. What you need to display the
desktop app, etc. Or, we can build together this app ... it is up to you.

Thank you a lot for your prompt answer ! I really appreciate that !
I have run in cmd line: tesseract --help-extra, I don't spot any graphic
library option.
I have to tell you that I am using Windows10, and I have compiled leptonica
with VS2017, taken from here: https://github.com/danbloomberg/
Is here anybody who build&use tesseract on Android?
I would like to solve:

You should uninstall (purge) v3 first. Then build the v4 from scratch.

When I did pre-processing I get result more bad, the idea is when I recognize
document in Arabic I get it almost correct and when I recognize document in
English I get it correct but when I recognize document in Arabic+English
“Multiple” I get allEnglish word in digits .. how to fix it ?
From:
Really? Where did you look???
What is output of leptonica "./configure --help" ??? What is printed on
screen when you run leptonica configure?

You forget to uninstall tesseract 3.04 obviously.
You can not have 2 installation of tesseract or you should know your system
and have knowledge how to handle this kind of situation.
What ever you do, you should understand what are you doing.
