Hi,
Have a look at https://github.com/zdenop/tesseract-mingw
I was/am testing building tesseract by cmake... just with intention to have
one build systems for linux, windows and possibly Mac (but I have no Mac
computer for testing ;-)
I created script (CMakeLists.txt) that was able to compile tesseract (3.02)
on linux and windows (mingw32 and nmake from vs2008).
BUT mingw version was not able to run ("The application failed to
initialize properly (0xc000007b)...". When I search why, I identify there
is problem with usage leptonica library (build by VS2008) in mingw...
Today I remembered that in my older tests (
https://github.com/zdenop/QT-Leptonica) Qt Creator was able to use
leptonica (VS2008 build) in mingw without problem. So I tried to compile
project in QT Creator and it works (also outside QT Creator) ;-) I guess it
is should be question of some mingw options (help is welcomed).
Result can be found in above mentioned repository. I had not time for
testing - I just tried to use tesseract.exe and create test/example for
using tesseract c++ library.
