Thanks Shree

I already check the link

but when i run

 the following command it generate error

as follow:

C:\Users\emz>cppan --build pvt.cppan.demo.google.tesseract-master

No such file or directory, trying to build as package

Reading package specs...

dependency 'pvt.cppan.demo.unicode.icu.data' not found

C:\Users\emz>cd tesseract

C:\Users\emz\tesseract>cppan

Reading package specs...

note : when i run 

the following command 

Run cppan --build pvt.cppan.demo.google.tesseract-master

Hi,

Try to remove directory c:\users\emz\.cppan\storage and re-run cppan again.

[Essam Zaky]

Thanks Egor

i removed

c:\users\emz\.cppan\storage 

and ran cppan as follow

Run-->cmd

cppan --build pvt.cppan.demo.google.tesseract-master

the cppan crashed atfer the following line

Unpacking  : pvt.cppan.demo.unicode.icu.i18n-58.2.0... 

what should i do

delete the storage again and re run cppan or 

run cppan without clean storage

?

[Egor Pugin]

Please, clean again and run 'cppan --trace --build pvt.cppan.demo.google.tesseract-master'. Post the output here.

[Essam Zaky]

attaced the cmd window log 

note :the strating of log is cleard from cmd window it seems it keeps only the latest logs

thanks

[Egor Pugin]

Ok, then run 'cppan --trace --build pvt.cppan.demo.google.tesseract-master > 1.txt 2>&1' to get the full log and attach 1.txt here. (Of course, remove storage before this command.)

[Essam Zaky]

Hi Egor

 here it's the log attached

cppan did not crash this time

how i check if the process completed successfully or not ?

[Egor Pugin]

Now go to c:\users\yourname\.cppan\storage\lnk\SomeHashDirHere\ and open pvt.cppan.demo.cairographics.cairo-1.15.2.sln.lnk there. Switch to Release configuration in Visual studio and try to build it.

Probably you'll see errors. Now sure what caused them.

Next - try to remove c:\users\yourname\.cppan\storage\src\24\65\930c (whole dir).

Re-run cppan --build pvt.cppan.demo.google.tesseract-master

without deleting whole storage.

[Gowzancha]

I got same error messages as Essam Zaky, I tried 

cppan --trace --build pvt.cppan.demo.google.tesseract-master > 1.txt 2>&1

The 1.txt is attached. Still the cppan crashes.

The directory c:\users\yourname\.cppan\storage\lnk\ is empty.

I tried to remove c:\users\yourname\.cppan\storage\src\24\65\930c

and run again:

cppan --trace --build pvt.cppan.demo.google.tesseract-master > 2.txt 2>&1

The 2.txt is attached. Now when i run tesseract>cppan I got error message:

dependency 'pvt.cppan.demo.unicode.icu.common' not found

I'm using Windows 7 Enterprise, Visual Studio 2012 installed, 

CPPAN downloaded from https://cppan.org/client/cppan-master-Windows-client.zip

[Egor Pugin]

Hi,

I'm trying to track down that issue (crash), but still need more info.

Could you please clear the storage, re-run 'cppan --build pvt.cppan.demo.google.tesseract-master' and attach log files from c:\Users\u\.cppan\ 

cppan.log.info

cppan.log.debug

cppan.log.trace

[Gowzancha]

There is no such log files in c:\Users\u\.cppan\ directory. There is only storage and cppan.yml file.

[Egor Pugin]

Please, update to the latest cppan client: 'cppan --self-upgrade' and try again. Logs must appear.

[Gowzancha]

I did three attempts running:

'cppan --build pvt.cppan.demo.google.tesseract-master'

every time I clean storage and delete the old log files.

As I see the log files look pretty different, it seems that the crashing happens in different points of the process each time!

Please find attached the log files for the three attempts.

[Egor Pugin]

Hi,

I've updated the cppan client with possible fix of your crashes. Please, try to run

cppan --self-upgrade

cppan --build pvt.cppan.demo.google.tesseract-master

[Essam Zaky]

Hi Egor

Should i remove the storage before running these commands

this process takes more than 1 hour

Thanks

[Egor Pugin]

No, try it without removing storage.

[Essam Zaky]

Hi Egor

It's completed now without error or crash

0 Errors

140141 Warning

how to check that process is working fine?

[Egor Pugin]

What process?

[Essam Zaky]

I see some bin files here

C:\Users\emz\.cppan\storage\bin\33e598b5\Release

and some bin files here

C:\Users\emz

Also whare i can find main *.sln 

i would like to build the debug version of tesseract

بتاريخ الأحد، 29 يناير، 2017 4:27:18 م UTC+2، كتب Egor Pugin:

What process?

[Egor Pugin]

1. Right binaries are in the folder from which you call cppan command. Seems it's C:\Users\emz

2. Solution file can be found near those binaries (e.g tesseract-9fa26eb4.sln.lnk). You can open it, switch to debug and build.

3. For other questions, please, read https://github.com/tesseract-ocr/tesseract/wiki/Compiling#windows

[Essam Zaky]

Thanks Egor

Sorry for disturbing you alot

i have another question

i had compared leptonica files in the following path

C:\Users\emz\.cppan\storage\src\14\83\bafc\src

and latest files downloaded from Leptonica site 

https://github.com/DanBloomberg/leptonica

some files are different

should i replace newer files into cppan folders ?

should i do that for all libraries used in the solution ?

[Egor Pugin]

Tess uses stable 1.74 leptonica, not the master branch. You don't need to touch anything in cppan storage.

[ShreeDevi Kumar]

There are recent changes in leptonica which cater to requirements for 4.0.0alpha. so, I think you should build leptonica from the GitHub master for 4.0.

thanks Egor , Shree

Egor,, what do you thin about Shree openion which say "There are recent changes in leptonica which cater to requirements for 4.0.0alpha. so, I think you should build leptonica from the GitHub master for 4.0"

[Egor Pugin]

I do not follow leptonica very closely. If you have strong considerations about leptonica version, ask Zdenko or Ray.

[Essam Zaky]

Shree, I would like to train some Arabic text images , do you think the changes in Leptonica will affact the traning or recognizing process ?

[Essam Zaky]

Dear Egor

In my home machinei,I had built the training and tesseract from source 

by following the following page

https://github.com/tesseract-ocr/tesseract/wiki/Compiling#windows

i faced the follwoing problems

1-I run the follwing 

Run cppan --build pvt.cppan.demo.google.tesseract.tesseract-master

the files binary files are generated but when run tesseract it crash

C:\Users\myloo>tesseractmain 1.tif 1 -l ara

DotProductSSE can't be used on Android

2-sln created not correct ,it contains only 5 project from all tesseract  projects 

what do you think and why detect that my windows machine as Android?

[Egor Pugin]

Hi Essam,

I've updated cppan sources to the latest tess master.

Please, try to re-run the command and check your issues again.

cppan --build pvt.cppan.demo.google.tesseract.tesseract-master

And by the way, what projects do you see in the solution?

Probably you have some build errors, so some projects left unbuilt.

Did you see any errors during the build?

[Essam Zaky]

Hi Igor

Same errors hapen

i did not see any errors while cppan build just warning

the 5 project in the solution file ar

ALL_BUILD.vcxproj

ZERO_CHECK.vcxproj

cppan-d-b.vcxproj

cppan-d-b-d.vcxproj

cppan-d-c.vcxproj

Note : i did not clean the storage and i run the command directly

Best regards

[Egor Pugin]

That's ok.

What about your android error? Does it still exist?

[Essam Zaky]

yes the error still exist when try to launch

This is a lot of 12 point text to test the

Please, write:

1. your processor

2. your windows version

3. visual studio version

[Essam Zaky]

I had downloaded the following version 

http://digi.bib.uni-mannheim.de/tesseract/tesseract-ocr-setup-4.00.00dev.exe

then installed and copied the installed files and replaced the files in cppan build folder "C:\Users\myloo" and run command

tesseract testing\phototest.tif - -l eng

so the installed version is similar to your machine

but when restore the original files built by cppan command

it crash as follow

I'm Using Visual Studio2015 also I have VS2010 installed in the machine

My machine configuration as follow

see the following image

[Egor Pugin]

Try these binaries

https://www.dropbox.com/s/obiqvrt4m53pmoz/tesseract-4.0.0-alpha.zip?dl=1

[Essam Zaky]

I replaced the binaries in the following link 

https://www.dropbox.com/s/obiqvrt4m53pmoz/tesseract-4.0.0-alpha.zip?dl=1

and also crash

Note in the beginning of building using cppan there is message says checking SSE is found, may this help

[Egor Pugin]

Please, check again.

I did some fixes, in general it should work now.

[Essam Zaky]

Hi Egor

Should i remove strorage and tesseract folders?

my last failed trial was to build leptonica 1.7.4 and tesseract 3.05 for Visual studio 2010

[Egor Pugin]

> Should i remove strorage and tesseract folders?

First, try without removing them.

Use tess4.0 and vs2015.

[Essam Zaky]

cppan crash

the first problem appear again when unpack the following module

Unpacking  : pvt.cppan.demo.unicode.icu.common-58.2.0...

here the steps i did

git clone https://github.com/tesseract-ocr/tesseract.git

cd tesseract

cppan

note at the beging of execution of cppan command it says there are new version of client

should now i run cppan --self-upgarde
