Building Tesseract V4 - Problems

[Mark77]

I'm trying to build version 4 to run with VS2017 with C++ redist 2017.

Following the steps posted on this forum:

cd \petri
mkdir Win64
cd Win64
git clone https://github.com/tesseract-ocr/tesseract tesseract
cd tesseract
cppan  (I assume this wasn't necessary, but I'm trying to avoid improvising)
mkdir Win64 && cd Win64
cppan ..
cmake .. -G "Visual Studio 15 2017 Win64"

and other similar variations to the steps.

Everything appears to go correct right up to 'cmake' at this point i get the failure 'Leptonica_DIR-NOTFOUND'.

Now for the daft question - Do i need to simply include the Leptonica dll files in the Leptonica directory, or a complete new build, or the source? And if so what versions should be used?

Can anyone who has managed this please give me a pointer.


I know there is a version here (https://github.com/tdhintz/tesseract4win64) for c++ redist 2015 but I need to create one for 2017.

Thanks

In my experience all of the dependencies are downloaded automatically.  I did custom builds to statically link everything into just 2 DLLs.  Which cmake did you use?

cmake --version

cmake version 3.8.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

Hi THintz,

Im using  CMake 3.10.0-rc4. A few things are downloaded but not leptonica.

Have you tried the cppan option as given in wiki

I ran the procedure a week ago as described and had no trouble generating an SLN.  The procedure described in the wiki is the same as far as I can tell.  

Actually building the SLN in release mode had a problem unrelated to leptonica and other references.  There is a post here about that.

Check your cppan and cmake output for more clues.

Worked for me after adding cppan, git, and cmake paths
