How to create OpenCV binary files from source with tesseact

1.download https://github.com/DanBloomberg/leptonica/archive/1.74.4.zip

extract it in a dir like "E:/leptonica-1.74.4"

run cmake

where is the source code : E:/leptonica-1.74.4

where to build binaries : E:/leptonica-1.74.4/build

click Configure button select compiler

see "Configuring done" click Generate button and see "Generating done"

Open Visual Studio 2015 >> file >> open "E:\leptonica-1.74.4\build\ALL_BUILD.vcxproj" select release, build ALL BUILD

see "Build: 3 succeeded" and be sure "E:\leptonica-1.74.4\build\bin\Release\leptonica-1.74.4.dll" has created image description

build leptonica-1.74.4.lib

2.download https://github.com/tesseract-ocr/tesseract/archive/3.05.01.zip

extract it in a dir like "E:/tesseract-3.05.01"

run cmake

where is the source code : E:/tesseract-3.05.01

where to build binaries : E:/tesseract-3.05.01/build

click Configure button select compiler

set Leptonica_DIR to E:/leptonica-1.74.4\build click Configure button again see "Configuring done" click Generate button and see "Generating done"

Open Visual Studio 2015 >> file >> open "E:/tesseract-3.05.01\build\ALL_BUILD.vcxproj" build libtesseract

and you will see many "Severity Code Description Project File Line Suppression State Error C1083 Cannot open include file: 'allheaders.h': No such file or directory (compiling source file E:\tesseract-3.05.01\textord\tordmain.cpp) libtesseract e:\tesseract-3.05.01\textord\bbgrid.h 30

( maybe there is better ways ) to solve it i copied all *.h files from E:\leptonica-1.74.4\src and E:\leptonica-1.74.4\build\src to E:\tesseract-3.05.01\api

Open Visual Studio 2015 >> file >> open "E:\leptonica-1.74.4\build\ALL_BUILD.vcxproj" "C:\leptonica-1.77.0\build\build\INSTALL.vcxproj" select release, build ALL BUILDINSTALL

see "Build: 3 succeeded" and be sure E:\leptonica-master\build\src\Release\leptonica-1.74.4.lib and E:\leptonica-1.74.4\build\bin\Release\leptonica-1.74.4.dllC:\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 created.

be sure the directory "C:\Program Files\leptonica" is created and files copied into it. image description

Step 2. download https://github.com/tesseract-ocr/tesseract/archive/3.05.01.ziphttps://codeload.github.com/tesseract-ocr/tesseract/zip/4.0.0

extract it in a dir like "E:/tesseract-3.05.01"

create a directory E:\tesseract-3.05.01\Files\leptonica\include

copy *.h from E:\leptonica-master\src into E:\tesseract-3.05.01\Files\leptonica\include copy *.h from E:\leptonica-master\build\src into E:\tesseract-3.05.01\Files\leptonica\include"C:\tesseract-4.0.0"

run cmake

where is the source code : E:/tesseract-3.05.01C:/tesseract-4.0.0

where to build binaries : E:/tesseract-3.05.01/buildC:/tesseract-4.0.0/build

click Configure button select compiler

set Leptonica_DIR to E:/leptonica-1.74.4\build click Configure button again see "Configuring done" click Generate button and see "Generating done"

Open Visual Studio 2015 >> file >> open "E:/tesseract-3.05.01\build\ALL_BUILD.vcxproj" build ALL_BUILDINSTALL

be sure E:\tesseract-3.05.01\build\Release\tesseract305.lib and E:\tesseract-3.05.01\build\bin\Release\tesseract305.dll generated

Step 3. create directory E:\tesseract-3.05.01\include\tesseract

copy all *.h files from

E:\tesseract-3.05.01\api

E:\tesseract-3.05.01\ccmain

E:\tesseract-3.05.01\ccutil

E:\tesseract-3.05.01\ccstruct

to E:/tesseract-3.05.01/include\tesseract

in OpenCV cmake set Tesseract_INCLUDE_DIR : E:/tesseract-3.05.01/includeC:/Program Files/tesseract/include

set tesseract_LIBRARY E:/tesseract-3.05.01/build/Release/tesseract305.libC:/Program Files/tesseract/lib/tesseract40.lib

set Lept_LIBRARY E:/leptonica-master/build/src/Release/leptonica-1.74.4.libC:/Program Files/leptonica/lib/leptonica-1.78.0.lib

when you click Configure button you will see "Tesseract: YES" it means everything is OK

make other settings and generate. Compile ....
