Hi,
I tried it openSUSE 12.1 and Mandriva Linux 2011.0
Installation on openSUSE was fine - without problem.
Installation on Mandriva Linux was with problem:
$ sudo python setup.py install
[sudo] password for zdeno:
No protocol specified
/usr/lib64/python2.7/site-packages/gtk-2.0/gtk/__init__.py:57: GtkWarning:

If I got it correctly this is because root (or other user) can not open
(gtk) window under "zdeno" login. Solution is to add following lines[1] to
setup.py before line 'from ocrolib import default':
import matplotlib
matplotlib.use('Agg')
'./run-test' produced this error (openSUSE and Mandriva):
...
File "/usr/local/lib/python2.7/site-packages/ocrolib/morph.py", line 50,
in r_dilation
return filters.maximum_filter(image,size,origin=origin)
NameError: global name 'filters' is not defined
I fixed it by adding "from scipy.ndimage import filters" to
ocrolib/morph.py.
On Mandriva I got fatal error due to missing "omp.h". So I need to
install lib64gomp-devel to fix it (in openSUSE this file is part of gcc46
package).
Then I got another error (on Mandriva):
...
+ ocropus-ngraphs 'temp/????/??????.lattice'
Traceback (most recent call last):
File "./ocropus-ngraphs", line 234, in <module>
args.lmodel = ocrolib.findfile(args.lmodel)

in findfile
raise IOError("file '"+path+"' not found in . or
/usr/local/share/ocropus/")
IOError: file '/usr/local/share/ocropus/en-mixed-4.ngraphs' not found in .
or /usr/local/share/ocropus/
This is strange, because all files are installed into /usr in Mandriva (in
openSUSE it is installed to /usr/local), but ./run-test expect files in
/usr/local... I created symlink as workaround. Then ./run-test works ok on
Mandriva.
I hope this help somebody. And I would suggest to add some kind of
integrity check for downloaded models ;-)
