Version 3.03

[Aleksander Grzyb]

I noticed that training instruction was updated to be used with version 3.03 of Tesseract. Anyone know when will be the release of 3.03 version?

[zdenko podobny]

see tesseract-dev forum[1].

I would like to encourage experienced users to test a build system and CONTRIBUTE patch if something is not working. I am able to test linux and (in some extent windows) builds, but I am missing especially Mac OSX, IOS, android user, that can help with 3.03 release.

Also if you would like to include some patch to official release - this is a right time... ;-)

If you are using tesseract C++ API in your program it would be great if you can test current svn (r988) if everything fork for you. Here are few remarks:

•  C API was not updated yet. 
  
• linux build works (if you have correctly installed necessary packages) - tested with gcc and clang
• windows build (tesseract executable and dll)  works in vs2010. I just did quick test with vs2008 and it worked for me too.
• other builds were not tested

HI

I am  also looking for tesseract 3.03 for windows, can any one provide me details about it.

Thank you

[zdenko podobny]

Version 3.03 is not release yet.

So if you are not able to compile it and get information about it (read the source code, look for changes) by yourself, than version 3.03 at this stage is not suitable for you.

To test version 3.03 on windows using cygwin I did the following:

 

install cygwin:

 

Add the following related packages:

 

pkg-config

pango

tif

png

jpeg

make

autoconf

automake

libtool 
libpng12-dev 
libjpeg62-dev 
libtiff4-dev 
zlib1g-dev

pdftk (optional)

Next following this tuto :

  

How to build the tesseract OCR engine on Windows/Cygwin

http://mhoenicka.de/system-cgi/blog/index.php?itemid=2227

 

 

Note : I had to remove  -std=c++11 from CXXFLOAGS in configure and configure.ac.

leptonica 1.70 is easy to add ( see  link mheonicka )

 

 

I must say that I saw a very big improvement in recognition with difficult files from version 3.02.

especially with trained dictionaries. So it is worth the effort.

that simply means your compiler is outdated and you can expect problem (in future...)

Bernard, are you using the latest version of Cygwin? Can you see
what version of gcc/g++ is included? It's surprising to me that the
version included in cygwin would be so old...

[universal reseller]

hi nick

is there any time frame for release 3.03 ?!

It's not decided for sure, as has been mentioned in other threads.
Sometime soon ;)

[Bernard Polarski]

I am using gcc version 4.8.2 (GCC)

[zdenko podobny]

Version 4.8 should support it[1]. So why did you turn off c++11 support? What was error message/problem?

Here is the effect if I leave CXXFLAGS= "-std=c++11:"

In attach the config.log.

Note that this is a cygwin install from scratch and the issue occurred  on 2 different machines.

Configuration is done.

You can now build and install tesseract by running:

$ make

$ sudo make install

$ sudo make install LANGS="eng ara deu"

  Or:

$ sudo make install-langs

Training tools can be build and installed (after building of tesseract) with:

$ make training

$ sudo make training-install

It looks like cygwin bug[1]. Can you please in file ccutil/ambigs.cpp replace line 23 (#include <stdio.h>) with line:

#include <cstdio>

Than try to compile tesseract if it helps.

No changes with #include (cstdio>, still the same error.

I googled a bit, found quite a few references to this bug.
The best was a suggestion to replace -std=c++11 by -std=gnu++0x.

I tried it and it compiled fine however I have no idea
if it is better to have the CXXFLAGS equal to -std=gnu++0X or unset it.

Here is the output with your suggestion:

[Viney Khera]

Hi, 

I am getting same error trying to compile with cygwin. 

I see you mentioned replacing -std=c++11 by -std=gnu++0x worked for you, in which all files you did this replace?

I tried making change in config file but no luck.

I will appreciate any help in resolving this error. 

[zdenko podobny]

Which revision you tried (3.03 is not released yet so providing revision number is must)?

Not sure what revision it is downloaded from google drive but was but able to get it working by making change mentioned earlier in configure file.
