I have the version of tesseract 3.05 and opencv3.2 installed and tested. But when I tried the end-to-end-recognition demo code, I discovered that tesseract was not found using OCRTesseract::create and checked the documentation to find that the interface is for v3.02. Is it possible to use it with Tesseract v3.05 ? How?
i tried to explain the steps
Step 1.download https://codeload.github.com/DanBloomb...
extract it in a dir like "C:/leptonica-1.77.0"
run cmake
where is the source code : C:/leptonica-1.77.0
where to build binaries : C:/leptonica-1.77.0/build
click Configure button select compiler
see "Configuring done" click Generate button and see "Generating done"
Open Visual Studio 2015 >> file >> open "C:\leptonica-1.77.0\build\build\INSTALL.vcxproj" select release, build INSTALL
see "Build: 3 succeeded" and be sure C:\leptonica-1.77.0\build\src\Release\leptonica-1.77.0.lib and C:\leptonica-1.77.0\build\bin\Release\leptonica-1.77.0.dll have been created.
be sure the directory "C:\Program Files\leptonica" is created and files copied into it.
Step 2.download https://codeload.github.com/tesseract...
extract it in a dir like "C:\tesseract-4.0.0"
run cmake
where is the source code : C:/tesseract-4.0.0
where to build binaries : C:/tesseract-4.0.0/build
click Configure button select compiler
see "Configuring done" click Generate button and see "Generating done"
Open Visual Studio 2015 >> file >> open "C:/tesseract-4.0.0\build\ALL_BUILD.vcxproj" build INSTALL
Step 3. in OpenCV cmake set Tesseract_INCLUDE_DIR : C:/Program Files/tesseract/include
set tesseract_LIBRARY C:/Program Files/tesseract/lib/tesseract40.lib
set Lept_LIBRARY C:/Program Files/leptonica/lib/leptonica-1.77.0.lib
when you click Configure button you will see "Tesseract: YES" it means everything is OK
make other settings and generate. Compile ....
lets try to compile together (my cmake output for leptonica as below)
Could NOT find GIF (missing: GIF_LIBRARY GIF_INCLUDE_DIR)
Could NOT find JPEG (missing: JPEG_LIBRARY JPEG_INCLUDE_DIR)
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Could NOT find PNG (missing: PNG_LIBRARY PNG_PNG_INCLUDE_DIR)
Could NOT find TIFF (missing: TIFF_LIBRARY TIFF_INCLUDE_DIR)
Could NOT find ZLIB (missing: ZLIB_LIBRARY ZLIB_INCLUDE_DIR)
Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE)
Configuring done
how about yours?

did you compiled OpenCV from source? here you can find some basic information.
Yes I compiled it from source, but it's not opencv 3.0.0 it's opencv3.2
OK. i am also trying to compile OpenCV with tesseract. i saw your question on SO. it helped me to build tesseract.
we need to know right way to define Lept_LIBRARY tesseract_INCLUDE_DIR tesseract_LIBRARY with cmake on OpenCV compilation
i am also stuck on this point.
maybe http://answers.opencv.org/question/12... will help
I'm also looking at that point.. maybe something missed when building opencv with cmake.
did you get "Tesseract: YES" on cmake while compiling OpenCV
thanks @berak this post http://answers.opencv.org/question/16... seems helpful. i am still trying to find the correct way :)
@sturkmen I don't remember if Tesseract = YES or not.. I have to repeat configuration I think.
