Leptonica 1.71 breaks python-tesseract 0.9-0.3 #59

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
This is on a Mac OS X 10.9.4 system with leptonica installed through Homebrew 
(using the standard formula as it was updated to 1.70 a little while ago), 
along with Python installed through Homebrew. I was using python-tesseract for 
a program I'm developing and python-tesseract 0.9-0.3 was working fine. Over 
the weekend, Homebrew updated their formula to leptonica 1.71, which was 
released about a week ago. When I try to run the program now, I get a symbol 
not found error.

What is the expected output? What do you see instead?
I expect to see no output when importing the module. Instead, I get:
dlopen(/usr/local/Cellar/python/2.7.8/Frameworks/Python.framework/Versions/2.7/l
ib/python2.7/site-packages/python_tesseract-0.9-0.3.py2.7-macosx-10.9-x86_64.egg
/_tesseract.so, 2): Symbol not found: _bbufferReadStdin

What version of the product are you using? On what operating system?
python-tesseract 0.9-0.3 on Mac OS X 10.9.4 "Mavericks" with Python 2.7.8.

Please provide any additional information below.
I don't know for sure whether this is a suitable fix or whether it'll break 
other people's programs, but commenting out several function declarations in 
allheaders_mini.h and rebuilding the source fixes the issue. I've attached the 
modified header file. There's several functions that don't appear to exist 
anymore. I probably wouldn't want to put 1.71's header in here, as that will 
likely break the installation for people with 1.70 who don't have the new 
functions introduced with 1.71.

I should mention how I decided what functions to comment out. That was 
accomplished by trying to build the source and seeing several functions being 
declared as not being found when attempting to link with leptonica. I went 
through those errors in the order they were being thrown until the source built.

Can confirm that HEAD
Repository Root: http://python-tesseract.googlecode.com/svn
Revision: 659

builds fine.
