how to compile tesseract on msys2/mingw?

[Simon Eigeldinger]

Hi all,

Now i am back having changed from cygwin to msys2/mingw.
anyone knows how to compile tesseract best on this platform?

i also thought of getting a daily build system to run on linux but i
guess i am a little bit failing with that.
i guess at the moment there is nothing around which builds daily builds
from the source.

greetings,
simon

Modify the pkgbuild to use the latest source.

I had compiled it a couple of years back but do not have all the details now.

The following pages may be helpful:

https://sourceforge.net/p/msys2/wiki/Contributing%20to%20MSYS2/

https://wiki.archlinux.org/index.php/makepkg

An example of fetching the mingw{32,64} repository source, building and then installing a package from it is:

 

git clone "https://github.com/Alexpux/MINGW-packages"
cd MINGW-packages/mingw-w64-tesseract-ocr
makepkg-mingw -sLf
pacman -U mingw-w64-*-python3-*-any.pkg.tar.xz

The -sLf passed to makepkg* means:

Flag Name	Flag Description
-s, --syncdeps	Install missing dependencies with pacman
-L, --log	Log package build process
-f, --force	Overwrite existing package

You will need to update MINGW-packages/mingw-w64-tesseract-ocr/PKGBUILD

and change the source to point to

https://github.com/tesseract-ocr/tesseract/archive/master.zip

or whichever release you want to use

before running makepkg

git clone "https://github.com/Alexpux/MINGW-packages"
cd MINGW-packages/mingw-w64-tesseract-ocr

(change PKGBUILD)

makepkg-mingw -sLf
pacman -U mingw-w64-*-tesseract-ocr-*-any.pkg.tar.xz

(I had copied example of python3 and missed out changing the command for running pacman)

Simon,

You can try the attached pkgbuild for building the latest source from git.

Shree,

I have installed tesseract-ocr dev version 3.5.0 in ubuntu 15.10. It is presumed that version 3.5.00 dev is latest version than 3.04.01 and also no changes effected  on existing traineddata files generated by Ray.

With blessings, sriranga(83+)
