can't start hocr-gtk

[matanya]

after installing hocr 0.10.17 form source I get this traceback:
Traceback (most recent call last):
  File "/usr/bin/hocr-gtk", line 34, in <module>
    from hocr import *
ImportError: No module named hocr

this is on ubuntu 10.4 64 bit.

I expected the program to start but it failed with this traceback.

I could start it in the following q&d way in Lucid Lynx:

after building libhocr-0.10.17 and sudo make install, hocr-gtk is located for me in /usr/local/bin, and hocr.py* lands in
/usr/local/lib/python2.6/site-packages.
I added the following two lines just before line 34 of /usr/local/bin/hocr-gtk

  sys.prefix='/usr/local'
  sys.path.append('/usr/local/lib/python2.6/site-packages')

then hocr-gtk runs, but it still has problems. On most of the images I tried to recognize, the gtk gui hangs at the end of phase 3, Font Recogntion. The command line hocr is perfectly able to cope with these images.

What I find strange about my fix is that python does not know about /site-packages. Indeed:

$ python
Python 2.6.5 (r265:79063, Apr 16 2010, 13:57:41)
[GCC 4.4.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.prefix
'/usr'
>>>

I would have expected sys.prefix='/usr/local'. I don't know if that hints of a python installation problem, with further consequences on hocr-gtk.

Btw an alternative to hocr-gtk is http://code.google.com/p/qhocr/, though it is based on libhocr-0.10.16.

Well, opening bugs on software you built yourself won't get a solution.

I'm working on packaging version 0.10.17 for Debian (and thus ubuntu) which will save you the trouble of self building the software.
